Sustainability is....

• Recognizing that you form part of a system, and that your actions have an impact on whether or not you can carry on with that way of life.
• Using only what you need.
• Using resources responsibly.
  
• Respecting nature, not abusing it.
• Meeting your needs without harming nature.
• Living in such a way that you ensure that life will carry on and that quality of life will be maintained.
• Being able to maintain your living conditions because of the fact that the environment is not being abused, and thus can keep providing the necessary resources.
• Making sure that future generations will have a world to live in and care for.
  
• Teaching future generations what it means to form part of an ecosystem.

This and many more things define sustainability. Sustainability is not a simple concept that can be defined in two or three sentences. It is a way of life. It is something that should be applied in all aspects of life. It should be a way of measuring our actions.
