The pie chart shows that electricity production emits the most greenhouse gases in the united states.  according to the environmental protection agency (epa), about 67% of this electricity is produced by burning fossil fuels, while more than 90% of the fuel used for transportation comes from fossil fuels.  what changes must humans make to protect the environment from the greenhouse gas emissions produced by fossil fuels?

According to climate experts, it is urgent to fight the growth of the greenhouse effect, which, by contributing to the excessive warming of the planet, threatens its ecological balance. From the reduction of fossil fuel consumption to the geological storage of CO2, many solutions are envisaged to preserve a balance threatened by increasing industrialization and the development of transport.

Reducing CO2 emissions requires simultaneous action on several fronts: controlling energy demand, improving energy efficiency during production and conversion of fossil fuels, replacing fossil fuels with energy containing less or carbon and the establishment of a market for tradable CO2 emissions permits.
A new way to fight greenhouse gases is the capture of these gases from its source of production and its storage in the underground, appears as a promising solution to face the risk of climate change. Major scientific breakthroughs are expected in this area.
