Blog #5

Blog #5 There have been 5 major extinction events throughout history, are humans impacting the 6th? Why or why not?


Humans are impacting the sixth major extinction because we are the direct cause of destruction to the ecosystem and species. By transforming landscapes, introducing alien species, polluting the environment, and exploiting animals we are hurting the environment and the animals. Humans cause animals to go extinct by overhunting them and possible spreading disease-ridden organisms. Also, since the human population is growing, we clear lands to help feed the new generations and spread agriculture through higher fossil energy, therefore modifying the environment more.
