Ecological Footsteps

Here’s a small biology lesson that tied in with helping to reduce air pollution. While reading my biology textbook, I came across a peculiar term – ecological footsteps. Now what in the name is that and how does it involve us?

Ecological footstep is a measure of human demand on the Earth’s ecosystems. It represents the amount of biological productive land and sea area needed to supply resources for humans to consume. This includes areas that food is produced, land for buildings and roads and ecosystems for absorbing its waste emissions such as carbon dioxide.

Wait, did I read that right? Carbon dioxide? Yep! Carbon dioxide. Since the 1970s, humanity has been in ecological overshoot with annual demand on resources exceeding what Earth can regenerate each year. Overshoot is a vastly underestimated threat to human well-being and the health of the planet, and it not very adequately addressed.

We have to take care of what we exploit from the lands – because our ecological footsteps are on overdrive. So cut down on your consumption for needing energy and other resources – let’s make a a goal to slowly reduced our ecological footsteps!
