i guess so..but i was talking globally: planting trees doesn't sound efficient (at least in rural areas): it eats up fertile land and fresh water that could otherwise be used to grow crops or feed fresh water to humans. wind farms and solar should also be installed offshore to avoid wasting fertile land. also europe could use interconnectors to help transfer excessive energy produced by renewable between its countries to mitigate production intermitancy. extra urban estate should be dedicated for social housing or, ofc planting trees (if water reserves allow it)(china could afford planting extra trees, but europe can't afford that luxury for now and should implement social housing instead)(poorer countries are lightyears behind both europe and china, and china ofc leads the pack)
