ONE of the reasons that we pay farmers NOT to grow is to stop the land from wearing out, losing to many minerals etc. ANOTHER reason is the lose of critical wildlife habitat. Prarie pot holes, wet prarie, marginal wet lands to name a few. Another is CLEANER water. One way to perk up worn out land is to fertilize it. Those fertilizers get into the rivers and lakes. They cause alge's to grow at above normal rates. That removes oxygen from the water causing fish to die and water to turn bad increasing the cost to making it safe for drinking. There is NO easy answer. Coal CAN be cleaned up. It costs money too. The answer lies in many old and new remidies.
Drill in the U.S. for our own oil, fuel cells, fuels from coal, public transportation, more use of rail, etc, etc, etc. We have to take a bit of time, DO NOT rush into one answer, that is how we got to where we are today. WHEW, said may piece!!! My spelling sucks to say the least, but you get the idea. REMEMBER, EVERYTHING we try will cost more. What costs we chose to pay is the problem, more per gallon, dirty water, less wildlife habitat. We WILL pay, let's try to do it smart this time. Layoutshooter
