Environmental health Unit 38 P1 Explain how human activity can damages the environment For years now we have been warned about human activity destroying our planet and environment. Some of the things that humans are affecting are Climate Change, Depletion of Ozone Layer, Pollution, Deforestation and Extinction of Species. Overcrowding, urbanisation and population growth Overcrowding can affect our planet more than some people think, Overcrowding means more people this means we use more natural resources this means the earth in the end isn’t going to have enough resources to support the growing population. Remember every person on the planet takes up space which could be used for farmland, and forests. People excrete wastes and litter that flow into water systems, and animal habitats, this is slowly polluting water and killing wildlife.
Explain how human interference in the water cycle can affect water availability The water cycle is the process of evaporation, condensation and precipitation of water on Earth including rain water and how it is distributed. Human factors such as forest clearing, urban construction and changes in land use can all affect the distribution of water. Infiltration can be affected by forest clearance. This also affects perlocation and the water table. When there is rain the forests holds a lot of rainfall to the soil through roots of plants.
Increasing urbanisation, growing population, and developing economies are all increasing demand for clean water and the rise in demand is now exceeding supply. This has created conflict between differing stakeholders (someone with financial or emotional interest in an area) within states, countries, and even on a global scale. This is now also causing substantial impact on water geopolitics. The Colorado River is the most heavily used source of irrigation water in the USA. The Colorado Compact was created in 1922 to establish rights between states.
(Document 3) To some, the heavy cost of indentured servitude was too much. “(Document 3) Mittelberger describes the price of indentured servitude as the, "barter and sale of their children as if they were cattle. What made the American colonies a prosperous land of opportunity In the South, "The trade of this colony Virginia is large and extensive.” (Document 4) The rise of large towns is a good indication of the high level of economic prosperity and standards of living in colonial America. “(Document 2) In contrast, Gottlieb Mittelberger writes in his Journey to Pennsylvania that those who can perform manual labor in their own country should, "stay THERE rather than come to America. That opportunity, however, was at the cost of their fellow man.
This, in turn, can affect habitat quality for plants and animals that live downstream. Biodiversity may be lost if aquatic plants and animals cannot tolerate changing water conditions. When large volumes of water are pumped from a stream or river, water chemistry can change significantly with a drop in water level. Temperatures may rise and oxygen levels may drop, affecting aquatic species that don't have a wide tolerance. Biodiversity may also be reduced if invasive species, such as the zebra mussel or golden algae, are introduced into a waterbody during the drilling process.
The places where most of the people live in Chad are where the climate is extreme. The rain is can vary from drought to flooding and torrential rain which can ruin crops (Rural). The land near these conditions is capable of producing crops but the rain fall is either too little or too much. The climate in Chad is different every year as the weather is always changing. This makes it harder to produce foods and to make money which is the two big reasons for the poverty in Chad.
Bobby Kmetz Oct 21, 2010 Research Report #1Topic In the world today there are many things that are affecting are environment and a lot of those things have to do with effecting the land and soil around us that we use every day to grow plants on and use to raise livestock on. With all the damaging things that are happening to the worlds soil that we all know of such as erosion and irrigation of lands one type of soil degradation that is just as serious as all the others is overgrazing. Overgrazing can degrade soil because of the way it is treated by the animals and not maintained by the land owners. In the book Essential environments it briefly talks about what different activities have effect on the soils. It talks about how even though
The primary effected area would be the damage of infrastructure, loss of power, fires and other potentially catastrophic hazards. Much of San Diego is located in low lying valleys and in a densely populated central business district, because of the strong concentration of people damage and loss of life from collapsed infrastructure and debris would be great. According to (Guzzetti& Carrara 1993 ) It is the location to human population that is key distinguishing feature of population risk .Furthermore much of the secondary effects like the loss/damage to property can be severe, according to (californiagreensolutions.com) in the past 26 years an accumulated amount of 19.43 billion dollars of damage has been attributed to catastrophes, and 19.43 billion has been related to earthquake damage. Conclusion Through my findings and research I have found that the two most common natural disasters that San Diego and its outlying areas are susceptible to are wildfires and earthquakes. Although the frequencies for earthquakes are relatively low the possible of catastrophic damage from one is a major possibility during the next 20 years.
The value of work was so great at this time, and probably the biggest contributing factor that helped bridge the divides. The value for slaves in the south was huge because of the weather and conditions they could withstand. In the northeast the agriculture was not as bountiful due to geographical conditions, the north began to have a booming commercial economy. The industrial economy played large parts in the port cities. Every tax directly affected the economy, and affected the workers and merchants; it had a chain effect that controlled every aspect of the world.
Greetings my friends, Family, and people of this nation, as you all know in these past years the prices on Fuel has gone up reaching record highs. Even prices on clothing, food, and paper has been going up and with these hard times around us, how are we to pay for these high prices on everyday items? . Forests are depleting slowly to make paper for use, in doing so we are losing food that come naturally and destroying our planet slowly. What if one plant could help fix out problem, one plant that can grow in any climate, on any part of the planet with little care, that gives back to the earth when it dies?
