The three R’s that need to be practiced in order to save the environment are:
Reduce: Reducing the usage of resources will help save them for the future. E.g.: reducing usage of electricity by switching off fans and lights when not in use.
Recycle: Plastics, paper, and glass can be recycled to make other objects.
Reuse: Using things again and again. For example, jam bottles made of glass can be used to store salt, sugar, oil, etc.
