population
Human population in the past 48 years has more than doubled its seize, from 2.5 billion in 1950 to 5.9 billion in 1998 . A few month ago the Secrtary of the United Nation declared a baby as the No. 6 billion citezen of the earth. As you may have noticed, human population has reached a size that threatened our environment and the sustainability of the earth. Is the earth bounded to face this number of human? In fact, in the human history, human population increased stably over centruies until the Industrial Revolution. Thereafter, human population began to grow exponentially over decades. Unless death rate rates rise sharply, world population may reach 8 billion by 2025, 10-11 billionby 2050, and 14 bilion by 2100 . To sustain that many of people, the environment has already paid off. Population has a great impact on the environment. Deforestation, agricultural activities, and enviromental pollution, are either entirly or partly caused by the impact of human population. In th!is reseach paper, I will look these impacts, and state some perspective of the ecologists to these problems. AGRICUlTURAL ACTIVITIES IMPACT ON THE ENVIRONMENT Agriculture is not a direct way of human impact on environment. But in order to f

Gardiner, B. 1990. Energy Demands, Gloucester Press, London In the final stage in a slow and insidious process of land degradation and erosion, is desertification which starts with the loss of vegetative cover and ends with the destruction of the the soil's fertility and its transformation into barrin desert. The most vulnerable soils are to be found in the dry tropices . In most people's view, nomadic pastoralism and traditional peasant agricultures are frequently, but quite unjustifiably, blamed as the principal "cause" of desertification. In fact, traditonal farming systems place minimum pressure on teh land. By contrast, modern mechanized farming and the introduction of have led to overgrazing and unsustainable agriculture . Goldsmith, E. & Hildyard, N. 1988. The Earth Report:Monitoring the Battle for After decades of exponentially growth of population, now it is the time for us to sit down and think again that is our environment's carrying capacity enough to sustain this many of us. Environmental issues countributed by growth of population are just a corner of the iceberg. We must take action to make plans in order to confornt the situation, if we want the earth to support our descentants as well as it supported us. Simon, J. L. & Kahn, H. 1984. The Resourceful Earth: A Response to Global onsequences of soil erosion in terms of future productivity and environmental quality, economic assessments using available data for the purpose of public policy analysis must be made. noticed our water resources have heavily polluted already. Energy is essential for survival. Throughout the, human beings need a supply of energy every day. The demand for energy every day. The demand for energy has grown dramatically during the last 100 years, as the world population increased dramatically. Most of the energy consumed today in the industrialised world comes from coal, oil and natural gas . These fossil fuels are the buried remains of plants and animals from millions of years ago. Besides, the rest of the energy demanded, is supplied by hydrppower, nuclear power and some other "new energy
