The invasion violated the Games’ Olympic Truce, which says nations should not attack each other from 1 week before the Olympics to 1 week after the Paralympics.
Belarus was implicated for allegedly allowing Russia to use its territory for military purposes.
In October 2023, the Russian Olympic Committee was suspended after declaring authority over Ukrainian sports organizations in certain regions.
Political Neutrality and Violations
The IOC cited Russia’s International Friendship Association (IFA) as a political body violating the IOC charter.
The charter states that sports organizations within the Olympic Movement shouldapply political neutrality.
Russia’s announcement of the Friendship Games in 2024 led to accusations of politicizing sports.
Critics note the concept of “political neutrality” is not based on objective criteria and is challenging to interpret consistently.
What is Individual Neutral Athletes (AINs)?
The IOC allows athletes from these countries to participate as individual-neutral athletes (AINs).
Athletes must not represent their country or any associated organization.
They cannot actively support the Russian invasion of Ukraine.
AINs are athletes with Russian or Belarusian passports qualified through existing qualification systems.
They will compete under a neutral flagand uniform, with a neutral song played if they win medals.
The audience cannot wave their flags.
Do you know?
The Indian Olympic Association was suspended in 2014, leading to three athletes competing under the Olympic flag.
From UPSC perspective, the following things are important :
Prelims level: About Machine Unlearning (MUL)
Mains level: Significance of Machine Unlearning (MUL)
Why in the news?
The emergence of artificial intelligence has revolutionized various facets of our lives and has even prompted us to reevaluate our concepts of the mind, brain, and consciousness.
Antithesis of Machine Learning (ML):
Machine Unlearning (MUL) is considered the antithesis of Machine Learning (ML). It was first proposed by Cao and Yang in their work “Towards Making Systems Forget with Machine Unlearning.”
Machine Unlearning focuses on the ability to make AI models forget specific data they have learned. This concept addresses the challenges of removing or correcting sensitive, false, incorrect, or outdated information from trained AI models.
While ML is about learning from data to make predictions or decisions, MUL aims to reverse this process, ensuring that certain data can be effectively and completely erased from the models.
This concept is crucial for maintaining data privacy, reducing AI bias, and complying with regulations that require the deletion of personal or sensitive information.
Implementation approaches
Private Approach: Data fiduciaries voluntarily implement MUL algorithms, allowing flexibility but potentially limiting access for smaller companies due to cost and expertise barriers.
Public Approach: Governments can legislate requirements for MUL implementation, potentially creating a standard framework that data fiduciaries must follow. This can include guidelines under existing data protection laws, as seen in the EU’s AI Act, which addresses data poisoning and mandates security controls.
International Approach: This emphasizes the need for a global framework for MUL, recognizing that AI innovations have cross-border implications. International standard-setting organizations could play a crucial role in developing these standards
Techniques for Machine Unlearning
Exact Unlearning: This method completely removes the influence of specific data points from the model.
Approximate Unlearning: Instead of fully erasing the data’s influence, this technique minimizes its impact on the model’s predictions to an acceptable level.
Data-Centric Approaches: Techniques like data reorganization and pruning are employed to manage the dataset, making it easier to identify and remove unwanted data points.
Model-Centric Approaches: These methods involve manipulating the model parameters directly. For example, algorithms can adjust the weights associated with the data points that need to be forgotten, thereby reducing their influence on the model’s outputs.
Prompting-Based Methods: In large language models (LLMs), developers can use carefully crafted prompts to induce behaviours that mimic unlearning.
Algorithmic Innovations: New algorithms, such as MU-Mis, focus on minimizing the contribution of specific data points to the model’s decision-making process.
Way forward:
Development of Standardized Frameworks: The need to establish a comprehensive regulatory framework for MUL can facilitate its adoption across various sectors. Governments and international organizations should collaborate to create guidelines that mandate the use of MUL techniques for data privacy compliance, similar to the EU’s AI Act.
Investment in Research and Education: The need to increase funding and resources should be directed toward research in machine unlearning techniques and their applications.

Political Will: Chief Minister A. Revanth Reddy has shown political will by advocating for awareness among politicians and celebrities, although this has led to legal disputes.
Legal Status of Marijuana
General Prohibition: Marijuana, including its various forms such as ganja (flower), charas (resin), and hashish, is illegal under the NDPS Act. It talks about the possession, sale, and production of these substances are criminal offences.
