Humans are responsible for other species' extinction because over the years we have overhunted them, such as was the case of the Tanzania tiger (Thylacinus cynocephalus), and destroyed species' habitats. We have caused climate change and air and water pollution, such as happened with the industrial revolution and still with many of our today's industrial practices.
So the correct answer is the first one: A. I, III, IV, V, or destruction of habitats, pollution, overhunting, and climate change.
