Dam Descusion

The topic of dam use in our environment is a controversial topic on many levels. The list of pros and cons is a long one and the positives and negatives never seem to be all on one side. There are good points and bad points weither you look at it from a environmental, economic, or scientific point of view.
After reading all the research done on dams, we might ask ourselves, "Should dams be taken out of rivers?"
I feel that dams are essential for providing the astronomical amount of power needed to sustain the world's population and energy needs. Dams provide cheap power, increase available water supply to residential areas, and beautify areas surrounding these dams.
Firstly, power provided by dams is cheap in comparison to other sources of energy. It has the ability to decrease green house gases and the money saved from producing dam energy can be used to fight global warming, make homes energy efficient and re-plant forests.
Secondly, dams provide water to areas that would normally have periods of drought and have failed crops due to poor irrigation. Farms have the opportunity to prosper, wildlife and fish flourish and drinking water is plentiful. Water is less likely to become contaminated in areas that have abundant water supply from dams.
Thirdly, dams beautify areas surrounding them. There is lush vegetation, healthy trees, plenty of birds and wildlife. Dams also provide parks, skating ponds, walking trails, fishing spots, and boating.
Therefore, I feel that dams should remain in the rivers and that they are essential for providing the amount of power needed to sustain the world's population and energy needs.

Aerial Wolf Hunting

Did you ever wonder what would happen to the food chain if the number of wolves continued to grow and the overpopulation of wolves continued ? This is a question that is raised when considering aerial hunting as a viable option to control the wolf population. Right now, there is an overpopulation of wolves and i believe aerial hunting is a good way to natural order in the food chain. I also believe that there should be a cap on the number of wolves that each hunter can shoot and I believe that aerial hunting should only be allowed for 2 years, then a new study performed.
Environmentally speaking, on the plus side aerial hunting would decrease the loss of game animals and farm animals that are killed by wolves every year and in the long term allow for increased number of game animals for avid hunters and more lead to prosperous farms. On the negative side, there would be less wolves to feed on the rodents and if aerial hunting was not capped or re-studied in 2 years the result could be disease and infestation of rodents.
Scientifically speaking, on the plus side there would be less wolves in the food chain if aerial hunting was allowed therefore the animals that are being eaten by the wolves would be able to reproduce and their populations would be restored. Negatively, sick and unhealthy animals that are being preyed on by wolves would not be killed off and rabies could become epidemic.
Recreationally speaking, on the plus side of aerial hunting is that there are currently lots of wolves to hunt therefore it is fun sport and it is one that is safe for the hunter. The hunter is not in direct contact with the wolf so there is no chance of a human fatality and in the long term there would be increased the numbers of caribou and moose to hunt in the future. Negatively, the wolves would become over hunted if there was no cap and wolves could become an extinct species.
So I feel that aerial hunting of wolves is a safe way to lower the over populated wolf species but i think that there should be a cap on the number of wolves killed by each hunter and the numbers should be re-examined in 2 years.