Bhang Exception: Bhang, made from the leaves and seeds of the cannabis plant, is legally consumed in many parts of India, especially during religious festivals. It is not classified as an illegal substance under the NDPS Act.
State Variations: Different states have their own regulations regarding cannabis. For example, Uttarakhand has legalized the commercial cultivation of hemp, while Odisha has a more lenient approach to recreational use. This leads to a patchwork of laws across the country.
Penalties: The NDPS Act prescribes severe penalties for drug offences.
Possession of small quantities can lead to imprisonment of six months to one year and fines of up to ₹10,000. For larger quantities, penalties can escalate to 10-20 years of imprisonment and fines of ₹1-2 lakh.
Requires Smart thinking and Policing (Way forward)
Focus on Trade, Not Users: The emphasis should be on dismantling the drug network rather than just catching users. This approach was advocated by Home Minister Amit Shah.
Avoiding Witch Hunts: The fight against drugs should not lead to the targeting of specific localities or public shaming of institutions.
Need Economic Considerations: Measures such as shutting down nightlife venues before midnight could harm the economy and the business environment.
Implement Integrated Approach: A comprehensive strategy is needed that involves smarter policing, better use of technology, and effective legal actions against producers and suppliers rather than users.

Prelims level: Landslides, Landslide Atlas of India
Why in the News?
Many people have died, and hundreds are feared trapped after three landslides hit Kerala’s Wayanad district.
About Wayanad
Wayanad is the only plateau in Kerala, forming a continuation of the Mysore Plateau, part of the Deccan Plateau.
The Kabini River, a tributary of the Kaveri River, originates in Wayanad.
The Chaliyar River, the fourth longest river in Kerala, also originates on the Wayanad plateau.
Wayanad is home to the Wayanad Wildlife Sanctuary.
Susceptibility to Landslides:
The region predominantly has laterite soil, which is highly prone to erosion.
The steep and undulating terrain of Wayanad makes it naturally susceptible to landslides.
Wayanad receives intense and prolonged monsoon rains that cause water infiltration, leading to soil saturation and increased pore water pressure, which destabilizes slopes.
Large-scale deforestation for agriculture and settlement reduces the binding capacity of the soil and its ability to absorb water, exacerbating the risk of landslides.
What are Landslides?
A landslide is the downward and outward movement of materials including rock, earth, or debris down a slope due to gravitational force. Landslides are disasters of hydrogeological origin, resulting from the failure of materials falling down a slope due to gravity.
India is among the top five landslide-prone countries globally, with at least one death per 100 sq km reported annually due to landslides.
Regional Distribution
North-western Himalayas: 66.5% of landslides.
North-eastern Himalayas: 18.8% of landslides.

Prelims level: FnCas9 Enzyme
Why in the News?
Scientists from the “CSIR-Institute of Genomics and Integrative Biology” have developed an enhanced genome-editing system using FnCas9that can modify DNA more precisely and more efficiently than existing CRISPR-based technologies.
CRISPR occurs naturally in some bacteria, as a part of their immune system that limits infections by recognizing and destroying viral DNA.
What is FnCas9?
FnCas9 is a variant of the Cas9 enzyme derived from the bacterium Francisella novicida.
It is used in genome editing technologies, particularly within the CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) system, to make precise modifications to DNA sequences.
What is CRISPR-Cas9 System?
CRISPR-Cas9 is a revolutionary genome-editing tool adapted from a natural bacterial defense mechanism against viruses.
Bacteria use CRISPR sequences to store segments of viral DNA, which helps them recognize and combat viruses in subsequent infections.
The most commonly usedCas9 enzyme is derived from Streptococcus pyogenes.
Mechanism:
Guide RNA (gRNA): A specifically designed RNA molecule that matches the target DNA sequence.
Cas9 Enzyme: Acts as molecular scissors that cut DNA at a location specified by the gRNA.
Proto-spacer Adjacent Motif (PAM): A short DNA sequence adjacent to the target site that Cas9 must recognize and bind to in order to cut the DNA.
DNA Repair: Once the DNA is cut, the cell’s natural repair mechanisms either repair the break or introduce desired genetic changes.
Applications:
Agriculture: Enhancing crop yield and nutritional value.
Healthcare: Diagnosing and treating genetic disorders.
Research: Studying gene functions and interactions.
