Clear air and water

As coal and oil are being replaced by natural gas, the people in the US are enjoying the benefits of cleaner air. Meanwhile coal exports to Asia and Africa have increased dramatically and imports of rare earth metals have helped to grow the solar and wind industries. Mining these metals creates an environmental nightmare for China adding ground and water pollution to their already poisoned air. Wonder what the chances of getting a government grant to write about the advanced nations once again taking advantage of third world countries.
