True - In the past twenty years, the EPA has actively worked with state
and national governments to implement environmental laws to help reduce
toxic emissions from automobiles and the industrial sector. Companies
are being held accountable for air emissions, land waste and water
pollutants, they are being made to not only pay fines, but to clean up
polluted areas while developing better techniques which will reduce the
amount of toxins released. We now have an increased use of renewable
energy such as solar panels, windmills and hydroelectricity.
The cardiovascular system transports oxygen to cells through blood and takes away carbon dioxide from the cells.
