What are the pros and cons of increased environmental controls on Texas' oil, gas, and aerospace industries?

PLEASE HELP AND HURRY.

However, there are two major problems wit this scenario. One is that the large-scale removal of natural gas and oil held tightly in shale rock requires huge amounts of water and also produces heavily polluted wastewater. This, along with leaks from gas and oil well piping systems, could contaminate shallow aquifers that feed many drinking water wells, as well as deep aquifers, unless the entire drilling, extraction, and wastewater treatment process is strictly monitored and regulated to protect drinking water. A second problem is that by burning more carbon-containing oil, natural gas, and coal, we will continue to release growing quantities of carbon dioxide and methane into the atmosphere faster than they can be removed by the carbon cycle. Computer models project that rising atmospheric levels of these greenhouse gases will play a key role in changing the world's climate in potentially very harmful ways during this century.
