Global Post


For this blog I wrote about the environmental aspect of a global issue. I found a website that had all different types of environmental factors leading to the issue. One of the issues was biodiversity, and how human activity is causing mass extinctions from animals, to forests, to whole ecosystems. The World Resources Institute found a link between climate change and biodiversity. A type of ecosystem that has been neglected, and is one of the richest in biodiversity, is the coral reefs in the world. Twenty percent of the coral reefs have been destroyed and show no prospects of recovering. Many scientists have concluded that climate change may be one of the greatest threats facing the planet. With global warming on the increase and species and their habitats on the decrease, chances for ecosystems to adapt naturally are diminishing. Research has shown that air pollutants from fossil fuel use make clouds reflect more of the sun’s rays back into space. This leads to an effect known as global dimming whereby less heat and energy reaches the earth.
