Ecological footprint


 It  is a way to measure the area of the earth required to supply  all the resources we use to support our lifestyle.  It can asses the sustainability of current human activities and  a  concrete indicator that shows  our impact on the planet.  The choices we make in our homes, our travel, the food we eat, what we buy and throw away,  all influences  our ecological footprint. Through measuring our  ecological footprints  we can see our influences on our unique planet. Let's measure our ecological footprints and think some solutions to reduce our individual harm.
