Horses do emit "road apples," but those are at least biodegradable. And I suppose that's the thing -- the biosphere has evolved so that those waste products are not a problem. (Though, at equivalent rates of energy expenditure it would be a massive problem.)
So, maybe if we put a lot more pollution into the environment the biosphere will evolve to incorporate it into the "circle of life." Birds that absorb and digest soda-can retainers on contact? Animals that can't survive at temperatures less than 200 degrees F?
Better yet, why not spread radioactive material around and wait for the biosphere to adapt to that? That would remove the biggest obstacle against nuclear energy: fear of radioactive contamination. Cesium might become a human nutritional supplement.
(Note: none of the above suggestions are serious.)
Can things like solar & wind provide enough on their own, or is the only way out of the carbon-emission trap nuclear?
yes they can, if you use all of them combined, ie wind, solar, hydro(wave and dam), and have a way of storing the energy,
unfortunately the amount of resources it takes to get there would probably do more dammage than putting up a liquid thorium reactor in the first place.
