Energy from the Sun the Earth as heat. Some of this heat energy
is radiated into space, while some of it is trapped by greenhouse gases in the atmosphere and reflected back to Earth. This is a natural process, but in
recent decades, human activities have led to an increase in the amounts of greenhouse gases in the atmosphere which is now trapping too much heat.
One of the main greenhouse gases is carbon dioxide, and extra quantities of this are released/have been released into the atmosphere as a result of burning fossil fuels as a source of energy in power stations, factories and homes. Exhaust gases from cars and lorries result in/have resulted in further emissions of carbon dioxide.
Plants serve to remove some of the carbon dioxide from the atmosphere by absorbing it through their leaves. However, as large areas of forest are felled/are being felled/have
in the Amazon and elsewhere, carbon dioxide is removed in this way.
