Acid rain

April 12, 2013 · No Comments · ESS

  1. The reason why precipitation in some parts of the world is acidic, is because it is mainly caused by the release of sulfur dioxide and nitrogen oxide during fossil fuel combustion. When these gases are discharged into the atmosphere they react with the water, oxygen, and other gases already present there to form sulfuric acid, ammonium nitrate, and nitric acid. These acids then disperse over large areas because of wind patterns and fall back to the ground as acid rain or other forms of precipitation. This usually happens in countries that burn a lot of fossil fuels, MEDCs in this case.

 

 

  1. Acid rain in most cases affect the aquatic life, usually lakes and ponds get an increase in the acidic level and causes irritation to the leaving species and also death. Most of the effects on forests are subtle. Acid deposition may influence forest vegetation and soils. The acid weakens the trees, making them more vulnerable to disease .

 

 

  1. The first step to reduce acid rain is to conserve energy, for example instead of everyone using their own car, public transportation can be a substitute. There are many ways to conserve energy and avoid using to not harm the environment. Awareness Is an important aspect to reduce acid rain, people should be knowledgeable in order to avoid.

Evaluate the successes of the conservation of the pandas and the shape and size of the land.

 

Sichuan Giant Panda Sanctuaries, home to more than 30% of the world’s pandas which are classed as highly endangered, covers 924,500 ha with seven nature reserves and nine scenic parks in the Qionglai and Jiajin Mountains. So far this sanctuary is the biggest sanctuary built to reserve endangered animals . At the beginning they have failed to make the pandas mate and reproduce because they were held in captivity and in such a small areas. Since they have figured the mistake they decided to expand and house the pandas in larger areas. Form the information provided it seems that panda captivity is pretty successful giving the fact that this captivity holds over 30% of the whole panda population . If this sanctuary keeps developing in this path there might be hope for the pandas not to go extinct.

The geopolitics of israel’s water shortage

December 11, 2012 · No Comments · ESS

Israel water scarcity:

Israel is suffering its greatest drought of the past decade and will have to stop pumping from one of its main drinking water sources by the end of the year. Israel’s water problem comes from population growth and an improvement in quality of life. The drought is the result of the past winter’s poor rainfalls and sharp rise in domestic water consumption, which is rising 4 percent annually.

The crisis has had the greatest effect on Israel’s agricultural sector because water allocations had to be reduced hugely, causing a drop in agricultural productivity . This includes shorter crop growing seasons, loss of agricultural land to coastal inundation, desertification, saltwater encroachment into groundwater aquifers and increasingly common bad harvests due to pests and disease. Going back to the question, if Israel’s water scarcity Physical or economical? Actually it’s both. It’s physical because of the past winters poor rainfall, economical because the quality of life in Israel is rising and that means more demand for water. Most of the water usage in Israel is mostly agricultural, because water scarcity effect the agriculture the most.

The Thylacine (Tasmanian Tiger)

The Thylacine (Thylacinus cynocephalus: dog-headed pouched-dog) is a large carnivorous marsupial now believed to be extinct. It was the only member of the family Thylacinidae to survive into modern times. It is also known as the Tasmanian tiger or Tasmanian wolf. At one point the Tasmanian tiger used to live all over the continent Australia, extending north to New Guinea until south Tasmania. The reason why this animal became extinct is mainly from the humans and also the completion it has with similar species like the Dingo. The Thylacine used to be hunted by humans because of the Australian farmers, the fear that the Tasmanian tiger would there sheep. Another reason is after the European colonization in Australia; new species have been brought to the environment, which allowed unnecessary completion with the thylacine.

 

Amur Leopard

The Amur leopard is a very rare leopard subspecies that lives only in the remote and snowy northern forests of eastern Russians region. This animal used to live Korea and northern china, but now it’s no more excitant in these countries. At 2008 census counted only 14-20 adult Amur leapards and 5-6 cubs. Threats facing the species include habitat loss due to logging, streets, growing civilization, illegal hunting and global warming.

Essay Question (Global Warming and Over population)

June 13, 2012 · No Comments · Uncategorized

Outline the factors which are likely to lead to reduction in human population growth ?

 

Four main factors which lead to a reduction in human population growth rates are :

 

Economics: economics plays an great in determining the population growth. The more developed the country is the less  population growth it will have, because this the cost of living is high and it will cost a lot of money to have kids..

 

Laws: for the example china has enforced the one child policy and so far it’s working well. Avoid the fact that its not ethical or humanitarian but  it basically saved china from a disaster. The problem their must be a government with supreme authority over it people.

 

Education: education the people especially  the people in the LEDC  countries. In developed countries contraception very widely but people in poor countries may not have access to simple contraception methods.

 

 

 

b) Discuss why some of the effects of global warming may be seen  as beneficial to human societies:

 

The benefits of global warming are a lot and some of them are quite useful. Expansion in agricultural lands , scientists say that global will open new agricultural areas in countries like Canada, USA and northern Europe (Scandinavian countries). Another useful benefit is more mining in frozen areas. It is estimated that global warming can transform Greenland into mining powerhouse. Although global warming is somehow harmful  but people  tend to overlook  the benefits.

 

c )Discuss , with two contrasting environmental problems, the techno centric view that technology may provide solution to environmental problem:

 

Techno centric views are Technology can keep pace with and provide solutions to environmental problems. Resource replacement solves resource depletion, also you  Must understand natural processes in order to control them.

Soil conservation and domestic allotment act

April 12, 2012 · No Comments · Uncategorized

On On April 27, 1935 was when the congress responded to the threats of soil erosion by announcing the Soil conservation and domestic allotment act. The act stated that its ultimate goal was “to provide permanently for the control and prevention of soil erosion and thereby to preserve natural resources, control floods, prevent impairment of reservoirs, and maintain the navigability of rivers and harbors, protect public health, public lands and relieve unemployment.”

The Act also gave directives to conserve the soil in the “high plains” – soil that was being raised into huge dust bowls during the 1930’s. This period, known as the dust bowl, joint with big economic problms of the great depression, it was really hard times for the farmers. The result of this act soil erosion had dropped by 65%.

The Act educated farmers on how to use their lands without damaging them, and took immediate action to contain the dust bowl’s effects notably by planting trees and native grass.
