The tree planting idea could use more money from somewhere, I mean; if only a few well-off people (like I'm trying to create a dark, wet little forest (I use trees and plants that use very little water; I already have spots that have climbing plants over trees which are much cooler in the hot summers + hold dampness after watering much much longer than the rest) in a very arid part of Spain on my own dime, but I have the land and money to do that) do it, it won't help at all (besides other people thinking; crazy foreigners planting useless aka fruitless trees!). For most people it's simplistic but not feasible; however, if you would state sponsor the farmers here to plant trees between their fruit trees, it would fill entire south of Spain in no-time as fruit simply does not make that much and it doesn't make for 'forest' material, but they plant nothing else than the basic necessary trees to get fruit (and cut + replant years later if another fruit makes more money, which is really horrible to see, especially with older olive trees), which simply is not enough. The entire coast here would be forest, now only a sliver is left; everything was cut and used to fuel steam boats. But we know it's possible, just no-one wants to invest in it. I guess that's the case in many parts of the world. I think both ideas are kind of 'simplistic' in a way; the one because theoretically anyone can plant trees and so people think ; 'that's a solution! let the state/others do it!'. Which makes sense; that's what taxes could be used for and billionaires can sink their philanthropy money into. And the other is 'let's just bugger off this planet before it dies and reboot on Mars! Let the state/others do it!'. And both will give way to what you say; planting trees or going to Mars probably will give people the idea that now it's solved so we can just do whatever. I mean; I hear it from people with gas(well, Diesel)-guzzlers already; a lot of energy is from renewables and many cars don't polite as much / are electric, so 'my car is fine, the rest is compensating for it'. We need people tinkering with several things; actually with some different perspectives; a) making renewables even more effective b) getting us off the surface of the planet if/when we need to (Mars, computer brain upload, brains in vats, whatever) c) try to cure the earth and it's atmosphere. We need smart people and a lot of money to do these things, as none of them will 'just' work or be enough to fix everything fast enough. Problem is, we are, as humanity, not nearly focused enough of any of them. In movies (funnily enough, usually in heavily Chinese invested Hollywood movies) you always see that we need a common enemy bent on our destruction to unite humanity. We have one, but the uniting isn't happening; I guess it's not in-your-face enough yet.
