Extinction is a natural part of life on Earth. During the history of life on Earth most of the species that ever existed have ev
olved and then gradually went extinct. Species go extinct because of natural shifts in the environment that take place over long periods of time, such as climate change due to an ice age. Today, species are going extinct at an accelerated and dangerous rate, because of non-natural environmental changes caused by human activities. Which would not be considered a human activity contributing to the loss of biodiversity on Earth? A) habitat loss B) asteroid impact C) over exploitation D) impact of non-native species
