on humans cannot be over-emphasized as they are known to affect most vital organs in the body. Heavy metals are some of the component that contribute to the contamination of the environment (air, water, soil, plants etc.). These heavy metals for example lead and zinc have been known to cause a lot of health problems ranging from hematological to neurological problems. Lead can be hazardous to the body in trace quantity because it can affect virtually all the organ in the body. It induces both microcytic
Related Literature Foreign Leptospirosis is one of the neglected tropical disease in Asia and in the world. It is prevalent on slum areas in which stagnant water exist due to poor water drainage system. Due to its association with flooding, it is believed to be one of the most important cause of acute febrile illness during monsoon and post-monsoon season. Outbreaks often occur during these season and farmers, fisherman, sewage and sanitary workers are high risk occupations. (Lobo, 2011) Humans that
Temperature change, genetic engineering, irrigation problems, soil degradation, and deforestation. All the factors at some point are interrelated. As of today, global warming has wide detrimental and useful effects on crop yield and it alters carrying capacity of the crop. On the contrary agriculture effects climate change with release of greenhouse gases such as carbon dioxide, nitrous oxide, methane and other pesticides which affect air, soil, water quality and biodiversity. Millions of species lose
Upton 14310368 C. ‘In order to understand the geography of soil all one needs is a good map of the solid geology.’ Abstract: It would be naïve to assume that a good map of solid geology is the only resource needed to understand the geography of soils. The geography of soil does not depend solely on the solid geology of the biosphere and lithosphere. When one studies the geography of soil it is important to look at the properties of soils including the parent material which is usually the dominating
Soil degradation is a worldwide problem; developing countries in particular are largely affected where many of their activities are directly or indirectly related to the soil. Human population dramatically increases where on the other hand crop productivity declines and so resulting in hunger and poverty. In Africa most economies mostly Eastern, Western and Central Africa are mainly dependent on agriculture with soil degradation being found to be a major threat to overall economic development (McKenzie
beneath them. These warm season grasses provide pathways for birds and small animals and allow for the growth of forbs. There are several abiotic factors that can influence what types of organisms can survive in this type of habitat. A few are sunlight, which has already been mentioned, temperature, wind, soil, and moisture. The wind will mainly only affect the tall grass, because I rarely
agricultural practices have been proposed in order to prevent the worsening of soil properties under long-term monocultures. The quality of the soil depends not only on its natural composition, but also on the changes caused by the human use
economic activity, in as much as products must be moved to markets. Transport and its systems affects economic conditions and growth and in turn economic conditions and growth also influences transport. 3.1.2. Employment A lot of people in South Africa are offered employment by the transport section of the country, usually the department of transport and transport industries. The transport
China environmental quality is severely damaged by agricultural non-point source pollution in recent years. China soil and water quality is degraded by metals and organic compounds. According to Sun B et al. (2012), the main pollution sources from agricultural activities are crop fertilization, pesticides and livestock organic waste. In agricultural area, the groundwater is generally suffered from serious nitrate pollution by crop fertilization. 38% and 50% of counties drinking wells in Yangtze River
Mostly all of the savannas are located right next to the equator, but not the Australian savanna, which is far south of it. The Australian savannas landscape is affected by abiotic and biotic factors, as well as human impacts on land usage. The climate in the Australian savanna which is an abiotic factor are very extreme and occur at the start of May and ends in October. During these months the weather becomes very arid and forest fires become more prevalent. Due to this high volume of forest
