What's the situation? A stricken ship has leaked over 1,000 tons of oil over the coast of Mauritius. Experts fear that the ship may soon break in half, which could have devastating effects on the surrounding environment.
How did it happen? It is believed that harsh weather conditions caused the leak.
Who caused it? The cracked vessel, MV Wakashio, is operated by the Japanese Mitsui OSK Lines.
More facts The spill occurred near two environmentally protected marine ecosystems, as well as the Blue Bay Marine Park reserve. There are also mangrove plantations and well-known beaches nearby.
Threatened birds, captive fruit bats, and thousands of plants were removed from a nearby island, Ile aux Aigrettes by conservation activists.
Using technology to mitigate spills Human error is the leading cause for maritime accidents.
By integrating AI into the complicated world of global transportation, we can reduce and possibly even eliminate the risks associated with long-distance, heavy-duty shipping routes.
- Use predictive analysis to prevent spills
- Expedite response-time
- Mitigate risks for clean-up efforts
Bottom line Using AI in shipping and clean-ups lessens the risk of future spills, and reduces the impact of existing disasters.

How it works
- When microorganisms (e.g.bacteria) break down organic matter like manure and food waste anaerobically (without oxygen), biogas is released. Bio gas consists primarily of carbon dioxide and methane - one of the primary components of natural gas.
- Farmers place animal manure, food waste and agricultural waste in an anaerobic digester with a pipe to extract the gas.
- The solid byproduct is used as livestock bedding, soil amendments or in biodegradable planting pots, and the liquid byproduct is a nutrient-rich fertilizer.
Benefits of Biogas-based Energy
- Reduced greenhouse gas emissions. Biodigesters divert carbon dioxide and methane that would normally be released into the atmosphere. Greenhouse gas emissions from a dairy farm can be reduced by 35% when biogas-based electricity replaces grid-based electricity.
- Cost savings. On-site biodigesters help farmers save on electricity bills and fertilizer. A farmer told The Washington Post that he saved anywhere from $75,000 to $100,000 a year on electricity, heating, fertilizer, and animal bedding with a biodigester.
- Renewable. Biogas is generally considered renewable as it is produced by animal and plant waste and the source is not limited in quantity like coal or natural gas.
- Biogas generation is becoming increasingly popular. From 2000 to 2020, the number of operational anaerobic digesters in the United States has grown from 24 to 255.
- Biogas is a popular mode of energy production in India and China, which have 4.54 million and 27 million biogas plants respectively.
- As the world divests from fossil fuels, new and varied energy sources will be necessary to satisfy the energy needs of the world and biogas can help. Biogas just goes to show you that not all waste is useless. One cow’s waste is another man’s treasure.

The scoop Market research firm JD Power released a new index based on environmental, social and governance (ESG).
- Consumer awareness and engagement with utility climate initiatives are very low
- Most concerned cities: NYC, LA and Portland are most concerned cities on climate change
- Climate change skeptics: Wyoming and Alabama have the largest percentages of climate change skeptics
- Business customers more engaged in sustainability than residential customers
Why it matters Sustainability has a communication and education problem. Companies in traditional industries like electricity need to adapt marketing initiatives to match 21st century tools, and communicate better with consumers.

What to know
- Over 332 active fires are burning over 1.6 million hectares of land in Siberia
- Parts of the Arctic Circle have been burning since July 2019
- These wildfires originated from a combination of natural causes including temperatures reaching 30 ℃, wind, and dry thunderstorms
- The cost-benefit ratio of saving these ecosystems indicates that Siberia should let the wildfires burn until rain comes because most of them are not directly endangering civilization
- These fires are so humongous their smoke blew across the North Pacific Ocean and the Bering Sea to reach Oregon, Alaska, and Canada
- Wildfires are destroying valuable ecosystems in the Arctic Circle
- High temperatures melted the permafrost early, releasing the carbon dioxide and other greenhouse gases trapped underneath and contributing to climate change
- Temperatures in the Arctic Circle reached record highs within the past six months, only exacerbating the fires
- Human-caused climate change intensified these fires in a variety of ways
- We must act on climate change before other extreme weather events begin to seriously affect a greater number of humans

