Ans.Conservation of Nature
Conservation of nature means the conservation of natural resources. Everything that we use or consume e.g. food, petrol etc. is obtained from natural resources. The renewable natural resources e.g. air are reproduced easily but the non-renewable resources (e.g. minerals and fossil fuels) are not replenished once they get depleted. We have to conserve the non-renewable resources because their reserves are limited and humans are heavily dependent on them for daily needs. The renewable resources too have to be judiciously used. To ensure sustainable use of resources in our environment, we should act upon the principle of The 3R'i.e., Reduce, Reuse and Recycle.
The R1: Reduce: We should use the natural resources less and should not waste them. We should use this principle at different places, in our daily lives. We should not waste water, electricity, fuel etc. We should turn off the tap when not in use. We should bathe with a bucket instead of shower. The lights and fans should be off, when we are not in room. We should take public transport (like buses) or walk short distances instead of using motor fuel. We should not waste food and should give unused food to poor people.
The R2: Reuse: We should Use a thing again and again. We should not throw away materials such as glass containers, plastic bags, paper, cloth etc These should be reused at domestic levels rather than being thrown. It also reduces solid waste pollution.
The R3: Recycle: Materials such as paper, plastic, glass etc. can be recycled. This decreases the volume of refuse and helps in the conservations of natural resources. For example, a recycling of one tone of paper can save 17 trees.
(We can add the R4 i.e. Reforest. Trees should be planted during the rainy season.Trees make our environment more cool, shady and green).
