What do you think this script is about judging from the title and the pictures
I think the script "The Amazon rainforest: a natural treasure " is about the Amazon jungle and the plants and animals found there. They are all natural treasures because they are valuable to the Amazon. The pictures show that the plants and animals living in the Amazon rainforest are unusual and beautiful. There are different kinds of animals that depend on the rainforest for shelter and food.
