When the Environmental Protection Agency was formed in 1970, its mission was to protect the environment and human health. Since then, scientists, health experts and advocates have worked to implement regulations aimed at protecting and cleaning the air we breathe and the water we drink. Many of these regulations, which were aimed at cleaning up the air, also helped reduce carbon emissions, which can contribute to climate change – so it was a win for our bodies and the planet.
