Sustainable Development means using the resources carefully to meet the needs of the present, without compromising the ability of the future generations to meet their own needs. It's all about the balance of utilisation. 

Imagine having a chocolate bar, would you eat the whole thing today or save some for tomorrow? Sustainable development is about leaving "enough chocolate" for everyone.

THE THREE PILLARS OF SUSTAINABILITY
