So this question is, actually, if your question is in one, it's based on humans and ecological footprints.
00:08
So the first one is asking, how are humans in ecological footprints connected? why the different ecological differences are in the world, and how can reduce the human footprint to sustainable level, the human ecological footprint? so to answer the first one, the ecological footprint is land, base, and humans use land.
00:31
We need land for our buildings.
00:34
We need land for our roads.
00:36
We need lands for food.
00:38
So basically we're using land all the time.
00:41
Even if we're not in for just sitting in our house, if we go to eat an orange, you're using the land that that orange was grown on.
00:52
Second one is, why are there different ecological footprints around the world? and it's because there are different levels of income.
01:04
Around the world and so wealthy countries you have a bigger ecological impact people use more of the land overall i mean just think about all the different food types you might go to the grocery store and see think about all the urbanization all the roads things of that nature so wealthy countries use more in land they use more energy, which that goes back into things like mining or wind turbines.

And then the third question is, how can we reduce the human footprint to sustainable level? this is a hard question, and there really isn't one correct answer...
