Our current impact on Planet Earth

One way of looking at the devastating effect our civilisation is having on Earth is to look at it in terms of what would happen if we did suddenly disappear from this place.

This timeline gives a visual view of how long it takes for nature to regenerate. Within 3 months the air would be mostly clean again. Within 250 years most buildings collapse. Within 1000 years most buildings are gone.

However, it takes 50,000 years for plastics to degrade, many man-made chemicals will disappear only after about 200,000 years, and nuclear waste will grace our planet for up to two million years. Quite a legacy!

Well, here is the challenge: develop and live a sustainable life-style that doesn't bequest a toxic legacy for the next two million years into the future! One that allows us and our decendants to live here indefinitely!
