According to the article “Future fisheries can expect $10 billion revenue loss due to climate change” climate change has an influence on many high points.

In the article "Fishing problems: poor fisheries management," it explains the problems that are going on in oceans and fisheries and what their main causes and affects are. Oceans are also threatened by marine plastic pollution and each year, an estimated 8 million tons of plastic enter the oceans, with microplastics becoming part of the food chain. Scientists estimate that without urgent action, there could be more plastic than fish in the ocean by 2050.  While complex, the issue of ocean plastic waste is a solvable challenge.

In the article "Evaluation of climate models using paleoclimactic data" it explains how in this period it is the warmest periord in modern civilization, and this trend is expected to continue over time. The climate over the last few years have been record breaking, the last 3 years have been the warmest years on record for the globe. Evidece has shown that it is most likely due to human activities, such as emissions of greenhouse gases. They have susposedly been the number one cause of climate arding since the mid 20th century.

According to the article “Population Growth Puts Dent in Natural Resources”, population growth will exhaust all the natural resources. One of them will be water and energy. And since only the USA has 305 million people from 6,7 billion, it should be taking seriously to take action towards this critical situation. Criss is one of the researches that is working with his associates to combine as much data on the environment.  Due to his research, he found that around 150 million Americans use nonrenewable ground water everyday.
