4R means Reduce, Reuse, Recycle and Restore

 

• Reduce- We must reduce the use of resources as much as possible and save them for the future generation. Reducing the usage is a method of conservation of resources.
• Reuse- Resources can be reused wherever possible. We need not produce resources on large scale which may lead to exploitation of natural resources. Instead we can reuse them.
• Recycle- Resources can be recycled wherever possible so that they can be used again and again.
• Restore- We can restore resources into their original state, wherever possible.
