I agree. However the thought that usually humanity, when cornered, always finds a way reassures me.

Just think of the problem of the hole in the ozone: due to our activity (meaning the entirety of the industrialized countries) a problem has arisen which, if not solved immediately, would have brought catastrophic and irreversible consequences for all of us.

An effort was needed on the part of all the nations together to find a solution and start solving the problem and today, after almost fifty years, we can say that we have succeeded.
