A2 Model Answer :

Qst (a) Examine the factors which have contributed to the present debate about the environment (30 mks).

Qst (b) critically evaluate, from a religious perspective, the view that the problem of human greed lies at the root of the present environmental crisis (15 mks).

Ans. There are a number of factors which have contributed to contemporary concerns about environmental issues. They include concern about :

  • Population Growth – The ever-increasing population of the world makes corresponding demands on food resources, which are invariably unequally distributed. The number of people in the world will soon break the 6 billion barrier. There is an understandable concern about how many more people the world can support – particularly in terms of resources.

From a religious perspective, the General Synod of the Church of England has urged the Government to consider what contribution it can make to the encouragement of the stabilising of the world`s population so that human beings can live in sustainable harmony with the rest of the natural order and flourish without want.

  • The Problem of Resource Depletion – There is concern that fossil fuels cannot be recycled and cannot be produced by humans, and are thus finite (limited). Air is being polluted and essential environments upon which other creatures depend are also being consistently depleted, along with over-fishing and deforestation.

The U.S.A. uses over 100 times the energy per person than the developing world; most energy is made from oil, gas, coal and nuclear – all of which cause more pollution problems. Chemicals and pesticides are killing off certain parts of the insect chain, causing the emergence of ‘superbugs’ immune to all pesticides, and  also running off into the rivers and water table causing pollution. There is the problem of deforestation – there are less than 20% of the world`s forests left.

In Roman Times much of North Africa was used for growing grain. Now it is the Sahara Desert. Over farming and poor land husbandry have turned a considerable proportion of the world into useless desert.

  • Use of Pollutants such as CFCs (chlorofluoro-carbons)– There are real concerns about the depletion of the ozone layer – due to emissions of CFC gasses – which may cause humans to suffer from additional solar radiation, leading to an increase in skin cancer.
  • Acid Rain – Acid emissions erode the stonework of buildings, kill trees and other vegetation, and acidify the water ...
