I will feel a lot better about people preaching conservation when they can add population stabilization to their words. As long as population increases, population growth will eventually negate any reduction in consumption brought about by conservation.
Heard an NPR piece over the weekend that talked about Connecticut's garbage collection. They have landfills in the state (I think they said that) but they send 400,000 tons of garbase out of the state each year to be landfilled in Ohio, Massachusetts and New York. They have a recycling program which saves some percentage of their garbage from having to be landfilled. However, the Connecticut government employee involved in Waste Disposal said said that they hoped to double the amount of recycling they were doing. But then he added (and as per usual, not denouncing the fact) that they would need this increase in recycling just to keep their landfilling constant due to the fact that both consumption and population were increasing.
