Farmers can also add fertilizers to the soil:
The addition of fertilizers to the soil allows essential nutrients to be taken up by the plant which will enhance its photosynthetic activity.
Extra carbon dioxide can be pumped into the green house. This comes from the burning of fuel like paraffin which releases. Carbon dioxide as a by-product.
Plants convert carbon dioxide and water into oxygen and glucose during photosynthesis. Hence, this process can be somewhat beneficial.
Fossil fuels are burnt (expensive) to keep the green house nice and warm.
Burning of fossil fuels to keep the green house warm is not an efficient process because this will deplete the natural resources.