Challenges with Traditional Cas9: SpCas9 can sometimes cut DNA at unintended sites, leading to potential unintended genetic modifications.
How FnCas9 overpowers traditional Cas9 (SpCas9)?
FnCas9 is known for its higher specificityin targeting DNA sequences compared to SpCas9, resulting in fewer off-target effects.
More accurate targeting reduces unintended genetic modifications.
It ensures more reliable and safer genome editing.
Achievements by Indian Scientists
Scientists at the CSIR-IGIB in New Delhi have modified FnCas9 to enhance its efficiency without compromising specificity.
Key Modifications include:
Amino Acid Tinkering: Researchers modified amino acids in FnCas9 that interact with the PAM sequence to increase binding affinity.
Improved Binding: Enhanced binding affinity allows FnCas9 to sit more securely on the DNA, improving gene-editing effectiveness.
Flexibility: The enhanced FnCas9 can access and edit hard-to-reach regions of the genome.

Prelims level: About Dark Oxygen
Mains level: Impact of Deep-Sea Mining
Why in the News?
Scientists reported on July 22 in Nature Geoscience that an unknown process is generating oxygen in the deep oceans, where photosynthesis is not possible due to the lack of light.
About the recent study:
Discovery of Oxygen: Scientists reported an unknown process producing oxygen in the deep ocean, specifically in the abyssal zone, where photosynthesis is not feasible due to insufficient sunlight.
Location of Study: The study was conducted in the Clarion-Clipperton Zone, located off Mexico’s west coast, which is known for having the highest concentration of polymetallic nodules.
Oxygen Measurement: At a depth of 4 km, researchers observed unexpected increases in oxygen levels, sometimes tripling within two days, contrary to expectations of decreasing levels due to consumption by marine life.
Source of Oxygen: The researchers hypothesized that the oxygen could be generated by polymetallic nodules, which may create electric charges that split water molecules, releasing oxygen. The nodules exhibited voltages up to 0.95 V, suggesting they could function like battery cells.
What is Deep-Sea Mining?
Deep-Sea Mining: It involves extracting minerals from the ocean floor at great depths, targeting resources such as polymetallic nodules, polymetallic sulphides, and cobalt-rich ferromanganese crusts.
Economic and Strategic Importance of Deep-sea Mining:
Resource Potential: The Clarion-Clipperton Zone holds substantial reserves, including 6 billion tonnes of manganese, and over 200 million tonnes each of copper and nickel, making it a significant target for future mining operations.
International Contracts: The International Seabed Authority has granted exploration contracts to various contractors, including the Government of India, for deep-sea mining activities.
What is Dark Oxygen?
“Dark oxygen” refers to the oxygen found in the deep ocean, specifically in regions where photosynthesis cannot occur due to the absence of sunlight. In such areas, known as the abyssal zone, oxygen levels are typically low and depend on global ocean circulation for replenishment.
Impact of Deep-Sea Mining
Ecological Concerns:
Potential Damage: The recent findings highlight the potential risks of deep-sea mining to unique marine ecosystems that depend on ‘dark oxygen’. There is concern that mining could disrupt these ecosystems, leading to significant and possibly irreversible environmental impacts.
Historical Evidence: Previous experiments, such as the DISCOL Experiment, have shown long-term ecological damage from simulated mining activities, including reduced biodiversity and altered sedimentological profiles.
Industry Response and Challenges:
Insurance Withdrawal: In response to growing concerns, major European insurance companies announced they would exclude deep-sea mining from their underwriting portfolios.
Sustainability Issues: The new discovery of ‘dark oxygen’ adds complexity to the debate on deep-sea mining. If sustainable practices are not implemented, such mining could become unfeasible due to its potential negative impacts on marine ecosystems.

Prelims level: About National Mission on Natural Farming (NMNF)
Mains level: Concerns related to Natural Farming
Why in the news?
In the 2024-25 Budget proposals, Union Finance Minister Nirmala Sitharaman declared that over the next two years, one crore farmers nationwide will be introduced to natural farming, with support provided through certification and branding.
National Mission on Natural Farming (NMNF):
The National Mission on Natural Farming (NMNF) aims to encourage farmers to adopt chemical-free farming practices and willingly shift to natural farming based on the merits of the system.
