FORESTS, GREEN PLANTS AND Photosynthesi



All green plants are autotrophy organisms – it means that they make its own sustenance (potravu).  Plants are capable of very important changes. Its can change carbon dioxide and water (by energy from the Sun) to sugar – glucose. They make it by very complicated process called Photosynthesis. This process is also very important for human’s life and other living organisms on the Earth. The very important fact about this process is that by these changes is made oxygen. Oxygen which is necessary for breathing. Other advantage is that plants use for this transformation carbon dioxide which is very dangerous greenhouse gas.  Thanks to Photosynthesis we can use fossil fuels. Fossil fuels were created from green plants many many times ago – but without Photosynthesis those plants would not exist at all.

So if we think about this we really need plants and forests – Its are necessary for our lives and not only ours. 

Especially nowadays I recon It is very important to consider things like SEPARATING WASTE or buying recycled items (like toilet paper, notebooks, est.) – because by this we can prevent deforestation.
