?What causes water shortage

Human population is very successful in controlling the water and was able to form civic life and urban water management and to satisfy their needs. The natural water systems are increasingly under pressure and some rivers, lakes and watersheds are running dry. But what are the reasons causing water shortages?

• Pollution

Various factors such as water pollution from fertilizers and pesticides from agricultural lands are transferred to water and waste and industrial waste arises. Even groundwater contamination are not exempt from this because some of these contaminants can leak into the depths of the earth.

Some of these contaminants impact immediately on leaving the water, such as human waste contains bacteria that infect the water immediately.

• Agriculture

70% of available water is used for human consumption in agriculture! This causes the drying of rivers and lakes. Many countries that are engaged in a massive scale food production, such as India, Australia, China, Spain and America have a shortage of water to the red line. Besides agricultural waste water, fertilizers and chemicals, it also gets contaminated.

• Population growth

In 50 years, the world population has more than doubled. The rapid population growth and economic growth and industrialization, ponds around the world has changed, leading to a drastic reduction of species diversity has been.

• Climate Change

The human production of carbon dioxide and other greenhouse gases in the atmosphere continue, conditions and weather patterns will change the world. Will occur in some areas, droughts and floods in some areas, this will be devastating. In some parts of the mountains of ice and snow will be wines.

These changes will intersect with each other and lead to water shortages for agriculture, energy, ecosystems and urban living will.
