After the hand in of submission one, we were all told that we lack proof to support the scenario that we are creating in regards of the team project. Here's a research on the man-made factor that has created problem to our nature and environment. Hopefully it will gives enough proof and supportive fact to our scenario.
All organisms depend on their environments for energy and the materials needed to sustain life. However, the human activities have inflicted harsh and often irreversible damage on the environment and on critical resources. Looking at the current situation, the heavy demands on the groundwater have resulted in serious shortages in more than 80 countries, containing 40 percent of the world’s population. Forests are being destroyed rapidly and some critical forest types will be gone in a few years. With them will go large numbers of plant and animal species, which lead to serious effect on medicinal and other health care benefits. A four-year report by the world health organization warned that the change of ecosystem, including changed biodiversity, may also contributes to the spread of new diseases like bird flu and SARS, as well as influencing the risk of transmission of diseases to human. The environmental changes are already affecting human health and the effects could grow rapidly over the next 50 years.
As the earth is finite, its ability to provide food and energy is finite. Its ability to absorb wastes and harmful materials is finite. Looking at the rate of how human exploiting the earth natural resources and do not take environment responsible behavior into serious concern, lack of basic necessities and the spread of new diseases would become a significant cause of human mortality. Equate foresee that in 40 to 50 years time, the world population may deplete to one third of current population.
When the collision between human beings and the natural world is at the verge where it is no longer able to sustain life, for survival human will have no choice but to turn to science and technology to save what is left of humanity.
