Consequences of fishing nets on Right whales

English

This article is written by Deborah Cramer and has as a goal to explain to the readers the negative effects fishermen have on Right whales when they leave their fishing nets laying anywhere around in the oceans.

The Plastic-Eating Enzyme that Can Save Oceans

English

Scientists have created a mutant enzyme capable of eating plastic bottles. This discovery is a major breakthrough for environmentalists since it could solve the global plastic pollution crisis. Initially, in 2016, a team of Japanese researchers found a specie of bacteria that can break down the molecular bonds of one of the most commonly used plastic in the world, polyethylene terephthalate,  also known as polyester or PET. Then, two years later, Prof John McGeehan, from the University of Portsmouth, UK, led a research on the enzyme produced by the plastic-eating bacteria.

Effects of Global Warming

The Great Wall of China ain't the only thing man mad visible from space

English

According to the article "The Global footprint of fisheries" by Julie Cohen, 55% of the world's waters are covered by fisheries. The Earth is composed of at least 70% water, so being able to cover 55% of that is staggeringly impressive (human greed is the best motivation afterall). UC Santa Barbara teamed up with prominent scientific figures such as Global Fishing Watch, National Geographic, Dalhousie University,Skytruth, Google, and Stanford University in order to accurately illuminate the world's global fishery net.

Arctic Ecosystem Under Threat

English

In his article “How disappearing sea ice has put Arctic ecosystem under threat”, Robin McKie warns that over two million square kilometres of midwinter sea ice have melted in less than forty years. Global warming, caused by excessive carbon emissions from cars and factories, is the main cause of sea ice loss. This deterioration of the Arctic natural ecosystem is seriously endangering many species like seals, fish, polar bears, foxes, and wolves since according to the marine ecologist Tom Brown, the Arctic food chain depends on a stable sea ice platform to survive.

How Human Activities Affect the Ecosystem
