The world we live in now consists of more people who are more sensitive to the environmental impact, especially when taking their shopping decisions. 

But if we blink our eyes and go back to visualizing the past few years, have you ever wondered whether people were aware of issues such as global warming and pollution in the past? 

Well to my surprise the answer is yes. 

Here is a small timeline of some of the most impactful environmental reforms in the late 1900s.

• 1964: The Wilderness Act passes, setting aside 9.1 million acres to be preserved in perpetuity, “where man is a visitor but does not remain.” 
• 1965: Scenic Hudson Preservation Conference—an alliance of local residents and national environmental groups—challenges a hydroelectric plant at Storm King Mountain in New York. In 1965, the U.S. Court of Appeals ruled that 'aesthetic, conservational, or recreational' interests can bring a lawsuit, which leads to the starting of the growth of environmental litigation.
• 1967: The Environmental Defense Fund was founded by scientists who began litigation to ban the pesticide DDT. A few Yale Law grads seeking to set up “a law firm for the environment” combined with attorneys fighting the Storm King hydroelectric plant, and the Natural Resources Defense Council took shape. 
• 1970: The enactment of the Clean Air Act of 1970 resulted in a major shift in the federal government's role in air pollution control. This legislation authorized the development of federal and state laws to limit emissions from both industrial sources and mobile sources. 
• 1972: The law became commonly known as the CWA and established the basic structure for regulating pollutant discharges into the waters of the
  
  United States. It started implementing pollution control programs such as setting wastewater standards for industries and firms.
