Immagration and pollution
The Effects of Population Growths on the Environment With world population skyrocketing, where is man-kind headed? The current world population is over six billion with the United States population alone numbering over 264 million. Studies on population growths project that by the year 2050 A.D., the U.S. will need to find room for more than 520 million people, almost doubling the current population. How will the environment and the human race itself be affected by this (Jackson 27)? First, we as inhabitants, need to know what we are doing to this place we call home, Earth. The consequences to the United States wild lands and all their resources would be overwhelming if the population saw those kinds of staggering numbers. A striking illustration is the national park system: since 1940, the U.S. population has doubled, but park visitation has increased sixteen times. A population increase that measured only half as great as the last fifty years would devastate these areas, diminishing the quality of visitors' experience and reducing resources to unsustainable levels (Jackson 30). Recently it was found that MTBE (a gasoline additive that makes engines cleaner-burning, but may also cause cancer in humans) could be leaki
I'm not for the U.S. or any other country to put limits on the number of children families are allowed to have, or any sort of restrictions that are associated with that. What I am saying is that everyone needs to be aware of where the world is headed. If we as human beings keep on living the way we do, there won't be a suitable place to live on Earth. The way this race destroys its home is amazing. A common saying is one person can't make a difference, and in this case that's right. What if though, everyone started thinking that one person could make a difference, then six billion plus people started making a change for the better. Now is that realistic, no, but if a third of those of the population thought that way, just imagine the possibilities. Precipitation normally has a pH level between 5.0 to 5.6 because of natural atmospheric reactions involving carbon dioxide. Precipitation is considered to be acidic when its pH falls below 5.6, which is 25 times more acidic than pure water. Some sites in eastern North America have precipitation with pHs as low as 2.3 or about 1000 times more acidic than natural water (Carousel 34-35). Acid deposition influences the environment in several different ways. In aquatic systems, acid deposition can effect these ecosystems by lowering pH levels. One of the most obvious effects of aquatic acidification is the decline in fish numbers. Originally it was believed that the fish died because of the increasing acidity of the water, but it was later discovered that high acidified lakes also contained high concentrations of toxic heavy metals like mercury, aluminum, and cadmium. The source of these heavy metals was the soil and bedrock surrounding the water body. These toxic metals are easily leached by infiltrating water into aquatic systems where they accumulate to toxic levels (Carousel 35-36). Developed nations must work towards greater conservation of resources in order to reduce the impact on depletion of non-renewable resources, creation of pollution, and damage to ecosystems by providing more equitable opportunities for people throughout the world. The United States must help influence the world in this direction. The U.S. foreign assistance program and other U.S. international activities can be major means to address such concerns. This is essential to improve environmental protection, and to further environmentally sound development in all countries of the world (Jackson 35). When a society has more people relying on their environment than they can properly sustain, they are not able to produce enough food required by the excess residents. This need for a bigger fo