The government believes the success of NMNF hinges on changing farmers’ behaviour to transition from chemical-based inputs to cow-based, locally-produced inputs, supported by a financial outlay of ₹4,645.69 crore over six years (2019-20 to 2024-25) under the ‘Bharatiya Prakritik Krishi Paddhati’ scheme.
What is natural farming?
Natural farming avoids the use of chemical fertilizers and pesticides, instead promoting traditional indigenous practices.
It focuses on recycling on-farm biomass, employing biomass mulching, and utilizing formulations made from cow dung and urine.
Pests are managed through diverse farming practices and on-farm botanical mixtures, strictly excluding all synthetic chemical inputs.
What are the concerns related to Yield?
Yield Reduction: Agricultural experts are concerned that a large-scale transition to natural farming could result in reduced crop yields. Studies have shown significant declines in yield for staples like wheat (59%) and basmati rice (32%) compared to integrated crop management systems.
Food Security: Lower yields from natural farming could threaten food security in a populous country like India, potentially only being able to feed around one-third of the population with staples like wheat and rice.
Findings on the Ground:
Mixed outcomes: Field experiments have shown mixed results. Some studies indicate improved yields and incomes with lower costs due to biological inputs, while others show a decline in productivity.
Good Results in Andra Pradesh: In Andhra Pradesh, adopting natural farming methods has shown promising results, leading to better crop yields and enhanced farmers’ incomes.
Concerns about sustainability and productivity: Agro-scientists from the Indian Council of Agricultural Research (ICAR) and the Indian Institute of Farming Systems Research (IIFSR) have raised concerns about the sustainability and productivity of natural farming methods.
Differences in Studies:
CESS Study: The Centre for Economic and Social Studies (CESS) and Institute for Development Studies Andhra Pradesh found that natural farming practices led to improved yields and incomes for farmers, thereby enhancing food and nutritional security.
ICAR-IIFSR Study: The study by ICAR-IIFSR reported a significant decline in yields of key crops like wheat and basmati rice when compared to conventional farming practices, suggesting a negative impact on food supply.
Case study of Sri Lanka:
Policy Shift: Sri Lanka’s decision to completely switch to organic farming and ban chemical fertilizers led to economic and political turmoil.
Yield Decline: Farmers struggled to obtain natural fertilizers, resulting in reduced yields of key crops, including rice.
Food Security Risk: The shift put the country’s food security at risk, causing sharp price escalations and widespread protests and unrest.
Way forward:
Localized Implementation and Scientific Validation: Need to conduct rigorous scientific studies and extensive field trials to validate the productivity and viability of natural farming methods before scaling them up nationwide.
Hybrid Approach and Support for Farmers: Govt. should adopt a hybrid approach that combines the best practices of both natural and conventional farming to ensure food security.

Prelims level: Right to be Forgotten
Mains level: Key judgments related to the Right to be forgotten
Why in the News?
Last week, the Supreme Court agreed to hear a case that could define the scope of the “Right to be Forgotten” referred to in European privacy law as the “Right to Erasure” in India.
What is the ‘Right to be Forgotten’?
The right to be forgotten allows individuals to remove or de-index their personal information from the internet if it infringes on their right to privacy. It is based on the principle that personal data should be removed when it is outdated, irrelevant, or no longer necessary.
Affirmed by the Court of Justice of the European Union (CJEU) in the “Google Spain case” (2014), which ruled that search engines must remove data if it is inadequate, irrelevant, or excessive in light of the time elapsed.
Under the EU’s General Data Protection Regulation (GDPR),Article 17 describes the right to erasure, reflecting the concept of informational self-determination.
How is this ‘Right’ interpreted in India?
Absence of Statutory Framework: India lacks specific legislation explicitly addressing the right to be forgotten.
Judicial Interpretation: The 2017 Supreme Court ruling in Justice K.S. Puttaswamy v. Union of Indiarecognized the right to privacy as a fundamental right. Justice S.K. Kaul’s concurring opinion suggested that the right to be forgotten involves removing personal data that is no longer necessary or relevant.
Judicial Guidelines: Justice Kaul outlined valid justifications for overriding this right, including freedom of expression, legal compliance, public interest, and research purposes.
How have Courts ruled on the Issue?
Rajagopal vs. State of Tamil Nadu (1994): The Supreme Court recognized a “right to be let alone” but differentiated it from public records, including court decisions. Once something becomes public, privacy rights are diminished.
