What is one positive effect of environmental-protection laws?

Environmental law, also considered as the environmental and natural resources law, is a collective solution to environmental pollution. An associated but different array of regulatory regimes, now strongly affected by the environmental legal values, aims at the administration of the particular natural resources like minerals, fisheries, or forests.  

The environmental laws safeguard the safety and health of the environments and humans. For example, the Marine Research, Protection, and Sanctuaries Act prevent discarding of waste in the United States ocean waters without authorization, and the Clean Air Act restricts the emissions of pollutants.  

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.
