Which human activity has probably contributed most to the acidification in the adirondack region of new york state?

The burning of fossil fuels in order to produce energy to manufacture various goods is the human activity that has probably contributed most to the acidification in the Adirondack region of the New York state.

Explanation:

The Adirondack Mountains and the surrounding regions lie within close proximity to the highly industrialized areas of the United States and Canada. The manufacturing industries in Montreal (a Canadian city very close to the Adirondack region) consist of the aerospace industry, electronic goods, pharmaceuticals, printed goods, textile and apparel, etc. These industries use fossil fuels to produce high amounts of energy. Burning of these fuels emits pollutants like sulfur dioxide and carbon monoxide which rise high up in the atmosphere and mix with the clouds and cause acid rains.
