The Three R’s to save the environment

– The three R’s to save the environment are Reduse, 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.

SUSTAINABLE DEVELOPMENT: economic development that is conducted without depletion of natural resources.

Why Do We Need To Manage Our Resources ?

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


Forests are ‘Biodiversity hotspots’. Hotspot means an area full of biological diversity.

The biodevrsity of an area can be measured by determining the number of species found there. The main aim of conservation is to try and preserve the biodiversity.

Conservation of biodiversity is important to maintain ecological stability.
