Plants - the lungs of the earth
Plants are the lungs of the earth and of people. Without them we could not live and one could not imagine life on earth.
What would interest me:
How can you get people to cut down no trees or only a few?
What happens if we have too few trees in the world?
Are there alternatives?
Is it possible to produce oxygen in other ways without anyone suffering any damage?
Are there already signs that we have too little green space?
(in process)
