Sustainable environment online is a website that makes you think outside of the box. The Earth is unique in the solar system in that, as far as we know, it is the only place that sustainability and the environment make life possible on our planet. Some people even like to view the Earth, or Gaia after the Greek Earth goddess, almost as a living thing itself. Environment resources and sustainable development on Earth has passed through many stages of dynamic evolution. Human beings represent just the latest snapshot in evolutionary time. Humans, however, through pollution and overconsumption, may now be beginning to threaten the sustainability and the environment of Earth's life support systems. How we chose to respond will depend on how we view our relationship with the environment.
