One thing about wind generation has been bothering me for a while...

Wind generation extracts energy from the wind. It's not an issue at the level it's happening presently (the first oil wells were a ho-hum thing too) but is anyone giving thought to the effect(s) of decreasing air flow? It's not a world wide issue but even local effects could be serious. Less wind in a valley that houses agriculture could lower yields and that could lead to downstream effects. Similar with the dispersal of plant seed, etc..

The other thing that bothers me about all this tree-hugging is the fact that nobody talks about the real problem. We're rapidly approaching the maximum population that the planet can sustain and yet there are large groups that are reproducing full speed with no plans in place to even approach zero population growth. (Malthus was more than an old British pessimist.) If we wait for nature to correct this problem, it will be terrifying; famine and war are very messy.
