In the article "Sustainable seafood farms can help Asia's oceans" by Mata Press Service, the main purpose is to show how overfishing and destructive fishing in Southeast Asia puts its sustained existence at risk, despite the diversity of the marine ecosystem. The resource base of fisheries is at a medium to high risk of overfishing in the future, as the UN reports the extinction of exploitable fish stocks by year 2048 which is an economical consequence that also affects seafood production and needs.

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.

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.

In her article “Climate Scientists Debate a Flaw in the Paris Climate Agreement”, Dana Nuccitelli reports that climate scientists remain skeptical about the Paris climate agreement to limit global warming to 1.5°C above pre-industrial temperatures. The 1.5°C target was initially measured by Richard Millar from the University of Exeter who used the the Hadley Centre global surface temperature dataset called HadCRUT4.

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.

The sole purpose of the article “Marine Ecosystems Are Preparing for Climate Change” written by Kavya Balaraman is to explain to us how resilient our marine ecosystem is despite the effects of climate change. The main issue of changes on the marine ecosystem is mainly due to pollution and climate changing. The main points the author of this article uses to explain how damaging climate change, is with the use of researches done by scientists that show the resilience of oceanic life to pollution and their ability to regenerate themselves.

The article “How Many People is Too Many People?” by Hannah Gais inform us about the danger of outstripping resources with our growing population and gives solutions to prevent this problem. According to the U.S. Census Bureau, the main cause of resources depletion is the outgoing expansion of the population. Consequently, since the world population is estimated to be 11 billion at the end of the century according to United Nations, Natural resources will be insufficient for the number of people living.

In his article “Wealth redistribution and population management are the only logical way forward”, William E Rees warns his readers that our techno-industrial society is running on an human ecological footprint that is at least 60% larger than the planet can sustain. While countries are still using renewable resources at a faster rate than they can replenish, the world community still has not agreed on a response to this issue.
