what are the different causes of water scarcity
Answers
Causes of Water Scarcity
Water Pollution
Water pollution is yet another cause of water scarcity. The sources of water pollution include pesticides and fertilizers that wash away from farms, industrial and human waste that is directly dumped into rivers without treating it in water treatment plant. Oil spill on the ground, waste water leakage from landfills can seep underground and may pollute the groundwater making it unfit for human consumption.
Overpopulation
The rapid increase in human population combined by massive growth in industry sector have have transformed water ecosystems and resulted in loss of biodiversity. As population is increasing at an ever increasing rate, the demand for new resources will result in additional pressure on freshwater sources.
Agriculture
Agriculture uses majority of available freshwater. The sad thing is that about 60% of this water gets wasted due to inefficient agriculture methods and leaky irrigation systems. In addition to this, pesticides and fertilizers are washed away in rivers and lakes that further affect human and animal population.
