this is the main human activity that contributes to global warming...
A-massive dumping of pesticides into the worlds oceans
B-high demand and depletion of the worlds oil supply
C-burning fossil fuels
D-increase of levels of chlorine poured into the shorelines

Respuesta :

I believe the answer would be C, burning fossil fuels. Oil and gas is made up of the remains of microscopic plankton. Over millions of years the remains become the carbon-rich coal, oil and gas we can use as fuel. When fossil fuels are burned they release carbon dioxide into the atmosphere, thus contributes to global warming.