The scoop The price of crude oil plummeted following the outbreak of the novel COVID-19. As 2020 began, Brent crude oil - the global oil benchmark - cost $64/barrel. By April 21st, 2020, the price had dropped to $17/barrel. What happened?
Future of Oil
- The volatility and steep decline in oil prices may lead some producers to shut down operations. Shale oil extraction pioneer Chesapeake Energy recently declared bankruptcy. Many oil giants are delaying expansion projects.
- Investors are now less inclined to invest in oil & gas -- lower prices = greater risk, less profit. Energy was the worst performing sector in the S&P 500 index for four out of the last six years.
Environmental impact Climate awareness already poses a threat to Big Oil. With this economic crisis, investors might turn to renewable energy. Renewables are more price stable, cheap, and cost-competitive, even during low prices of oil.
Bottom Line It’s impossible to predict the future. Big Oil will certainly survive the pandemic, but its century-long domination of energy may soon end. One thing’s for sure -- clean technology has a strong outlook, and can certainly give oil and gas companies a run for their money. Not only from its greenness, but also in its economics.

The scoop Whales accumulate carbon throughout their lifetime and die with it on the ocean floor. So they save around 33 tons of carbon from the atmosphere each.
Why it matters Today, whales number approximately 1.3 million, and conservation efforts to return them to their 4-5 million pre-whaling population could significantly reduce the greenhouse effect by lowering atmospheric carbon dioxide. However, they are constantly at threat of being hunted.
Big picture Recovering the global whale population to even half its original size is no easy feat, but we must do all in our power to multiply whale species’ populations in all of Earth’s oceans. Regardless of whether a high-tech carbon sequestration tool becomes widely available, harnessing the carbon-capturing power of these beautiful creatures will always positively enhance our atmosphere and marine ecosystems.

The scoop John Tyson, Chairman of Tyson Foods, sent out a dire message about the global food chain supply breaking as millions of chickens, cattle and pigs face euthanasia due to widespread closures of slaughter houses.
Where it stands
- Meat processing plants across America face closure due to the pandemic.
- Processing plants use the ’just in time’ inventory system.
- Animals have limited processing time, after which they get too big and loses their monetary value for companies such as Tyson.
- It is difficult for meat processors to pivot between varying amounts of demand, exposing its shortcomings as a reliable form of food production.
What are the main concerns?
- Most meat processing plants operate in counties in America worst-hit by the coronavirus pandemic.
- Thousands of animals and workers in these poorly-sanitised plants remain in close proximity to one other.
- The chances of infections spreading are incredibly high in the plants, with over 5,000 meat workers and 1,500 workers contracting the virus since April.
- Meat processing systems lack a vital aspect of sustainability: resilience.
Zoom out Farmers have discarded millions of pounds of edible food due to the virus and warn of increased food security concerns. Almost 30-40% of food is wasted in America, equivalent to an estimated value of $162 billion every year.
Bottom Line Our food systems need to focus on resilience plans moving forward, making them more adaptable and decentralised to effectively deal with external disturbances such as a pandemic.

Big picture Did you know that 44 nations could disappear under the sea within your lifetime? Pacific Islanders face a desperate need for climate action.
What to know Back in 2017, I had the privilege to attend as a student observer at the United Nations Framework Convention on Climate Change (UNFCCC) International Conference of the Parties (COP 23) in Bonn, Germany.
The most striking presentation involved a group of representatives of the SIDS (small island developing states). The Pacific Climate Warriors spoke about the urgency of their daily and ever-present struggle against climate change.
A 2008 UN report found that the response of island nations to climate change is largely project-based, ad hoc, and heavily dependent on external resources. Australia and New Zealand have contributed financial support to adaptation efforts.
Bottom line For Pacific Islanders, climate action is more than just a school project, it is an existential threat.
