Which of the following threats to biodiversity is a result of cutting down forests? (4 points)
Maslowich

Answer:

Explanation:

When I was growing up, one of the most popular cartoons was a little possum whose name was Pogo. He often said

“We have met the enemy and he is us.”

It is something Pogo said more than once. We are the problem with biodiversity being threatened.

We clear land for agriculture, not only in Canada and the United States, but in places like Brazil where it matters what is done to the environment. Those trees are the planet's lungs. Whole environmental groups are devoted to stopping the harvesting of trees that are hundreds of years old.

Our oceans have become cesspools of plastic.

Our rivers have become dumping grounds for all kinds of pollutants like paint and car tires to name just a couple.

Our landscape has been cluttered by billboards advertising things that are hundreds of miles away.

There's mining, oil, and other industries that make Mother Nature shudder every time they come near her.
