HYDROSPHERE We all know that water occupies 75% of the Earth’s surface. Water is a component of living cells and every cell in a living organism is made up of almost 75% water and this let the cell to function normally. Life would not exist without water. Water gives habitat meaning the hydrosphere gives a significant place for many animals and plants to exist. Water takes a long time to heat up and it also takes a long time to cool down. This is important in helping to control temperatures

Water is a human right‚ not a commodity. It is the essence of life‚ sustaining every living being on the planet. Without it we would have no plants‚ no animals‚ no people. However‚ while water consumption doubles every twenty years our water sources are being depleted‚ polluted and exploited by multinational corporations. Water privatization has been promoted by corporations and international lending institutions as the solution to the global water crises but the only one’s who benefit from water

Necessary minerals are from time to time divided up into major minerals (macrominerals) and trace minerals (microminerals). These two groups of minerals are equably valuable; however trace minerals are needed in smaller amounts than major minerals. A well-adjusted diet frequently provides all of the
