Conservation of Natural Resources
Humans have always made use of other species. Most wild species are found in areas where people live. This is either because people want to gather natural resources from there or they put their life to risk for purpose. Over the last 10, 000 years our food has come increasingly from cultivated plants and animals. This has resulted in the rapid increase in human population. The wise and smart use of the earth's resources by humanity is termed as conservation of natural resources. The term conservation came into use in the late 19th century. Conservation includes both the protection and rational use of natural resources. It was related to the management (the act of caring something) of very special natural resources like timber (tree used for building purposes), fish, game, topsoil (upper layer of soil), grass lands, forests, wildlife and useful minerals. In recent years the science of ecology has cleared the workings of the biosphere; i.e., the complex interrelationships among humans, other animals, plants, and the physical environment. At the same time increasing population and pollution along with increasing industrialization have proved how easily our balanced environments can be disrupted. Thus conservation of resources can also be defined as “Protection and Sustainable use of resources”.
Types of Natural Resources:
There are two types of natural resources; renewable or non renewable. Renewable Natural Resources:
These are the resources which are never depleted and natural cycles constantly replace these minerals. Air, water, forests, soil etc are example of such resources. Non-Renewable Natural Resources:
The resources that are depleted or destroyed and cannot be reused. For example mineral, oil, gas, coal and fossil fuels. How Natural Resources are getting depleted?
The combination of growing populations and increasing levels of resource consumption is degrading and depleting the natural resource base. The world's population stood at 850 million at the onset of the industrial age. The global population has grown to nearly seven times as large (6 billion), and the level of consumption of resources is far greater. This human pressure now exceeds the carrying capacity of many natural resources. This is how the natural resources are getting depleted.
Steps that can be taken in future to conserve resources:
Whenever we save energy, we not only save money, we also reduce the demand for such fossil fuels as coal, oil, and natural gas. Less burning of fossil fuels also means lower emissions of carbon dioxide, the primary contributor to global warming, and other pollutants. We do not have to do without to achieve these savings. There is now an energy efficient alternative for almost every kind of appliance or light fixture. That means that consumers have a real choice and the power to change their energy use on a revolutionary scale. The average Pakistani produces about 40,000 pounds of CO2 emissions per year. Together, we use nearly a million rupees worth of energy every minute, night and day, every day of the year. By exercising even a few of the following steps, you can cut your annual emissions by thousands of rupees and your energy bills by a significant amount! Home appliances:
1. Turn your refrigerator down. Refrigerators account for about 20% of Household electricity use. Use a thermometer to set your refrigerator temperature as close to 37 degrees and your freezer as close to 3 degrees as possible. Make sure that its energy saver switch is turned on. Also, check the gaskets around your refrigerator/freezer doors to make sure they are clean and sealed tightly. 2. Make sure your dishwasher is full when you run it and use the energy saving setting, if available, to allow the dishes to air dry. You can also turn off the drying cycle manually. Not using heat in the drying cycle can save 20 percent of your dishwasher's total electricity use. 3....
