Environment, water, air etc;, are natural resources. Energy is produced by a man but is also a natural resource, I call it, like other resources. Like is cooking gas also. There is no reason to waste these resources. A rich man may be having lot of money. But he has no right to waste these resources. While we walk on a road, if we see a Rs.10/- note, we will take it. Same is the case with material also. Nobody is having right to waste it. Make them the best use. But never waste them. This should be the concept. You waste the money if you have excess but not natural resources. This should be the concept.
I read some where. Mr. Ratan tata and some of his friends went to a restaurant in France and ordered for lot of food. Half of the food was left out and got wasted. One old man of that country came near these people and asked them why they have wasted that much food. One of them replied that they have paid for it. The old man said you may be able to pay money but you don't behave right to waste our resources. Mr.Tata him self mentioned this.
