Resource conservation is a necessity since the quantity of resources is limited. There are a number of examples from our daily life where we can conserve resources. Recycling is one way we can conserve resources. The soft drink plastic bottles can be recycled in a number of ways. They can be used for keeping water in a refrigerator. They can also be used for constructio, in place of bricks, by filling them with sand. They can also be as flower pots by cutting them in half. Another example is use of reusable bags for groceries and shopping, instead of plastic bags. Another example is the use of handkerchief instead of paper napkins. We can also store and use rainwater by rainwater harvesting. Another example is carpooling to save fuels. You could also turn the heat down by a couple of degrees at home and save on electricity (which is typically generated by fossil fuels).
Hope this helps.
