Describe the sixth mass extinction event, when it occurred, and its specific causes
What will be an ideal response?
Currently, most biologists believe that Earth is now in the throes of its sixth mass extinction event and that we are the cause. The changes to Earth's environment by human population growth, resource use, and development have greatly altered conditions for many species, have driven many to extinction already, and are threatening countless more. The alteration and outright destruction of natural habitats, the hunting and harvesting of species, pollution and the introduction of invasive species from one place to another have contributed to the threat to Earth's biodiversity.
