Why is a city's ecological footprint bigger than the actual land taken up by the city?

Question

i did some research online and it says "because of production of food, commodities, disposal of wastes, etc" but what does that mean. how can an entire city reduce its ecological footprint but more importantly how do you convince people to take care of the environment?

Answer 1

well for starters.. you can't have a big farm to feed a city, right in the downtown of a city.

reduce footprint by using less stuff, energy..etc.

Convince people... not an option... can't fight the corporate media's control.   We need 'radicals' to stir things up.

Answer 2

you can't stop or reduce the foot step, it's human nature where we want EVERYTHING

those people who has power will want to hold everything in their hands and this includes power, money, land...etc

there is NO WAY to stop they from satisfying their desires and greed

they want their city to look like a concrete jungle so they don't want the farms to be in the city, this causes the expand of the territory

people wouldn't want to go travel to food/animal farms so they will travel to somewhere where it's not been developed yet
