All
over the world, strange events have been occurring to the forests. In
Canada and Russia, insects are eating the trees, pine trees
in Greece are desiccating, and other odd events have
been killing forests everywhere. When asked, the scientist still have
yet come to a conclusion. They are positive that the rising temperatures,
a decrease in water, and an increase in the insect population have something to
do with the situation. However, they are not for sure why some trees
are being affected and some are not. Dr. McDowell in New Mexico is attempting
to find the answers. One of his theories are the trees are developing a disease
called hydraulic failure. This is when the water that flows though the trunk of the tree
stops circulating making the tree dehydrate and die. It has proven how close
mammals and plants truly are.
