of daily human activities cause global warming. As I stated before, the main activities include the use of more machines (cars, airplanes, buses etc.) that release carbon dioxide due to population growth, use of non-environmentally safe products (aerosols) and deforestation. As we are cutting down trees the process of photosynthesis cannot take place. Therefore large amount of CO2 are left in the air. So deforestation is the second major factor that causes global warming. On the contrary, there…

“If you look at the evolution and leap forward to 11 years from now, I think we will be using all the knowledge in molecular biology, and cancer biology combined with imaging, It will be images, combined with genes, tumor markers and patient data.” (Liselotte Hojgaard, MD, professor of medicine and technology at the University of Copenhagen) The science of radioactivity has existed for many decades since it’s discovery. While often perceived as a risky and dangerous practice, artificial…

liquids Throughout surgical methods (King, 2011). They Additionally bring a expanded risk for getting to be contaminated with hepatitis b from needle stick wounds (King, 2011). The companionship of enrolled medical attendants (AORN) distinguishes bio-aerosols Also surgical smoke Likewise different dangers for perioperative nursing as those gas holds harmful chemicals for…

In 2013, it was estimated that there are 382 million cases of diabetes mellitus (DM) worldwide, including Type One and Type Two (Diabetes Mellitus: Diagnosis, classification, and pathophysiology, 2015). DM refers to a group of common metabolic autoimmune disorders that involve hyperglycemia, or an excess of glucose in the bloodstream. In all cases for Type One DM, and in some situations for Type Two, patients who are diagnosed must be insulin-dependent. Insulin is a hormone that is secreted by…

of fuels like coal. All these pollution can be observed in winter, due to the combination of all these chemicals and the fog, it is mainly known by the name of smog. Another kind of air pollutants is present in refrigerators, air conditioners and aerosol sprays, these ones are called chlorofluorocarbons, and they aim directly to the ozone layer. One of the adverse effects of air pollution is acid rain. The release of acid gases, produced by factories like sulfur dioxide and nitrogen oxide,…

itself, as Alan Robock describes. In the article, 20 reasons why geoengineering is a bad idea, increased ocean acidification, ozone depletion and the effects on planation are labeled as the biggest threats geoengineering introduces. Spraying sulfate aerosols into the stratosphere correlates to the reduction in solar radiation and diffusion radiation that exposes the impacts on vegetation. Plants are dependent on diffusion radiation which provides assistance to photosynthesize more efficiently…

Imagine what it would be like to live in an overpopulated area. Now imagine what an overpopulated world would be like to live in. In today’s world the population is constantly increasing and will continue to for years. The continuous growth of Earth’s population will eventually lead to a population that is incredibly dense. Over population is when the community becomes so dense that it starts to deteriorate the community and its standard of living. This is an issue that needs to be taken very…

The Paris Act held in Paris in November 2015, seems to quite the worries of many, about the dramatic issue of climate change, while scientists like James Hansen, a researcher on atmospheric physics at NASA that contributed significantly to the discovery global warming, depicts the Paris agreement as a “Fraud, a fake” (The Guardian, Dec.12, 2015). The Paris Act should theoretically represent an agreement, although in reality, there is no real agreement on measures, procedures and timing, in…

Vaccines are used to prevent dangerous diseases that can be not only harmful but also deadly. Vaccines have nearly eliminated disease & help prevent outbreaks. “A vaccine is a product that produces immunity from a disease and can be given by mouth, aerosol or needle injection. A vaccination is the injection of a killed or weakened organism that produces immunity in the body against that organism. An immunization is the process of when a person becomes protected from a disease.” (basics, n.d.)…

It is widely known that the Earth is experiencing reoccurring climate change and that there is numerous of evidence that prove that human activity is responsible for it. Nothing is infinite on earth and the more we abuse it, the less time we have to enjoy it. People rarely take the time to realize the importance of the environment. As humans, we depend solely on the natural resources that Earth provides to us. All of our needs are satisfied by absorbing the resources of nature. This continuous…
