RABIES-EPIDEMIOLOGY, PREVENTION, AND FUTURE RESEARCH Rabies is caused by a RNA virus, survive in nature by a number of animal reservoirs. Rabies virus infects the central nervous system, resulting in progressive encephalopathy and ultimately death in infected human. Globally, the risk of rabies for humans is great in areas of the developing countries where dog rabies is common. Where rabies in dogs has been eliminated or otherwise controlled through vaccination programs, the disease can be maintained by wildlife. Wildlife primarily helps in maintenance of transmission cycles are carnivores and bats.
When the parvo virus attacks and irritates the lining of the intestines, it causes: 1. diarrhea that often has blood present 2. vomiting 3. loss of appetite 4. depression 5. Dehydration results from fluid loss from vomiting, diarrhea, and not drinking. 6. Another serious concern in parvo infection is that the virus attacks a dog’s white blood cells (cells that protect dogs from infection). When a decrease in white blood cells happens, this makes him/her susceptible to life-threatening infections such as
It may seem like our world is getting more polluted and it is! Pollution damages all aspects of the environment including air quality, water quality, soil quality, food quality and quality of life. According to DoSomething. org, each year 1.2 trillion gallons of untreated sewage, stormwater, and industrial waste are dumped into US water. At this rate, many people are affected.
We can read about global worming, about different kinds of diseases and decreasing fresh water. Water pollution is the largest cause of death and disease on the world.The Earth is covered with around 70% of water.Water pollution is caused by littering water, releasing chemicals and by oil tankers witch sometimes sinks and that is cause to a big oil spill (in the sea). Effects are animal’s extinction of fishes and decreasing of fresh water. Sea level is rising because ice caps are melting. Because of that are floods increasingly common.
Is there any other planet around that can welcome us like our planet Earth? We have killed our only chance of survival, our planet. With the increase of population, pollution, climate changing ozone layer depletion and much more harmful issues. Every day our environment is getting worse and this causes many problems that humans and animals are facing. There are many reasons for these problems.
WHO reports that there are about 1.3 million to 4 million cases of cholera reported around the world annually. The disease is also responsible for death of about 21,000 to 143,000 people per year. (http://www.who.int/mediacentre/factsheets/fs107/en/) Cholera was once a pandemic disease, causing death of millions of people. Today, cholera exists in regions that are developing but is easily
Pollution, everyone complains about it. So what is it pollution? It happens when impurities contaminate the natural environment; which causes about changes that affect our day to day lifestyles negatively. Pollutants are the main elements or components of pollution which are usually discarded materials of different sorts. Pollution disrupts our ecosystem and the balance in the ecosystem.
This is due to their carcinogenic and toxic properties (ATSDR, 2013). As the strict legislations have been introduced by various environmental protection agencies in the developing countries, the removal of heavy metals from water and wastewater becomes the subject of considerable interest in recent years (CPCB, 2008; WHO, 1996). Manganese, nickel and copper are the common heavy metal contaminants and pose significant threats to human health. Manganese poisoning causes various severe health problems in vital organs of humans such as neurological disorders and harmful impact on human respiratory tract due to prolonged inhalation of Mn(II) (ATSDR, 2012). Gastrointestinal distress, pulmonary fibrosis and skin dermatitis are the most noted diseases in addition to lung and kidney problems associated with Ni(II) ion poisoning (ATSDR, 2005; US EPA, 1986).
Not only air pollution is causing this problem but water pollution, climate change and global warming too. These effects of Pollution are causing huge impacts on life on Earth including the complete extinction of multiple species. How many more lives do we have to lose, in order to to take action for this problem? This essay will completely explore and reveal the history of pollution and alternative energy, along with the effects and solutions to solve this terrible problem. Pollution has been around for years but the real question is when did it really start?
Extreme Weather is one of the causes that can definitely wipeout humans of the face of Earth. Extreme weather consists of natural disasters that we see in regular life for ex: floods, earthquakes, wildfires, landslide, tsunamis and many other disasters. These disaster kill people, but if we fail to prevent pollution we will create disasters that will take millions of human lives and it will all be our fault. According to “ The World Health Organization” estimates that 160,000 deaths since 1950 are directly contributed to climate change. A major problem right now is Glacier melting which if not stopped will kill way more people than 160,000 and also in a short time.
