conservation of natural resources
Introduction conservation of natural resources, the wise use of the earth’s resources by humanity. The term conservation came into use in the late 19th cent. and referred to the management, mainly for economic reasons, of such valuable natural resources as timber, fish, game, topsoil, pastureland, and minerals, and also to the preservation of forests (see forestry), wildlife (see wildlife refuge), parkland, wilderness, and watershed areas. In recent years the science of ecology has clarified the workings of the biosphere; i.
e., the complex interrelationships among humans, other animals, plants, and the physical environment.
At the same time burgeoning population and industry and the ensuing pollution have demonstrated how easily delicately balanced ecological relationships can be disrupted (see air pollution; water pollution; solid waste). Conservation of natural resources is now usually embraced in the broader conception of conserving the earth itself by protecting its capacity for self-renewal. Particularly complex are the problems of nonrenewable resources such as oil and coal (see energy, sources of) and other minerals in great demand.
Current thinking also favors the protection of entire ecological regions by the creation of “biosphere reserves.” Examples of such conservation areas include the Great Barrier Reef off Australia and Adirondack State Park in the United States. The importance of reconciling human use and conservation beyond the boundaries of parks has become another important issue.

We can live without food for three to five days a week, but we cannot stand for living without water for a day.
Water is the basis of lives living on earth. But without a proper condition of water, there must be a bad effect on all types of lives as well. As it becoming worse because of the pollution and the climate change, water conservation is the perfect way to improve the quality of water as well as to balance the current and future water needs.
To get through the water conservation, we should know the important, the goal and how we can conserve the water. If you have any questions, I’ll be very happy to answer them at the end of my presentation. Ok, to begin with, let’s have a look on what the important of water conservation. To human, water provides us a huge need for the basic needs as we need fresh water for drinking, to cook thing and to use in things we cook; for example, in the soup, cake, dessert, porridge and so on and we also need freshwater to wash ourselves for being clean and hygiene, to wash clothes for being fresh, to wash dishes for getting away from any kinds of gems, and even to wash our vehicles as needed. Freshwater is used in many ways. We can also use freshwater to improve the sanitation, irrigation, industry and so on.
To animal, freshwater plays a very important role as their fundamental needs including the home for species and for drinking. Not different from the human kind, animal need water to support their buddies to survive. For water species, water is not only a basic home but also a place for them to get food. To the environment, freshwater can create the green which can also help both human and animal living in a good condition, for they will live in a kind of environment without pollution. Also, by growing greenery everywhere, it is a great function to cause the rainfall from the forest. And that really benefit to the living situation. That’s all I have time for the important for water conservation.
