In the quest to make the world more conducive for living we are destroying it the more. In Nigeria presently the price of crude oil by product is on the high side which has caused hardship for people as you have mentioned it. The painful part about some of the things you have mentioned can be avoided with good advice but people won't follow it has long as it does not affect them directed.
I'm definitely worried about countries that are really close to the equator and therefore more likely to be getting hotter and suffer more droughts in the coming decades. I think the people of Nigeria need solar systems desperately, but from what I understand they are expensive and hard to get.
