History
Deforestation
In 1847, George Perkins Marsh delivered a now well-known speech in 1847 to the Agricultural Society of Rutland, Vermont, in which he claimed that
“Climate itself has in many instances been gradually changed and ameliorated or deteriorated by human action... the draining of swamps and the clearing of forests perceptibly effect the evaporation from the earth, and of course the mean quantity of moisture suspended in the air. The same causes modify the electrical condition of the atmosphere and the power of the surface to reflect, absorb and radiate the rays of the sun, and consequently influence the distribution of light and heat, and the force and direction of the winds” [1]
