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.
The snakes are an invasive species. They have no predators in this ecosystem, so they have nothing to inhibit the growth of their population. They eat the native creatures and begin destroying the ecosystem.
The geography of Afghanistan made it easy for our soldiers to blend in with their uniforms making it difficult to invade if you can' see who your fighting.
