Chlorofluorocarbon (CFC).
The only pollutant that has increased in emissions since 1970 is carbon dioxide (CO2). This rise is primarily attributed to the burning of fossil fuels for energy, transportation, and industrial processes. Unlike other pollutants that have seen reductions due to regulatory efforts and cleaner technologies, CO2 emissions have continued to grow, driven by increasing energy demand and population growth.
"lead" is the air pollutant that decreased most in 1970 to 1991.
It increased significantly.
Yes, you can eliminate the charcoal canister from a 1970 Nova, but it is not recommended due to potential environmental and regulatory issues. The charcoal canister is part of the evaporative emissions system, designed to capture fuel vapors and prevent them from escaping into the atmosphere. Removing it may lead to increased emissions and could violate local emissions regulations. If you're considering this modification, check your state's emissions laws and potential impacts on vehicle performance.

Australia's population has increased
Between 1970 and 2007, the captive population of golden lion tamarins increased significantly, from about 200 individuals in 1970 to approximately 3,000 by 2007. This represents an increase of around 1,400%, reflecting successful conservation efforts and breeding programs aimed at preserving the species.
The six pollutants regulated under the Clean Air Act are sulfur dioxide, nitrogen dioxide, carbon monoxide, lead, particulate matter, and ozone. Despite a 42% increase in energy consumption from 1970 to 2001, the regulations and technologies put in place to control these pollutants have helped to reduce their emissions and improve air quality in the United States.
increased substantially
Between 1930 and 1970. Roughly speaking, population doubled during such years, but GDP increased over six times from the 1930's levels.
2009 - 1970 = 39.
The nation's divorce rate increased significantly.
