The right move for overfishing in Australia

English

In his article from The Guardian, Dermot O’Gorman, CEO of “World Wildlife Fund Australia”, wanted to share his successful projections concerning the problem of overfishing. Seeing, the urgent need in seafood business, the country decided to take actions into their own hands. Indeed, studies showed that a huge range of marine species were declining in numbers. Ocean ecosystems were in danger because of the overfishing and the dangerous fishing practices. As the demand in seafood increase, the offer is lowering rapidly.

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.

Singapore's Innovative Approach to Water Quality

English

In the article “Singapore Deploys Robot Swans to Monitor Pollution and Look Serene While Doing So” the writer presents a new innovative tactic the Singapore government has put into effect to test water quality. Peter Dockrill, the author of the article iterates how ultimately, the goal of the swan is to oversee the quality of their water bodies while being environmentally friendly and not disrupting species living in the water being analyzed. Dockrill mentions how amidst blending in seamlessly, the swanbots are also a more affordable option when testing water samples.

Gone Fishing And Climate Change

English

Compared to 1990, in 2011 there was an 60% increase in the amount of crustacean caught and represented the greatest growth in the fishing industry. This increase in caught shrimped has led to a huge increase in the amount of CO2 emitted by boats capturing crustacean, by about 28% between 1990 and 2011. This has been attributed to a decrease in the cost of gas. The catching of crustacean only accounts for 6% percent of tonnage by the fishing industry but emits  22% of all CO2 by the industry.

Causes of climate change 

 

Alaska + Warmer weather = More snow?

English

Warmer weather in South-central Alaska has been increasing the intensity of snowfall annually. In fact, data reveals that the quantity of snowfall has risen for more than 117% for the last 150 years in winter and increased by 49% during summer. On top of that, the state is among the ones experiencing the most of climate changes, having their average temperature increased by 2-3 degrees in the last half-century. Indeed, warmer weather gives us warmer air, which can contain more moisture than cold air.

The Big Thaw

English

In the article “The Big Thaw” by Daniel Glick, he reports that in the Glacier National Park in 1910 there were approximately 150 glaciers and now the amount has significantly decreased to less than 30 glaciers. And predicts that within 30 years they will all melt. Scientists have proof that the earth has rapidly been getting warmer, and the cause behind that would be human activity. The burning of fossil fuel and the growth of greenhouse gases in the atmosphere have affected the temperature of the earth.

Climate Change Cause and Effect

English

In the article “Climate Change Cause and Effect” by Joseph F. Doyle explains what humans that causes so many consequences. During 1950, the annual amount of carbon dioxide that was released in the air was around 9.2 billion tons. Nowadays, humans use 40.8 billion tons of carbon dioxide per year. In between Christmas 2017 and January 8, 2018, there was almost a new record made when it came to the amount of snowfall in North America. Other natural disasters such as strong hurricanes, wildfires, drought, hail, tornadoes and flooding have caused the U.S.
