In physical geography, the term "Hydrospehere" ( Greek hydro means "water" ) describes the collective mass of water found on, under, and over a planet's surface. The Earth's hydrosphere consists chiefly the oceans, but technically includes clouds, inlands seas, lakes, rivers,, and undergroundwaters. The earth's appears to be a blue planet when seen from outer space. this is because more than two-thirds of the Earth's surface is water. We call this the hydrosphere. (www.newworldencyclopedia.org)

The hydrosphere is important for many reason. It is essential to life. Neither plants nor animals can live without it. It provides the water that is needed by all living things. Not only do we drink water but we also use fresh water to irrigate the land. This enable us to grow food without having to rely on rain and we can grow more food this way. Oceans, lakes and rivers are themselves important sources of food. Fish is the major source of protein for many people around the world, and much of our salt comes from the sea, and this help flavor our food and also important natural preservatives.
Even though we often perceived water to be very ordinary, we are dependent of water for survival. We use water for different activities like washing our clothes, cleaning, bathing and cooking. We are about two-thirds of water ourselves and require water to live. Life as we know it could not have been evolved without water and dies without it.

We should protect our hydrosphere in order for us to have a good source of water to drink and good source of food from our oceans and rivers. Neglecting the importance of hydrosphere can lead to water shortage and we humans will suffer and face the consequences of not taking care of our water resources.
