Second thoughts:
I don't think doing anything in the future will be of use, because we should have already done it, and we didn't, so we have to do it now. 
And what we should do is:
To find and actually use and apply new energy sources.
To do more (or less, depending on what the problem is).
To clean the mess we have done / recover the gap in the ozone layer /fix the damage that we have caused.
If you're interested:
I don't think protesting (like we're currently doing) will be of help for two simple reasons:
1. - I don't know for sure, but I don't think politicians care, like or pay attention to protests (unless it's something like the Yellow Jackets).
2. - The time we spend protesting is more valuable than we think. We should leave that aside.
Hope it helped,