Dharamraj Bhanushankar Dave vs. State of Gujarat (2017): Gujarat HC refused to remove details of an acquittal, asserting that court orders should remain public.
The Registrar General (2017): Karnataka HC protected the name of a petitioner in a sensitive annulment case, aligning with trends in Western jurisdictions.
Delhi HC (2021): Extended the right to be forgotten to criminal cases, allowing details of an acquittal to be removed from search results to protect the petitioner’s career prospects.
Orissa HC (2020): Noted the need for a broader debate on the right to be forgotten, particularly concerning “revenge porn” and online content.

Prelims level: Agarwood
Why in the News?
India successfully prevented the inclusion of Aquilaria malaccensis (agarwood) in the Review of Significant Trade (RST) of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).
CITES notified a new export quota for Aquilaria malaccensis from India, effective April 2024.
What is Agarwood?
Agarwood (the Wood of Gods) also known as “Oud,” is a highly valuable and aromatic resinous wood produced by the Aquilaria tree.
The resin forms in the heartwood of the tree when it becomes infected with a particular type of mold (Phialophora parasitica).
This infection causes the tree to produce a dark, fragrant resin, which is highly sought after for its distinctive aroma.
This contains essential oils with compounds like sesquiterpenes, chromones, and phenylethyl chromone derivatives.
It thrives in tropical forests, at altitudes up to 1000 meters, often found in areas with high humidity and rainfall.
Conservation Status:
IUCN Status: Listed as Critically Endangered.
CITES: Listed in Appendix II in 1995 based on India’s proposal at CoP9 in 1994.
Uses of Agarwood
It is traditionally used as incense.
Extracts (agarwood oil) are used in perfumes, the aroma industry, medicine, air fresheners, and purifiers.
Essential oil has anti-inflammatory, anti-rheumatic, analgesic, and anti-oxidant properties.
Agarwood cultivation is prevalent in parts of India, especially in the Northeast.
This development will benefit lakhs of farmers in districts of Assam, Manipur, Nagaland, and Tripura.
What is the issue over the inclusion of ‘Agarwood’ (Aquilaria malaccensis) in the RST of the CITES list?
Aquilaria malaccensis was listed in Appendix II of CITES in 1995, which means its trade is controlled to avoid utilization incompatible with its survival.
The RST process assesses whether trade in a species is detrimental to its survival and recommends actions to ensure sustainability.
India’s stance was supported by a study conducted by the Botanical Survey of India (BSI), which suggested that the harvest from wild populations should be prohibited, while allowing harvest from plantations and private/community lands.
Arguments against Inclusion in RST
Controlled Harvesting: India argued that it has established controlled harvesting practices, ensuring that only cultivated agarwood is used for trade.
Economic Impact: Inclusion in the RST could have disrupted the livelihoods of farmers and traders who depend on agarwood cultivation, particularly in the northeastern states of Assam, Manipur, Nagaland, and Tripura.
Sustainable Practices: The NDF indicated that the current practices in India were sustainable and that the species was being cultivated widely, reducing pressure on wild populations.
New Export Quota
Establishment of Quota: CITES notified a new export quota for agarwood from India, effective from April 2024. The quota was set at 1,51,080 kg/year for agarwood chips and powder/sawdust, and 7,050 kg/year for agarwood oil.
Formal Trade: The absence of an export quota for a long period had led to informal trade and increased prices. The new quota aims to regulate and legalize the trade, ensuring benefits to local growers and the economy.

Prelims level: Shift in snowfall patterns in Himachal, Rivers and glaciers located
Why in the News?
Himachal Pradesh is experiencing a reducing snow cover over the years.
There is a noticeable shift in snowfall occurrence from winter months towards early summer months.
Findings from the Latest Study:
The study by the Centre on Climate Change of Himachal Pradesh Council for Science Technology-Environment (HIMCOSTE) shows an overall decrease of 12.72% in snow cover area in 2023-24 compared to 2022-23.
The study used Advanced Wide Field Sensor (AWiFS) satellite data to analyze snow cover trends.
Early winter months (October-November) showed a decrease in snow cover area except for the Ravi basin, which showed a marginal increase in October.
Peak winter months (December-January) saw a negative trend in snow cover area.
Late winter months (February-March) showed a positive trend with an increase in snow cover area in all basins compared to the previous year.
Snow cover area increased in April due to fresh snowfall in the early summer period.
