That is about a third of the population today. Imagine all that waste. Now, try and decide where to put it. There is nothing that we can do to minimize population but there are ways to minimize the amount of waste people accumulate, like the three R's. There are two ways that trash is disposed of, incineration and landfills, burning or burying.
Incineration consists of burning waste to produce energy.
Land fills consists of burying waste in a giant hole. The following are descriptions of how these two systems work. Your home, child's school, or even community park could be built on an old landfill. A landfill is a big hole in the ground. The hole is dug out deep enough for garbage trucks to be able to drive into them.
