Our childern are fucked if WE don't act to change some fundamental ways of living. We don't have to give up all aspects of our modern living, but we have to stop treating the planet's limited resources as if they are limitless...right now. The global 'free' market isn't set up to do this, rather, it's set up to exploit. Meanwhile, we sit around and listen to blabbering politicians who believe that Noah's Ark is a fact and that Darwin was a heretic.
We need to act now on a large scale. This isn't just about avoiding meat, or recycling, or driving a fuel efficient car (even though all of those help). The global economic system doesn't punish CO2 polluters and doesn't reward CO2 eliminators. In the US, most of our electricity comes from coal, the dirtiest fuel. We have to stop that now and yet there isn't an economic incentive to make it happen. (Note: When you hear people talk about clean coal, they're talking about reducing heavy metals and sulphur emissions, not CO2.) Coal is the worst fuel.
China is building 1 large coal fired electric plant per month to sustain their economic growth. No matter how much we recycle, it's hard to offset that scale of CO2 emissions growth and the Chinese aren't going to stop building these power plants any time soon.
Meanwhile, the fossil fuel corporations spend about $150,000,000 per year to convince us that manmade warming is a theory and clean coal is real. The alternative energy research funding in the US is largely controlled by the US Department of Energy which historically is more interested in building nuclear bombs than solving our energy problems.
We have a way out of this mess which is to massively invest in solar power. The goal should be to develop solar power systems that produce energy at a lower cost than coal. If it has to include subsidies to get started, fine. The energy from the sun exists. We could put people back to work and also provide a future. It's a hard, expensive project but a challange to save humanity is a good thing. It sure is better than fighting endless war. But, we don't have the will. Someone has convinced us that fighting endless wars over increasingly scarcer resources is a better path. WTF?
So sorry to rant on like this. I'm done now.
