Pollution : the future?
Pollution : the future? Today pollution has spread in the form of epidemics all over the world.Simply pollution is something introduced into the environment that is harmful effect to our environment, health as well as our life style.Toxic product dump into the water is the eample of pollution. Pollution in general means environmental pollution. There is pollution in a special place in the world problem today. Environmental pollution is having a huge impact on our way of life. There is no place where there is no pollution TYPES OF POLLUTION :
The following are the types of pollution perceived in our environment:
Water pollution : When a substance dissolves in water and destroys the quality of water and affects the organisms living in water,it is called water pollution hermal pollution : Thermal pollution is the discharge of waste heat via energy dissipation into cooling water and subsequently into nearby waterways. The major sources of thermal pollution are fossil-fuel and nuclear electric-power generating facilities and, to a lesser degree, cooling operations associated with industrial manufacturing, such as steel foundries, other primary�metal manufacturers, and chemical and petrochemical producers Land pollution : Land pollution is the degradation of the earth's land surface through misuse of the soil by poor agricultural practices, mineral exploitation, industrial waste dumping, and indiscriminate disposal of urban wastes.
Radiation Pollution : Radiation pollution is any form of ionizing or non-ionizing radiation that results from human activities. The most well-known radiation results from the detonation of nuclear devices and the controlled release of energy by nuclear-power generating plants.
Noise pollution : Noise pollution has a relatively recent origin. It is a composite of sounds generated by human activities ranging from blasting stereo systems to the roar of supersonic transport jets.
Air pollution : Air pollution is the accumulation in the atmosphere of substances that, in sufficient concentrations, endanger human health or produce other measured effects on living matter and other materials. Among the major sources of pollution are power and heat generation, the burning of solid wastes, industrial processes, and, especially, transportation.
Vehicles are a major cause of pollution. Noise pollution and air pollution occur through vehicles. If we use new technology in vehicles then maybe our environmental pollution will be reduced to a great extent. There are new technologies which are important to helping other already in place technologies to reduce pollution. Converters on engine exhaust systems and smoke stacks could be installed with catalytic styled converters to reduce air pollution on vehicles and machines. This is a fix for pre-existing technologies where the investment at the start was overwhelming and people were unable to afford a big upgrade or big change.
Impact of pollution in the future: Impacts on natural systems Over the course of the 21st century, many impacts are expected to occur in natural systems. For instance, changes in precipitation and the melting of ice and snow are expected to increase flood risks in some areas while causing droughts in others. If there is significant warming the capacity of ecosystems to adapt will be exceeded, with negative consequences such as an increased risk of extinction of species.
Impacts on human populations The most vulnerable people are in general the poor, since they have less capacity to adapt, and their livelihoods are often dependent on resources that are linked to climate.
Impacts on specific regions Africa is found to be particularly vulnerable to climate change, because of existing pressures on its ecosystems and its low capacity to adapt. On all continents, water supply and the threat to coastal areas will be an issue. Overall future impacts are expected to be negative, although some positive effects are also expected initially, such as an increase in agricultural productivity at high latitudes accompanying a moderate warming, or decreased heating needs in cold regions.
Magnitude of expected impacts Impacts will depend on the magnitude of the temperature increase. For instance, some crops at mid- to high latitudes will have higher productivity if local temperature increases by 1-3 °C, but will be negatively affected beyond that. If higher temperatures persist after the 21st century it could result in very large impacts. For instance, the large sea-level rise that would result from the melting of the Greenland and Antarctic ice sheets would have major repercussions on coastal areas. The cost associated with the effects of climate change is projected to increase over time with rising temperatures.
Impacts of extreme climate events A projected increase in the severity and frequency of droughts, heat waves, and other extreme weather events is expected to cause major impacts over the course of this century.
Pollution needs to be dramatically reduced because it is destroying the environment, contaminating our food and water, causing diseases and cancers in humans and wildlife, and destroying the air we breathe and the atmosphere that protects us from harmful ultra-violet radiation. It is the responsibility of every living person to protect the environment, and with the population ever increasing, pollution problems are only going to get worse unless we do something about it. By decreasing waste, implementing recycling policies, banning dangerous agricultural chemicals, and developing safe renewable energy we can significantly reduce the amount of pollution going into the environment annually and increase our quality of living
