In this essay Moti Nissani shows twin problems of over population and deforestation.
In 1992 over fifteen hundred of world scientists signed a document which expressed their worry about the condition of biosphere. According to them, human activities have caused a great damaged to the natural world. This will endangered human society and the plant and animal kingdoms. Such practices must be checked.
The royal society of the London the US National Academy of Science are also worried about environmental damage. Now more people suffer from cancer, emphysema and Asthma. Many people have lost their hearing power before they are old because of the noise pollution. The rivers, lakes and the seas all are polluted. We are uneasy about poisons in our foods and drinks. Some species of animals and birds are going to disappear, and some have already been vanished. But the number of human beings is rapidly growing. We are using natural resources wastefully. We are producing different type of poison which can not be removed for thousands of years. We pollute even the space instead of preventing pollution, we clean it up after we pollute our land or water. Soil erosion, desertification and deforestation are taking place quickly. As a result, we have to face very hot temperatures, floods, tropical diseases and mass migrations.
A human population always change because some people die while other are born. But the birth rate was little higher than the death rate and the population grew slowly in the past. After industrial revolution, the death rate decreased to a large extend and the population grew rapidly. Now every year there are eighty million people than those of the previous year. In 1951, Nepal's population was nine million. After less than fifty years, the number rose to twenty-three million. By the beginning of twenty-first century Nepal's population will be 24,000,000. In 2026, it will be 46 million and in 140 years the number will be 368 million.
On first site we may think that more people we have the richer we become and that more people may invent more to make more profits. But the finite world is already over populated. For example, can Nepal support 44 million people? more people will need more food. To grow more food we must cut down the forests and there will be no trees. The land, water and air will be polluted. Both towns and village will be crowded. Food production and facilities for health will not grow to the ratio of population growth and it may make crime, ethnic conflicts and warfare more common.
In America some 60,000 people die each year from respiratory disease caused by air pollution. The situation is even worse in Kathmandu. But this situation could be improved by controlling population and pollution. The main cause of environmental problem is population growth. More people use more energy and it will have more pressure on environment. If we can control population growth, we can solve many of the environmental problems. The examples of Germany and Sweden show that population can be reduced. In Thailand, China and Egypt, the rate of population growth has slowed down because of combined governmental actions. The measure cause of this decline are modernization, literacy, media campaigns, easily available contraceptives and equal opportunities for women. We know now how to control our numbers, but we must put this knowledge into practice.
Because of rapid population growth many people in developing countries are forced to cut down the trees in the forest in order to grow food. They are also cutting down the trees to sale them at higher prices. The people of developed countries are also guilty. When they ask for more ham burgers, they Brazilians keep more cows by cutting down the forest. The demand of wood and paper products help people to destroy the forest. Population of different kinds has affected the health of the forest. The problem of deforestation was faced in the past, but now the rate of the destruction is faster.
In the beginning of the century 40% of earth's total land was covered by forest by but now it is about 25%. The destruction of the forest will cause floods, landslide, soil erosion, and filling the river beds.
We may not know the result of massive deforestation what human being can't fell the trees and still hope for better future. We can save the forest by controlling the number of people and by educating them. We can also impose special tax on wood- products. More over some money should be given to those who help to preserve the forest. Reforestation will have bio-diversity, pure wilderness, and it will minimize desertification. Flooding and declines in rainfall the smokeless stove uses less firewood and the people will have more time to pursue study and other more profitable business. If we have fewer people and more trees, we can save planet for our children. For this we need wisdom, courage and compassion.
Question and Answers:
1) Are most winning Nobel Prize winners optimistic about the future of humanity? Why or why not?
Ans: Most Nobel prize winner are optimistic about the future of humanity. They are worried about the present condition of bio-sphere. Human being has caused a great damage to the environment . Te future of human society is dark if we continue our current practices. But if we check them, the living world will be able to sustain life in manner we know. For this, complete changes are necessary. They hope that our urgent actions will safe the future of humanity.
2) What leads Nissani to the belief that the world is facing over population crisis?
Ans: After the world became industrialize the human population started to rapidly. Now every hours we add 10,000 people to our numbers. Nissani is worried by this fact because it will have a direct impact on the natural world. In order to fill more people, more land should be cultivated and more people cut down the trees and cultivate the forest. More over, the growing population has polluted rivers, lakes, air, drinking water and soil. Now about 60,000 Americans die each years by respiratory diseases which are cause by human made pollution. Fourteen Americans dies each year by human asthma which is again made more serious by air pollution. Desertification, depletion of non-renewable resources, acid rain, loss of species, wild species, Ozone layer depletion, the greenhouse effect, flooding, landslides, soil erosion, droughts and weather extremes indicate that the world is facing the problem of over population.
3) What's wrong in his view, with a treeless Nepal?
Ans: If there will be no trees in Nepal, it will have the number of harmful effects after trees are cut down, the top soil will be carried away by rain water and the rivers bed and dams are filled with such soil. It will cause devastating floods in the Terai of Nepal, in India and Bangladesh. After the fertile soil is carried the land will be less productive. Deforestation will also cause landslide. Many species of plants and animals will disappear. It may contribute to droughts and greenhouse effect.
