We know that the earth is warming and so is the ocean. But human green house gases comprise only 7% of all green hoie gases released. Sure we need to reduce burning of contributing fuels and modify human commercial processes.  Methane from cows and their excrement are major contributors of a green hjousegas. lets kill all cows then uphs what would r3place that portion of the human diet.
Lets do what Vermont has done and build wind turbines. But in just one wind farm in Northern Calif. there were over 1,300  birds of prey including 75 golden eagles and 100s of hawks. Any other energy wind source killing this many birds would cause an enviro uprising. Oh yes, howabout all those ugly windmills covcering the glorious hills and deserts of california.
Also lets move ethanol. By the best estimates for every 100 gals of ethanol it takes 80 gals of fuel to profuce it. The production of fertilizer, fuel for the farm tracotrs and the distilling process eat all that energy up. An acre of farm land produces 300 gals of ethanol. So each acre produces a net 60 gals of ethanol. That's one barrel of oil for each acre. per year. The new oil well in the Gulf is producing 6,000 barrels a day that's 2.2 mil barrels a year. So for ethanol to equal just one oil well it would take the use of million acres to equal the production of one oil well.
And the cleanest fuel is nuclear but what grister would want that.
