Water is one of the most precious resources. The more we develop our land and increase infrastructure by building roads and developing towns, the bigger the human effect is on the water cycle.
I. Increase in population: When our population grows, there are many human actions that we do such as use water to produce electricity, irrigation, and other agricultural work all of these activities disturbed the cycle.
II. Increased used of use of toxic chemicals in the agriculture, and manufacturing industries, as well as the runoff from chemical fertilisers and pesticides, these are polluting our surface water as well as contaminate our ground soil, making crop production difficult.
III. Cutting of trees on the large scale is called deforestation. Deforestation affects water cycle in two ways, first it increases the carbon dioxide in the atmosphere causing global warming. Secondly, less tree, do less transpiration which causes less rainfall.
