Frequently Asked Question

Question 1: How can we protect our environment according to Chapter 15 of Class 10 Science?

Ans: As we already know that we disturb and destroy our environment by adding waste to it. Human beings share our environment with thousands of other living and non-living organisms. To protect our environment, we should reduce the amount of waste that we produce. We should reduce the usage of products that have a short shelf life and produce waste after their disposal such as plastics. Recycle various products such as paper and use them again. We can limit the usage of products that emit CFCs into the environment.

Question 2. What is the environment as mentioned in Chapter 13 of Class 10 Science?

Ans: The environment is a very big term as it includes human beings, plants, animals, books around us, the soil and everything else around us. Our environment provides us with the land on which we live, the air we breathe, the food we eat and the clothes we wear. It contains many essential nutrients such as oxygen, carbon dioxide and nitrogen.
