 //__** What is overpopulation? **__//

Overpopulation is when there is many organism's in their ecosystem that their population is too high for the amount of resources to support. That is called its carrying capacity. For example, if too many animals of one species, such as rabbits die, there is no more of that animal for its predator, a fox. The fox population needs the rabbits for food so it can be supported to live. If too many organisms do not have a mate, they can't have offspring so that animal's population will decrease.(2) In a food chain when there is too many of there prey, then the predator can consume more food. Because of that surplus they can repopulate more so there population increases rapidly. Becasue those new predators need food and there is not enought of the prey to support them all, the predator's population will decrease. Since the predator population goes down, the prey is able to repopulate and be able to return to its natural population. The predator's population will return to its natural population over time and the process will start over again. A fact about overpopulation is the speed of natural human growth is growing more then 10,000 times faster then normally human growth!(3)

**//__ What causes overpopulation? __//**

Overpopulation is caused by changes in limiting factors. One major factor that affects the population is when the food suply increases. When there is more food for that specific speicies, it is able to support more of those organisms to live and to reproduce. That makes the birth rate increase which is another limited factor. The death rate also plays a role in overpopulation. If the death rate decreases dramatically, it causes an increase in population.(1) Immigration also has an effect in the population. When too many new organisms migrate into the population, it becomes overpopulated. (4)

** //__How can__// //__Effects of Overpopulation be helped?__// **

Overpopulation and be helped by slowing the birth rate. and some of the organisms emmigrating to a new area.(1) You can slow the birth rate by not reproducing until the population returns to its natural capacity. Some animals like dogs and cats can get spayed or neutered.(2) Also make sure the pets can be socialized so they don't have bad behaviors, you can adopt more pets and have them trained.

__ // ** Does Overpopulation only effect the enviorment? ** // __  Population does not only affect enviorment but it does also hurt humans. Overpopulation of the world can lead to poverty, As more and more people are on this planet, the resources will run out. There will not have enough for plant life, so the animal life will disappear. We can't live without other plant life or animal life so humans would die too. By keeping the population at a mantained level, it can help keep the pollution levels,disease, and resource levels at a reasonable level as well. (3)

 
 * __ // What are Some Effects of Overpopulation? // __**
 * Low life expectancy.
 * Countrys that have fast growing population.
 * Starvation- there is competition for food.
 * Scarce resources such as food, water, etc,,
 * Loss of ecosystems.
 * <span style="font-family: Arial, Helvetica, sans-serif;">Overuse of natural resources, this causes air pollution, water pollution, soil comintation and sound pollution.
 * <span style="font-family: Arial, Helvetica, sans-serif;">Changes in atmospheric composition.
 * <span style="font-family: Arial, Helvetica, sans-serif;">Global Warming.
 * <span style="font-family: Arial, Helvetica, sans-serif;">Many extinctions of plants and animals as habitat is used for farming and human settlements.
 * <span style="font-family: Arial, Helvetica, sans-serif;">Depletion of energy resources as the demand for energy increases.

**__ Connection of gray area? __**<span style="font-size: 90%; font-family: Arial, Helvetica, sans-serif;">This has to do with gray area because in our notebook we talked about how they took away hunting in parallel park. Because that limiting factor was taken away, many animals overpopulated the land. For example, If a deer population had 20 deer on average then the hunting is taken away, the population goes up to about 50 deer on the land. Also some more deer could immigrate on to that land so it becomes even more overpopulated and these deers wouldnt be able to have food or any resources. That causes competition because they are fighting for their food or any other resource's.(5)
