Even though certain pesticides, such as DDT, DDD, DDE, are no longer being utilized in the Chesapeake Bay area [largest estuary in the U.S.], scientists have seen its remnants lingering around the Bay's airshed. Many of the pesticides lingered within the soil, and since much of the coast is sandy it is likely to give off the pesticides more. This means that the pesticides will continue to be released within the area due to their persistent nature. Other pesticides found were lindane, chlordane products, heptachlor, and dieldrin [this is the most persistent and along with DDE, had the highest concentration found]. Some of these pesticides were even found from being as far away as 60 miles. About 30-60% of the pesticides were caused to arise from air temperature and wind. These findings will hopefully provide a sense of awareness to users of pesticides so that they know that the damage of pesticides aren't just during the time it is sprayed, or even as long as making its way to the dinner table. They can remain for decades and harm current organisms in the area, including us humans.

Human Population Growth and Poverty
http://www.globalissues.org/article/200/population-and-feeding-the-world
Nowadays, hunger is seen as one of the world's most prevalent issues. There have been millions of lives lost due to being malnourished, but its main problem isn't just not living in agricultural areas. Currently it is estimated that 925 million people in the world are hungry, nearly 1/7 of our world's population. Also nearly 80% of the world's population lives on under $10 a day and nearly a half of the population lives on less that $2.50. People don't just go hungry because they simply don't live in an area where food is produced, but because the food cannot be purchased. For many people, the daily cost of food is far too much, even though there really is enough food for all to eat, it's mainly that there is too much poverty. Due to this poverty many cases of death arise and even some people, such as Somalian warlords, take advantages of this terrible status and use it for their own power and gain. If we are to save people that are living under terrible conditions such as these, we must send out a reaching hand, but also get rid of corrupt individuals.

7 Billion Inhabitants and Resource Struggles
http://www.msnbc.msn.com/id/45106316#.TrIMj_QUq30
As many are aware, this past Monday introduced to the world the 7 billionth inhabitant. The human population has constantly been growing at an exponential rate, and a high one at that. Some scientists would debate that we've already passed our carrying capacity, or are closely nearing it, but when looking at statistics it appears that people are already losing resources in extremely large areas of the world. As our population increases more and more, we lose even more resources, and more people will be without them. The struggles that we as people face are so enormous, since we just take what suits us and helps us out at the moment, not knowing its impacts on the future. We have been destroying the world, and more of us continue to enter the world, and at an incredibly fast rate. Will we begin to have a die off of individuals within our lifetime our any near generations, or will we fix our problems before such a thing occurs, but only time will tell.
