The Three R’s to save the environment
The three R’s to save the environment are Reduce, Recycle and Reuse.
- Reduce: means using less of natural resources and avoiding wastage of natural resources.
- Recycle: means the materials like paper, plastic, glass, metals etc. used for making things can again be used for making new things instead of synthesizing or extracting new paper, plastic, glass or metals.
- Reuse: means using things again and again like the plastic bottles in which we buy jams, pickles etc. can be again used for storing things in the kitchen.
We must be careful about the effect our choices of living make on the environment. Economic development is linked to environmental development. Thus, sustainable development is important.
Economic development that is conducted without depletion of natural resources.
Sustainable development is way to use resources in such a way that our need fulfilled without compromising needs for future generation.

- they are limited in quantity.
- Due to increasing population, their demand has increased resulting in overuse of resources.
- These resources take a really long time to form thus depletion will cause problems for the future generations.