Impact on Water Availability
The decrease in snow cover during peak winter months (December and January) is especially alarming.
Snowfall during these months sustains longer and enhances the discharge dependability of major river basins during summer.
Reduced snow cover in winter could affect water availability during the summer months.
Concerns and Implications
Environmentalists and scientists are concerned about the shifting snowfall patterns.
Depleting snow cover and changing snowfall patterns have significant impacts on hydro-power, water sources, people, livestock, forests, farms, and infrastructure.

Prelims level: Indexation, Capital Gains Tax Regime.
Why in the News?
The withdrawal of theindexation benefit from the long-term capital gains (LTCG) tax regime has emerged as a contentious decision in the Union Budget for 2024-25.
What is Indexation?
Indexation is a method used to adjust the purchase price of an asset to account for inflation over the period it was held.
This reduces the taxable capital gain, as it reflects the increase in the asset’s value due to inflation.
Purpose: To ensure that the taxpayers are taxed only on the real gains and not on the inflationary increase in the value of the asset.
Changes in the LTCG Regime
The new LTCG regime removes the indexation benefit for property, gold, and other unlisted assets.
The LTCG tax rate is reduced from 20% to 12.5%.
For assets purchased before 2001, the fair market value as of April 1, 2001, is considered the cost of acquisition.
Implications of the Changes
The government claims the changes simplify the capital gains tax structure without causing a loss to most taxpayers.
The uniform tax rate for various asset classes is intended to benefit both taxpayers and tax authorities.
Concerns for Taxpayers
There was significant concern, particularly in the residential real estate sector, about increased LTCG tax liabilities.
The government clarified that the new regime would be beneficial in most cases, as real estate returns typically outpace inflation.
The Income Tax Department explained that:
For properties held for 5 years, the new regime is beneficial if the value has appreciated 1.7 times or more, and
For 10 years, if the value has increased to 2.4 times or more.

Prelims level: Location of Manila Bay
Mains level: Impact of oil spill on environment
Why in the news?
Typhoon Gaemi caused widespread damage in Taiwan, the Philippines, and southeastern China, leading to the sinking of the oil tanker MT Terra Nova in Manila Bay.
MT Terra Nova Incident
The MT Terra Nova, an oil tanker, capsized in Manila Bay due to severe weather conditions caused by Typhoon Gaemi. It was en route to Iloilo, Philippines, when it sank, resulting in one crew member’s death and the rescue of 16 others.
The sinking of the MT Terra Nova has raised alarms about a potential oil spill that could become the largest in Philippine history, threatening marine life and coastal ecosystems. The spill has already spread several kilometers, prompting urgent containment efforts.
The Philippines’ Coast Guard and other agencies are deploying containment booms and skimmers to mitigate the environmental damage. Booms are used to slow the spread of oil, while skimmers are boats that remove oil from the water surface.
How Oil Spills impact the environment?
Immediate Effects on Marine Life: Oil spills disrupt photosynthesis in marine plants and phytoplankton, which are crucial for oxygen production. The toxic exposure from oil can harm fish and other marine animals, particularly those near the surface.
Impact on Birds: Oil can coat the feathers of birds, compromising their insulation and leading to hypothermia and drowning.
Long-term Ecological Damage: Oil spills can result in bioaccumulation of toxic substances in the food chain, affecting higher-level predators, including humans.
Threat to Coastal Ecosystems: Coastal habitats like mangroves, coral reefs, and marshlands are especially vulnerable, as oil can suffocate these environments and kill vital plants and animals. Recovery from spills can take decades, with some species facing extinction.
Economic Impact: Communities that rely on fishing and tourism suffer economically due to oil spills, as cleanup efforts are costly and lengthy, diverting resources from other critical areas.
Major Oil Spills from the Past
Exxon Valdez Spill (1989): One of the worst oil spills, it released approximately 11 million gallons of crude oil into Prince William Sound, killing an estimated 250,000 seabirds, 2,800 sea otters, and numerous other marine animals.
Deepwater Horizon Disaster (2010): This incident saw an estimated 210 million gallons of oil spill into the Gulf of Mexico over 87 days.
Conclusion: Need to implement advanced containment measures and cleanup technologies to effectively manage oil spills. This includes deploying more sophisticated skimmers and absorbent materials, as well as utilizing drones and remote sensing to monitor the spread of oil and assess environmental damage.
