Environmental Science in Today’s World Essay

Humans so dominate todays world that at that place is no ecosystem on earth that has not been influenced to a greater or lesser degree of human activities. And, as long as cosmos remain on earth, such influence depart not end. Sustainability will depend on learning to channel our groundss so that we play a positive supporting role as opposed to a detrimental role toward ecosystems (Nebel & Wright, 1993). Environmental risk is a reality of todays world.The seemingly endless supply of synthetic chemicals, consumer profounds, energy, and waste create impertinent risks through chemical contamination, pollution, and environmental degradation. Environmental disasters such as chemical spills or explosions threaten millions of people living in the vicinity of manufacturing or storage facilities. The uncertain risks of global warming and ozone depletion loom ahead. A telephone ex transmute factor of environmental risk is that it is usually involuntary.People do not choose to ingest c hemical pollutants such as pesticides or industrial solvents in their food and water, to undergo workplace exposures to dangerous chemicals, to breathe bemire air, or to experience radiation exposure from nuclear fallout or faulty nuclear power plants. These environmental risks pose a uncomparable problem to regulators charged with protecting the humans wellness. Limited information may be available on the health effects of these risks. Consequently, in an effort to protect the publics health, various government agencies study these authorisation hazards to determine the level of risk they pose.This effort to understand these risks, and to quantify their opposition on human health, is the field of risk analysis (Moore, 2002). The scale of human occupation and transformation of the environment is now truly global. The adverse health effects of this ignorance may have been limited, as the environmental damage was on a local scale. However, in todays world our activities ar havi ng an impact at a global scale, and global environmental change will become a major theme in public health research, social policy and development, and political advocacy in the twenty-first century.The conceptualization of the environment as a global public good for health should go some way not only in increasing an appreciation for this heritage and dependency, but should also enhance the embrasure between research and policy. This increased awareness and interface between light upon stakeholders might lead to effective action to ensure a sustainable future for current and future generations (Hester & Harrison, 2002).
