The project educates on sustainability, meaning, content that refers directly or indirectly to a current definition of sustainability.

• Sustainability is based on a simple principle: Everything that we need for our survival and well-being depends, either directly or indirectly, on our natural environment. Sustainability creates and maintains the conditions under which humans and nature can exist in productive harmony, that permit fulfilling the social, [cultural, environmental], and economic requirements of present and future generations.
• Sustainability is important to making sure that we have and will continue to have, the water, materials, and resources to protect human health and our environment.
