Fir Trees

As the co2 levels rise species of trees are affected differently. Fir trees have an advantage over many and are thriving off of the co2. The growth of these trees has not been affected negatively. As these trees are being studied they are seen to be producing twice as many seeds. These extra seeds are just as healthy as ones with normal co2 levels. Phd researcher Danielle Way from the Duke campus looked at these seeds and saw that they have just as much nutrients as normal. With these fir trees having an evolutionary advantage they are expected to take over grasses and some bush-like plants.
