area along with increase the domestic natural gas utilization. 3. The EPA: The EPA‚ under its current authority‚ regulates the water after it comes out of the ground as wastewater‚ but not while it is below the surface. After fracking‚ much of the water resurfaces from the well‚ where it’s considered industrial wastewater. After a study conducted by the EPA in 2004‚ they gave a clean bill of health to fracking. That study was immediately questioned in the current debate and was essentially

EXERCISE 2: Effect of Human Activities on the Lake Ecosystem I. Introduction The ecosystem of a lake includes biotic (living) plants‚ animals and micro-organisms‚ as well as abiotic (nonliving) physical and chemical interactions. Lake ecosystems are a prime examples of lentic (standing or relatively still water) ecosystems. It can be compared with lotic ecosystems‚ which involve flowing terrestrial waters such as rivers and streams. Human activities commonly affect the distribution‚ quantity

Gathering water for African villages is a job placed on the women. They spend countless hours carrying water from distant sources. These sources are often polluted and this continuous effort is an enormous waste of time that could be better used for childcare and education (Wanja). According to J.W.N. Riviere in a publication called "Threats to the Worlds Waters"‚ women and girls in Africa spend 40 billion person hours a year hauling polluted water. Both natural and man-made pollutants have damaged

quality of water required for human use and environmental protection is an important role for environmental engineers. Increasingly severe quality standards for drink- ing water‚ wastewater‚ pollutant‚ and groundwater require engineers and scientists trained in the theory and practice of water and wastewater treatment. In addition‚ environmental engineers must be able to predict the fate of contaminants in multimedia enironments in order to measure the effects of pollution on humans

People all over the world are migrating to cities in search of jobs and cultural advantages‚ especially in Asia. This has resulted in the formation of huge megapolitan areas and surrounding peri-urban environs. In China‚ a 40 million urban area is planned.The effects of cities on people are not well-understood. Cities require huge amounts of energy‚ resulting in large quantities of waste products‚ causing unsustainable environments. Cities are sources of air‚ water and soil pollution. Light and noise
