A’Nyiah Brown 10/30/2012 Professor Joseph DDT vs The Human Race Should DDT be reapproved for the use in the wake of recent bedbugs across the country? Through the research I have found, I see that DDT should resurface because it hasn’t been proven that this chemical isn’t harmful to the human race or animals. DDT has been known to control pesticides in crop, livestock production, bedbugs infestation, and help end the spread of the Malaria. If this synthetic chemical is actually helping others then it should resurface. DDT also known as dichloro-diphenly-trichloroethane is an organochlorine insecticide which is a white, crystalline solid, tasteless, almost odorless and was discovered in 1939 by Paul Hermann Muller.
Little Bee, Big Impact Laura Matthews Rogue Community College ABSTRACT This essay presents the global issue of the massive decline of the population of honey bees. The significance of this essay is to raise awareness of this potentially detrimental environmental concern. Sources including the United States Department of Agriculture and the Environmental Protection Agency show that even though no cause has yet been determined it is vital that a solution be found. Honey bees have been referred to as biological indicators, meaning that their status is a reflection of the general environmental health of the planet as a whole. Little bee, big impact Imagine a world without fresh fruits, veggies, and nuts; strawberry shortcake wouldn’t exist and a slice of juicy watermelon on a hot summer day would be only a memory.
Dr. Vagelos would make the final decision. Analysis Although Dr. Campbell’s idea of a drug that could cure River blindness was a great opportunity for Merck, the company was faced with a number of ethical, financial and moral issues that forced its CEO to contemplate before investing in this idea. First, the odds of developing a successful drug are rather low and entail high investments. On an average it took 12 years and $200 million to bring a new drug to market. Also, there were worries about ivermectin might do harm to patients’ health because it had some negative side effects on mammals.
The European honeybee plays a key role in pollination. About one third of the world’s food crops along with the reproduction of plants depend on honeybees for pollination. Honeybee deaths are on the rise across the world and the main cause of the honeybee death comes from pests and pathogens such as mites, viruses, bacteria, fungi and other insects. Beekeepers are also pointing their fingers at Monsanto, the leading producer of genetically engineered seeds and food, for the honeybee collapse. Monsanto’s solution to the colony collapse is to genetically modify bees and make them resistant to all the pesticide producing food they make.
According to the Hawaii Department of Agriculture is participating in a multi agency campaign to stop the spread of the coquis in Hawaii. The reason for this is because the coqui doesn’t have a natural enemy to keep the population down, also because of the warm temperature they breathe year around. The Hawaii Agriculture department stated that “in some area’s the population of the coqui is around 10,000 frogs per acre” no wonder people in Hawaii can’t sleep It is like a law mower running all night. If someone in Hawaii is caught transporting or selling a coqui is in violation of the Hawaii state law. Which is a class c felony and they will be fined of $50,000 to $200,000 plus three years in prison.
Another study at the University of Missouri shows that bottled water increases the growth of breast cells by 78%.” I don’t think humans should pay more money for water that tastes the same as tap water and also hurts the environment just to risk their lives. I don’t think you want to add another symptom leading to cancer; one of our foremost death causes. In addition to the brand-new water bottles having chemicals inside, even reusing the bottles with our own tap water has its disadvantages. Studies show that if water bottles that are made of single-use plastic are reused, then they can produce leach chemicals in the water that lead to bacterial growth. I think that humans should not waste money for single-use items when they got all the water they need at home.
2007). With frog populations dissipating worldwide due to the deadly chytrid fungus, there is increasing pressure to find a natural solution to this problem. Scientists have reason to believe that the poison frog's toxin could provide help in finding a cure to this fast spreading, deadly fungus (Macfoy et al. 2005). Along with providing answers to mass frog extinctions, the mimicry relationships among poison frogs and non-toxic species may prove to be an ideal model for other ecological interactions (Darst & Cummings 2006).
Even if it was successful to cure river blindness the victims were too poor to afford the drug. There was no way to distribute it in these rural areas were the victims were located. In addition, there was a possibility that people would misuse the drugs, which would cause negative side effects and stimulate bad press for Merck. During this time, healthcare costs were on the rise, Medicare and Medicaid reimbursements were limited for companies developing drugs like Merck. Congress was also about to pass an act that would make it easier for competitors to copy and market generic drugs.
Being an invasive species that cause significant economic and ecological damage to the lake, it was apparent that affirmative action had to be taken. After close examination of the actions currently underway, a prominent question comes forth. Are the current efforts and methods used for the eradication and control of zebra mussels in Lake George sufficient for the protection and continuing preservation of the existing ecosystem? Personally, I think they are not. Taking into consideration the fact that one can never really do "too much" to benefit a situation as such, Lake George and it's officials, as well as it's local inhabitants, could be doing a lot more.
In result the introduced species starts reproducing and slowly begins to take over, becoming a nuisance to the environment; and with nothing preying on the new species the invasive species continues to grow. They’re very harmful to the environment because the invasive species disturbs the equilibrium and many of the other native animals living there. Also local areas get infested by the invasive species and after too long the invasive species gets too abundant that they get harder and harder to get rid of. Then eventually it is nearly impossible to get rid of the invasive species. There are some invasive species that have become a nuisance to the U.S.A.
