Article Summary

The acid rain was killing maple trees in a forest in New Hampshire. The acids swiped down to the soil taking out nutrients of the trees. The trees got very wick and they catch an infection or a disease, and then lead them to death. This started around 1980. This was a big problem because all about the maple was a big business. Fortunately on 1999 they sent a helicopter to spray nutrients all around the forest. After 5 to 10 years scientists discovered that the soil was in a much more acceptable level for the trees to live.
