History of Green Tech

While green tech has become increasingly popular in the modern age, elements of these business practices have been in use since the Industrial Revolution. Beginning in the early 19th century, scientists began to observe the ecological impacts of coal-burning industrial plants, and manufacturers have sought to reduce their negative environmental externalities by altering production processes to produce less soot or waste byproducts.

In the United States, one of the most important milestones was the Second World War. In order to reduce consumption and waste, more than 400,000 volunteers began collecting metal, paper, rubber, and other materials for the war effort.

Following the war, scientists like Rachel Carson began warning of the consequences of chemical pesticides, while doctors abroad reported mysterious illnesses associated with nuclear radiation. Many point to this era as the genesis of the ecological movement, which sought to preserve ecosystems and resources while raising awareness of the consequences of runaway technology.

Government bodies slowly recognized the importance of protecting environmental resources. Curbside recycling programs became common over the following decades, raising awareness about household waste. The Environmental Protection Agency, established in 1970, set firm requirements on pollution and waste and established mandates for coal scrubbers and other clean technologies.
