A Study on Environment and Health: Issues and Challenges

This Paper present the Environment and health influences of energy are discussed according to the  time scale at which they occur. About half of the world households use solid fuels (biomass and coal) for cooking and heating in simple devices that produce large amount of air pollution. Pollution that is possibly responsible for 4-5 percent of the global freight of disease. The chief ecosystem influences relay to charcoal production and fuelwood harvesting. At the workplace scale solid fuel cycles create significant risks for workers and have the largest impacts on populations among energy systems. In communities fuel use is the main cause of urban air pollution through there is extensive difference among cities in the relative contributions of vehicles and stationary causes. Diesel fuelled vehicles, which are more protruding in developing countries, pose a growing challenge for municipal health. The chief ecosystem influences result from large scale hydropower projects in forests though surface mining causes significant damage in some areas. At the regional scale fine particles and ozone are the most widespread health damaging pollutants from energy use, and can extend hundreds of kilometres from their sources. Such deposition is associated with damage to forests, soils, and lakes in various parts of the world. At the global scale, energy system accounts for two-thirds of human-generated greenhouse gas increases. Thus energy use is the human activity most closely linked to potential climate change. Climate change is feared to have significant direct impacts on human health and on ecosystem.
