Remember the forests.

Rainforest Concern is a Registered Charity in the UK, established to protect threatened natural habitats and the biodiversity they contain, together with the indigenous people who still depend on them for survival.
The world's tropical rainforests are the richest and most diverse habitats on earth. They represent a vast reservoir of knowledge and contain a wealth of ecosystems and wildlife, with many species still undiscovered.
I believe destroying the forests as they are is a huge mistake and could bring huge problems,there is concern about medicines that are being destroyed, animal life,and the people of the forest there lives being changed not perhaps for the best. The trees clean the air we breath and cause a coolling system and control over the earths humitity, we talk of climate change the amount of destruction here will cause much more.
Help if you can,you can buy small plots of the land to prevent it being destroyed or huge plots if you have the money,it would be money well spent.
