In this article, “Getting Serious about Overfishing” by the Economist, it is implied that our oceans are in more trouble than they have ever been. According to the article, we consume the most fish we have ever consumed. It is shown that in a study conducted in 2013, 32% of the world’s fish stocks were being exploited beyond their sustainable limit which is a lot and this is an increase of 10% since the 1970s. Although we overfish, other problems which affect the oceans are pollution and fertilizer run-off which causes big damage to the fish since it ruins their ecosystems.

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.

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.

The article "Warm water rapidly melting Antarctica from below due to climate change"  by the science correspondent Josh Gabsatiss, explains how climate change creates tremendous warm underwater that melts Antarctica's ice sheets, resulting in a rise of sea level which is estimated to highly threaten humankind due to possible natural disasters. It is also crucial to find the quantity of melted water expected to increase in order to be able to map the retreat of grounding lines, since the ice shelves connected to the bedrock underneath may collapse.

In the article "Humans changed the ecosystems of Central Africa more than 2,600 years ago" published in Science Daily, the main purpose reflects on the real cause of the rainforest crisis in southern Cameroon, which was assumed to be a result of climate change (decrease in precipitation amount, increase in precipitation seasonality) , but new controversies claim that the actual cause was humankind.

In the article ‟Humans causing catastrophic ecosystems shifts, study finds”, the author, Thomson Reuters, discusses that human dominance over the natural environment has caused many changes in world ecosystems. Human activities have a devastating impact on ecosystems. As the author mentioned, the damage and exploitation of wildlife and natural vegetation by human beings has left ecosystems in bad shape. Unfortunately, at least 468 creatures have been eliminated from the planet since 1990, including the Costa Rican golden and Yangtze.

The article "Businessman plans to burn 'body parts and organs' to create energy' by Victoria Ward has for objective to show a new way of creating energy by using a different process than incinerators. Waste would be exploited with a gasification process resulting in a synthetic gas generating thermal energy (combination of plastic and biomass). The main cause of the issue is to find a cleaner way of combustion for the environment when producing energy. The author points out that it is a better technology, with better quality fuel than the large incineration companies.
