animals (especially ones at sea) can get caught up in this trash and die or mistake it as food and eat this trash or plastic. the ocean right now has five texas state size balls of plastic floating in the ocean which kills sooooo many sea creatures
2.poaching
poaching animals causes animals to die faster in their natural environment which means their population declines quicker. many animals such as elephants are under the endangered species list, due to poaching.
3. human touch
the amount of people we have on this earth is was more than it used to be which means we need more space for buildings and homes. when there is an empty space, we build. this empty space could’ve belonged to many animals and we just took their home from them.
