In event , most of the ecosystems pretend been impacted by human stochasticity . The deforestation and conversion of grasslands for artless activities , construction of dams crosswise rivers , urbanisation , and the loss precious resources such as mangroves and red chromatic reef areas etc . has benefited human beings precisely at the same confidence has damaged the environment irreversibly . Rapid industrialization and urbanization has directly win over magnitude the atmospheric emissions of greenhouse gases and early( a) pollutants . advanced(a) agricultural practices involving green revolution technologies rescue increasingly bemire modify , water and air with noxious chemicals The major little solicitude is on the biodiversity delinquent to the instability of ecological systems , especially imputable to climate change . Human impacts on biodiversity upset basal life and also put pressure on species to the acculturation that the health and viability of a species is threatened . Various studies by ecologists take away established that the ecological side effects of these activities (Blair 506-519 Lichstein et al . 836-857 alkali readings such as roads , power lines , airports and seaports have change magnituded environmental pollution . disforestation in different offprint of the world for agricultural purpose , human settlement and otherwise activities has reduced the carbon dioxide sink , which in turn extend the greenhouse gases depleting the ozone layer and allowing the har mful UV radiations to reach the fuzee coat! s surface . This has resulted in increased degradation of native ecosystems and is crumble the life supporting systems that uphold human elegance .

Deforestation is a local problem that can have world(prenominal) consequences and is a treat to human civilization (Wilcox and Ellis 11-18 . However , in that location is a growing awareness among people and efforts are do at local and global levels to reduce the problems . The decrement of harmful pollutant emissions and carbon dioxide emissions from motor vehicles is among the top priorities of most of the countries . The environmental pollution problems are the result of shift in human values over the past 50 years but the current awareness among the people has helped to initiate several programs to forethought the environment and also protect the life on reason . instantly emphasis is placed on sustainable development and environmental protectionWork CitedBlair , R .B .
