Now listen to part of a lecture on this topic in an environmental science class.

So, one example of this is the macaw, the great green macaw. Now, the great green macaw is a beautiful bird, a fairly large-sized parrot known for its colorful feathers, gorgeous green feathers with some read and blue feathers, too. The macaw lives in the South American rainforest, in a part of the rainforest where a lot of trees have been cut down, trees that the macaw relies on for its food and nesting. So, the macaw was in trouble.

And, of course, along with the trees, a lot of other animals were in trouble, too. Lots of birds, bats, and frogs also live in these trees. So, when the trees were cut down and cleared away, these animals also didn’t have a place to live anymore and their populations drastically declined. So, what a concerned group of people in the area did was they started spreading the word about how the macaw, you know this really beautiful bird, needed help.

They made little books with information about the macaw, with pictures, full colored pictures of the macaw that showed off its beautiful feathers, and they passed out these little books, these informational brochures. They distributed them to people in schools and community centers in the area. And a lot of people responded. They contributed money, and helped the group set up some protected land, a special area where no one could cut down the trees, so the macaw would be safe. And the macaw’s population started to increase and other birds and bats and frogs came back to the area, too. Their numbers increased along with the trees.
