I think it's right when they say each one of us should aim to plant one hundred trees during our lifetime. I think the world would be better with more forests!
Our planet is in trouble, more specifically all that live on the planet. Even if we choke off all life, the planet is likely to survive. But with no humans living, what good is that? We are already seeing illness that We never saw or in areas it never was seen. Shame on us for not protecting the world.
