Bird Flu - Research Paper Example Bird flu in humans is similar to the average influenza, so detecting it and diagnosing it can be, at times, difficult. Symptoms can be a bit more harsh than a typical flu and can sometimes lead to death in those with a weaker immune system. Like the average flu, bird flu can be passed from person to person; unfortunately, while the same medications used in the human influenza can be used to treat bird flu, the virus tends to become immune to the effects of the human influenza vaccine, making it helpless against treating the virus. There are also other varying viruses that come from the bird flu microorganism, so symptoms and the threats on life can differ between which type of virus the person has. Bird flu is a virus that is passed from system to system, whether it is by bird or human. Like all microorganisms, bird flu can be carried by means of hands, therefore being capable of being passed on by merely touching another person that has the disease.

People need to be careful how they handle food, and make sure that they wash their hands after making contact with something that has had previous contact with other hands. This microorganism is a bacteria, so while it may not be seen, it can most definitely be present in an area. This microorganism is transmitted to humans through indirect and direct contact. While it cannot be caught while eating poultry that has been infected by the disease (Mohamed Saif, 2005), it can still be caught by touching surfaces that the poultry has been on or by making physical contact with a bird that has it. Indirectly, bird flu can be caught in the same way as other diseases that are passed on by humans. The microorganism is found in birds and can be passed down to humans; its original environment is within the

Critical Biodiversity Essay Example | Topics and Well Written Essays - 250 words

Critical Biodiversity - Essay Example Each of these many species on earth plays a significant role in maintaining of a stable and healthy ecosystem. However, human activities have directly or indirectly led to a major loss of biodiversity and in turn raising questions as to the need of conserving species so as to maintain a stable and healthy environment. Human activities that directly affect biodiversity include deforestation, pollution and overexploitation of natural resources. Indirectly for instance, human activities have led to climate change which negatively affects other species. Since each and every species plays a significant role in maintaining a stable ecosystem, the existence of each species is vital to life. Human being cannot survive without biodiversity as we rely on it directly or indirectly (De Vere, 2008). Directly, most of the plant species are consumed as food and medicine by humans. In addition, all plants play a major role in changing carbon dioxide to oxygen which is vital for human life. Some animal species are also food to humans, and their existence means a continuous food supply. The importances of biodiversity to mankind are just a few to mention. I agree that the loss of a few species may have no profound effect on ecosystem processes, but there is a need to conserve all species for a better and stable environment. Conservation of biodiversity can include actions like restoration of ecosystems, controlled exploitation of natural resources and the requirement to conserve the species among others. In conclusion, humans need biodiversity for survival since diverse species play various roles in maintaining a stable and healthy ecosystem. As a result, they should conserve the species. I agree that just as our comprehension of social equality has expanded throughout history, our familial and social groups have grown in size. Therefore, our inclusion of the environment ought to become a part of our ethical
