FUTURE FORESTS MAY SOAK UP MORE CARBON DIOXIDE THAN PREVIOSLY BELIEVED

Ecologists from the Michigan University recently showed results of their  12 year research.  Because the rising level of carbon dioxide in the atmosphere is the main reason of global heating and climate changes on the Earth, scientists made an experimental forest on 18 acre field in Wisconsin and continuously exposed different kind of trees with elevated concentration of carbondioxide and ozone gas.  The research demonstrated accelerated growth of trees on experimental field compared with the growth of the same trees faced with a normal concentration of carbondioxide and ozone. The difference was 26 %.  In the past there was strong belief that high concentration of ozone gas has negative effect on photosynthesis, but this study shows that it is not the case. It seems that plants have some way of adaptation to new atmospheric conditions.
                I think we should have more forests. Trees will absorb all of thecarbondioxide they get, so they are the only way to stop global warming. It’s amazing that they can increase the quantaty of Co2 they soak up. Every house should have at least one tree in the yard in order to stop global heating

  1. It's amazing that we continue to cut down forests at alarming rates even though we know how important they are to our survival! Isn't it nerve wracking?! Great job on this article review!
