The government has an abysmal record on these issues. Throwing money at a problem that is world wide not just the US. The Government needs to enforce the regulations they have and strengthen them where necessary . Stimulate the economy by making companies like GM that we bailed out give the money back + interest. And tax every vehicle they make outside the US at a rate enough to pay for all the unemployed workers they are creating by closing plants here and opening up across the border and manufacturing any where else.
