... the environment are minimized or the benefits of further treatment are much smaller than the increased cost. In reality, costs or damages resulting from pollution can rarely be assessed in terms of dollars. Federal air- and water-pollution-control laws of the late 1960s and the 1970s established standards and goals to be met by certain deadlines. Amendments to the Clean Air Act ... and the Water Pollution Control Act postponed these deadlines in 1977, however, and further changes were proposed in the 1980s. Primary wastewater treatment involves such physical techniques as screening larg...

Fracking is the process of fracturing rock using high pressure water, sand and deadly chemicals. The efficiency standard would not be a probable pollution standard since cost to communities surrounding fracking operations is higher than its benefits. Cost such as not having fresh ... water, fracking operations in their backyards, and the loss of trees which are Carbon sinks. A safety standard should be used when referring to fracking since it emphasizes the human...

Automakers must conform to the laws and have responding by producing different vehicles like an electric and hybrid cars. The human perception ... which can be obtained from fuels such as natural gas, methanol, petroleum, and oxygen, has zero emissions because the exhaust that is created is pure water vapor. Another benefit of hydrogen is that it is a renewable resource that we cannot exhaust. Because cars, trucks and...
