During environmental science, many topics have been highlighted on the current situation of our environment and of our world. The media were also able to clearly develop the subject. Four selected news articles include the effects of human population on animals, issues with fracking, Environmental Protection Agency ozone and pollution standards, and issues linked to certain clean energy sources, such as geothermal energy.

Get the original essay “Humans have caused 322 animal extinctions over the past 500 years” provides a stark primer on the effects of human population; Over the past 500 years, humans have managed to cause the extinction of more than 300 animal species. Most of the extinctions took place in the last two centuries, around the same time as the start of the industrial revolution. The article goes on to state that by 2100, the human population on earth would have reached a staggering 27 billion, more than three times the current population. Many scientists have expressed concern about these findings, going on to argue that "animals matter to humans, but [on the scale] they matter less than food, jobs, energy, money and development” (Galetti 1).

Unfortunately, local communities around fracking areas have had their water supplies contaminated, causing pumps in the area to shut down. Various members of Congress and environmentalists have fought over the issue. Governor Hickenlooper of Colorado said, “We have an obligation to develop energy in a way that is safe for our residents…and that protects our health and our environment. » Many residents have expressed concerns about fracking in their communities and hopefully fracking companies can negotiate and settle in order to protect their environment.

In the article "EPA's New Ozone Standards and the Case for Optimal Pollution," the EPA's proposal to reduce parts per billion of ozone pollution in the Atmosphere could cost Americans a hefty sum of about $270 billion a year, with the potential for millions of people out of work and higher energy prices.
