One writer was Henry Miller.
Both the maple syrup industry and the peach growing industry are
dependent on their respective natural environments owing to the fact
that without the appropriate natural environment, you would run the
serious risk of not being able to grow maple trees or peach trees.
In either event, you would be forced to retire to your corporate headquarters
in Yerington, and switch to selling shoes made in China.
Water cycle is effected by pollution, whether it is water pollution or air pollution. Air is polluted by Suspended Particulate Matter and by different harmful gases like Sulphur dioxide etc. These gases react with water vapours in the sky, making the water in the clouds acidic. This acid falls as rain water causing acid rains. This acid falls in ponds, on land, in fields, causing harm to us and to the crops as well as to the fishes or creatures in water. When the water evaporates from ponds, rivers and oceans to make water vapour, the the water in these water bodies becomes more acidic, and again when acid rains occur, this acid again mixes with the water of the water bodies, which already has acid, causing the water to become more concentrated.
I think earthquakes or volcanoes.
