Both your points are valid and should be addressed. For the most part they have been in developed countries, though there is still room for improvement. However, the "cure" for the global warming "crisis" is to increase the cost of emitting CO2. This doesn't address the items you brought up, it only makes existence for most of the world's population that much harder.
I'm all for alternative fuels whether they are carbon based like natural gas or biofuels, or non-carbon based like nuclear, wind, hydro, geothermal, H2, or solar. But all these alternatives have their drawbacks (as do coal and oil) and will take a long time to implement effectively. Why must we tie one hand behind our back with inane and expensive carbon taxing and trading schemes while we seek alternative answers?
Also, the main groups in opposition to creating alternative energy sources are environmental groups. According to them:
You can't drill for natural gas because it will destroy habitat and poison the seas.
You can't create biofuels because the increased agricultural production destroys habitat (it also drives up the cost of food).
No nuclear because of the radioactive waste, plus a reactor could blow!
Wind turbines kill migrating birds and ruin the view.
Hydro dams destroy habitat.
Solar panel farms require a lot of area, again destroying habitat.
H2 destroys habitat indirectly because the energy needed to create it has to come from somewhere.
I haven't heard any complaints about geothermal - yet.
The environmentalists complain that man is destroying the earth, but don't want us to solve the problems they say exist.
