The facts are that everything is in a constant state of decay.  Man made things fail 100% of the time.  It only is a matter of time.  If we redirect oil coal and lumber industries money into helping the farmers grow and harvest these crops, our nation would grow by creating jobs on the farms, in the harvest, at the market, in industries created in textiles, medicine, renewable plastics, etc.  We could really put Main St. America back to work!  There are less than 200 pipeline inspectors for the entire United States. If we ran hemp fuel through the lines and through our cars and diesel engines, we would not pollute or rape the earth as we live here. We only borrow this earth from our grandchildren.
