What is the norris-la guardia act of 1932?

The Norris-La Guardia Act of 1932 was a federal law of the United States that prohibited yellow-dog contracts, banned the federal court from issuing injunctions against nonviolent labor disputes and created a positive right of non-interference by employers against workers that are joining trade unions. I hope this helps.  

Reduced dependence on nonrenewable resources
Our dependence on fossil fuels has actually increased dramatically as more and more people own vehicles. Vehicles are becoming more efficient, but with so many on the road at once, we're burning through our nonrenewable resources fast. It may not happen on our lifetimes, but we'll run out eventually and unless we find a better source of energy by then, we'll be in a bad situation.
