The greenhouse effect is

counteracted by photosynthesis which removes carbon dioxide from the atmosphere.

made worse by photosynthesis which adds carbon dioxide to the atmosphere

counteracted by the burning of fossil fuels which removes oxygen from the atmosphere

improved by the burning of wood because this adds carbon dioxide to the atmosphere

improved by the addition of carbon dioxide to the atmosphere since carbon dioxide removes excess heat from the earth's surface and reflects it back into space.
