Water is our lifeblood
Water is the most
precious natural resource of the world. It covers 70% of the earth’s surface.
But most of them are oceans and seas. Some are frozen ice caps. Fresh water is
only about 3% of the earth’s water.
Water is
essential for our life. Water quench the thirst of human as well as animals. We
are unable to live without water. Water is useful in various ways. Water is
used for cultivations. People grow grains, fruits, vegetables, flower and
herbal plants using water. We need water for domestic purposes such as cooking,
cleaning and washing. Without water we can’t do any industry. Water helps
transportation too. Rain water and ground water helps to maintain forests.
Increasing
population and expanding of cities and villages make water ways pollute. People
throw garbage into rivers, cannels and lakes. Rapid industrialization makes
water polluted with chemicals such as chromium, lead, iron
and rust. Using fertilizers, weedicides and insecticides in paddy
cultivation pollute underground water resources with various pollutant such as arsenic,
urea, ammonia and phosphate. In the other hand people waste
water. They open taps and let water run and don’t close it properly. In this
way pure water is becoming scares.
