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.

Biggest Impact Humans Have Had on the Planet
After watching Earth After People, I think that without humans, the earth would go back to the way it was before when there was no buildings or signs of civilizations. Animals would run free and live by the idea of survival of the fittest. The world would be darker because there would be no electricity or light. I think the biggest impact that humans have on the planet is our ability to control areas and build things on top of it. We don't let things such as plants or trees take over the planet but instead we make things organized. We also have negative impacts on the planet such as pollution and overusing the earth's resources.

Individual characters/Population sizes
Individual characters of animals affect their population sizes. This can be seen in the studies of Darwin during his stay at the galapagos islands. He studied finches in all the islands and he saw that the finches had different characteristics because they had to adapt to the environment around them. So for certain islands, only a certain kind of finch with features and characteristics that fit the surroundings would be found in a large population while other finches would have low or no populations in those areas.


Four Types of Competition
There are four types of competition in the environment that exist within the animal kingdom. These types of competition determine which animals are superior and get to thrive within a certain area in a specific area. Intraspecific competition is the competition for resources between two of the same species. An example of this is two guys fighting for one girl or two of the same birds fight for one nest. Interspecific competition is the competition for resources between two different species. An example of this type of competition is a cat and dog fighting over a bowl of food.
