Ecological Footprint

It would take 4.2 Earths and 18.5 global acres to provide resources to support my life style. I see a footprint in two different ways. One way is like leaving a mark somewhere on the Earth. Also making some kind of impact to or on Earth. Those are the two ways I see a footprint. If everyone on this planet would reduce their ecological footprint, then our Earth will "live" for longer than we expect it to. One way I could reduce my ecological footprint would be to eat lest processed food and buy more of my food from local food markets. Also, maybe I could make a road trip to go see my family instead of flying there. It would probably be better for me since I'm terrified of traveling on planes.
