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.

Soil Preservation

Soil Preservation from erosion is more important than saving endangered species or finding other energy sources. The reason behind this is that crops grow on soil and if the soil we grow food on gets eroded or ruined, then it will be harder to plant crops and harvest food. This is a significant part of humans' lives. Agriculture is the most important part of society because it is the part that feeds all people. If there is no agriculture, humankind may not last.

The Green Revolution

In my opinion, the Green Revolution is good because it has developed more varieties of wheat. It is an agricultural research station. It allowed food production to keep up with world wide population growth. The Green Revolution has started many programs that helps countries such as Mexico do this.

Food Safety Policy/Law for the U.S.

In the United States, we do not uphold any regulations or laws that force genetically enhanced foods to be tested before the products are put onto the shelves of supermarkets. Consumers are not informed that some of the foods that they are purchasing and eating are actually genetically enhanced. This poses many problems because the genetically enhanced products may cause allergic reactions or cause death to people and the public will not know the cause. We, as consumers are blindly buying into the genetically modified products and they are not even labeled or tested.
My policy for safety in genetically modified objects would be that all genetically modified foods and items must be tested for any side effects and each product that is approved to be put into sale must have labels that indicate that they are genetically modified. The incentives are that people will be safer and GMO's that follow this law will be able to be sold. The sanctions will be if any company disobeys this policy they will receive lawful punishment and fines.
This policy will increase public safety when it comes to food because now people will know what they are purchasing, whether it is natural and organic or genetically modified. We might also figure out if these GMO's cause any illnesses, diseases, allergic reactions, or even death.

Preventing Food Diseases

In order to prevent obtaining illnesses and diseases from food such as food poisoning, we can take many steps to keep ourselves healthy and safe. One good way of preventing food diseases is to have separate cutting boards for vegetables and meats. That is because raw meat can have bacteria that can be passed on to vegetables if we cut them on the same board. Also we should cook all meat until there is no more blood to ensure safety. Always wash your hands under warm water for about twenty seconds before handling any foods.

3 Factors That Lower Biotic Potential

There are many factors that lower biotic potential but there are three that are the most significant factors in my opinion. Biotic potential is the maximum reproductive capacity of a population under optimum environmental conditions. Environmental resistance restricts full expression of biotic potential. The three factors that do this are famine, natural disasters, and weather.
