The natural greenhouse effect has been keeping the earth warm for millions of years, allowing life to thrive on this planet. The enhanced or accelerated greenhouse effect, which is what is happening now, is causing global warming and may mean the end of life on earth if we can't slow or stop it.o this  natural greenhouse effect is very useful.    The gases that keep the earth warm are called greenhouse  gases. The most important gas, causing about 75% of the  natural greenhouse effect, is water vapor.
Photosynthesis and why it's important Photosynthesis is plants taking in water, carbon dioxide, and light to make sugar and oxygen. This is important because all living things need oxygen to survive. All producers make oxygen and sugar for the secondary consumers and then the carnivores eat animals that eat the plants. If there is not enough producers to make the sugar and oxygen that all living things need then all living things will die out.
