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.

importance of eating lower on the food chain

It is very important to eat lower levels of the food chain such as producers. Some examples of producers that are good to eat are plants and vegetables. We should also eat fruits such as apples and bananas. It is not only good for the environment, but it is also good for our personal health because most producers are healthy to eat. Beans and tofu is also good to eat.

why some animals/plants are stronger but weaker animals/plants thrive

Some large and strong animals such as a wooly mammoth or a dinosaur have become extinct in today's world but other animals such as cockroaches and plants such as fungi and lived to survive the millions of years of natural disasters. In my opinion the reason to this baffling question is that bigger animals are more prone to get wounded during natural disasters such as the ice age in the case of the dinosaurs but smaller plants and animals can be missed by these things. Cockroaches are also a fascinating type of animal that can withstand a nuclear bomb so that is also a big factor.

most important person in environmental science

I think out of all the people mentioned in chapter 3, the most important person to the cause of environmental science would have to be Audobon because although he only started the bird rescue movement, it also lead to the formation of the audobon society which does more than save birds in the environment. They do alot of work for the environment and even more all due to him.

endangered animals

An endangered species I think that we should save is the giant panda bear. The population of these animals are at its lowest and we should help save them from hunters and poachers. Pandas are rarely found in the wild but most are located in areas in China. Here is a rescue site link for various animals including the giant panda: http://www.webring.com/hub?ring=animalrescue
