Environmental impacts - Coursework Example While oil shale offers an important source of energy, the processing should comply with the regulations of Energy Information Administration and appropriate measures should be undertaken to combat the impacts. The conventional habitats of the living creatures are encroached upon and this adversely affects the biodiversity in a region. The variety in the species begin to shrink owing to unfavorable living conditions. (Kattel 2003). The gaseous, solid and liquid wastes emitted as a result of the extraction process interact with each other to produce more toxic and carcinogenic effects (Molder 2004). This causes immense harm to the health and habitats of all living creatures, including humans. Due to loss of habitat and a source of food, many species become rare and at times extinct from the earth. Also the extraction site has to be evacuated which leads to loss of homes for the inhabiting populations. Huge amounts of water are required during the extraction process and for cooling down the effluents. The discharged wastes run off into the local water bodies, causing water pollution. This harms the aquatic animals and plants. The discharged water laden with waste products like tar, phenol, etc. often seeps into the soil through a process called leaching and then comes in contact with underground water and other potable water sources. Consumption of such water by plants, animals and humans have serious aftereffects (Tuvikene 1999). The open dumping of solid wastes can create the risks of a fire or an accident owing to the self-ignition of some inflammable solids when they come into contact with certain atmospheric gases (Petts 2009). Few of the gases that are released as a result of the thermal processing of compounds and the combustion of wastes cause a rise in global temperature and lead to an irreversible damage to the protective ozone layer. The above figure shows that the temperatures in the Colorado Basin estimated on average over

Microbiology BIO - Essay Example This virus can only cause diseases only when the host immune system is suppressed because of diseases or medication (University of Maryland Medical Center, 2011). Most of the viruses, fungi and parasites affect the eye due to due to direct introduction. This is through surgery, trauma, transplant from infected grafts or through hermatogenous dissemination to the eye organs. The most common eye diseases are caused by fungi. The fungi yeast Candida albicans causes endogenous endophthalmitis, while the Filamentous fungi accounts to one third of all traumatic infectious keratitis. Also, the patients suffering from AIDS may contract various fungal infections of the eye because of weakened immune system (Clinical Microbiology review, 2012). The Candida spp are opportunistic type of fungal pathogens that resides within the human body. The fungal resides without people’s knowledge and causes various infections such as eye infections. When the body immune system is weakened, the fungal quickly attacks the various body parts. This fungal species has the ability to distinguish between a healthy host and unhealthy host and alter its physiology so as to tack the body (Boston,
