The main reason FOR exploiting a tropical rainforest would be the products we get out of it -> pretty orchids for our gardens, the products of plants that can be used as food or medice (1/4 of all medicine comes from the rainforests), the exotic animals, the timber than ccan be used for building, etc.
They have created agencies. Those agencies created rules and regulations to stop the flow of pollution, etc.
Rocks are broken down into smaller pieces by the process of weathering and erosion.
Hope this Helps!
