3 soil problems & solutions

There are many soil problems. One of the problems with soil is that we are running out of good fertile soil to plant things in. Many people try to plant seeds in rainforest soil which ruins the soil. It ends up with the land being dead and the plants not growing. A solution to that problem is that people should stop planting in rain forests because it is bad. Another problem is that more and more things are being built on unsettled land and we don't have enough room to farm. As lands are being taken over, bought, and dug up, we have less and less soil to plant things on. The last problem is that a lot of trash are being buried in soil and not all of the trash can be biodegradable. Such things as plastic and styrofoam cups may take years to biodegrade. We should not dump trash in landfills but instead recycle.

Human Footprint DVD

Three things that I learned from the Human Footprint DVD is that humans are accumulating too much trash, we don not recycle enough, and that we need to conserve. The DVD showed astonishing numbers of how many diapers we use, how much milk we drink and the costs of having cow farms. We use too much plastic which we do not recycle and goes into landfills. A lot of our trash just goes into dumps. They only showed our human footprint for certain things such as diapers, bread, etc. but humans use lots of nonrenewable resources and we need to stop before things get worse.
