Recycling and ecological economy

Reducing natural resources consumption, energy use, emissions and waste is beneficial for the environment. However, it's urgent to promote eco-effectivity: working to make products, services and systems environmentaly correct, instead of changing incorrect things into "less bad" things.

Food preparation with solar energy is one of the main tools of Terra Foundation to show renewable energies to the public. The long experience in this field and the organization of several related events like the Encuentro Solar (Solar Meeting) allowed for knowing many of the people involved in the design of solar ovens and cookers.
