Digging up New Problems
A new natural resource, coal, was discovered in Pennsylvania.
Coal mining was a way of life for immigrants and their future
generations. But, as with anything in life, if people don’t
exercise moderation the balance of nature is disrupted. On January
22, 1959, the Susquehanna River collapsed onto the Knox coal
mine. People died and thousands of lives changed in an instant.
Another environmental problem caused by the coal industry is
acid mine drainage. It's the single largest source of water
pollution in the state and in the Chesapeake Bay.
