Same old shit would be what we are doing now so no. It's really not as big as you think Brutal.
Plant a garden in your backyard
Don't have a back yard, the government stole the money I could have used to buy a house and has given it to some one else that bought a house despite having suffered the same problem that I suffered (The government stealing the money they could have used to buy a house.)
, source food locally,
It doesn't matter where Food comes from, and the logic behind this "solution" is that CO2 released by the usage of Fossil Fuels somehow harms the environment despite the fact that PLANTS use CO2 to survive and produce energy.
promote diversity in natural ecosystems,
Ecosystems, with the exception of the rain forest, tend not to be very diverse. A forest in one area may have a niche exploited by one species, that it would not be able to exploit in another.
Or at its worse this would mean bringing invasive species to new ecosystems, which was done and caused problems.
make better use of available rainwater.
Plenty of rain water, it's in the oceans, desalify it, and pipe it.
Or, perhaps, if I still lived in the South West my answer would be, WHAT RAIN WATER?
The energy savings from doing this alone are immense.
Energy is not a fixed value, there's plenty of energy out there, energy is not the issue, producing enough is. The best way to produce enough is Nuclear Fission, or actually financing more experimentation into Nuclear Fusion instead of subsidizing Solar and Wind, and BioFuels, esp. Ethanol.
The other benefit of something like a food forest over conventional agriculture is the amount of labor required to maintain it is next to none.
The problem is that I don't want a damn garden in my yard when I have a house. I bought the house for the aesthetic appeal of having a nice green lawn.
Cities can still exist we can still build your space stations as well.
No, because all this worrying about problems guarantees a waste of funds by trying to solve these so called "problems" in the same old way, or in even worse ways.
Rooftop surfaces should all be planted, horizontal surfaces utilized as well.
Has anyone told you about New Mexico where Martin Chavez (Mayor, D, Albuquerque) tried to state that everyone must grow grass on their roofs and not in their yards, which must be xeroscaped?
The benefits to all this are huge and in fact are really close to your political beliefs of being self sustainable.
I have no political beliefs of being self-sustainable, my only political belief is that Government is a parasite that should be destroyed.
I think you just like to argue . . .
Yes, Arguing is a great way to relieve stress, gets all those nasty emotions out of the system.
The plan is NOT to lose 90% of the populace
