Biodiversity is being threatened!

Recently in my Biology class one of the main topics has been the decrease in biodiversity and its causes. Habitat loss (which leads to a decrease in biodiversity)is accelerating at an alarming rate! One half of the world's original forests have been removed and at a rate ten times faster than they can be replenished. This fact coupled with the increasing number of invasive species, global warming, and the increase in agriculture have contributed to extinction rates of animals being ten to even a hundred times greater than in previous times of extinction. Many scientists believe we are currently living in the Anthropocene Era, which is the age of human dominance. As I briefly mentioned before hand, agriculture is growing at an alarming rate due to the continuous increase in the human population, between 10-15% of the Earth's surface is agriculture, this truth helps to explain why many species are going extinct or becoming extirpated, because agriculture is moving into these animals environments and destroying their habitats causing them to evacuate, or lose their lives.
