Experiments in the Harvard Forest Ecosystem near Petersham, Mass. have shown that if there is too much carbon in the leaves, decomposition slows down, and nutrients are returned to the ground more slowly. Once there are less nutrients in the ground, plant growth will be stunted...
Secondly, Bazzaz has shown in experiments that butterfly larvae that eat leaves with a higher carbon-to-nitrogen ratio than normal are more prone to death. They have a higher mortality rate and grow less than larvae that eat leaves grown from a nitrogen-rich environment. Consequently, insect populations will go down, which in turn may upset the food chain...
...very well turn out that some species of plants and insects may become extinct as carbon dioxide levels in the atmosphere continue to increase, says Bazzaz...
...increase carbon dioxide, plants have different responses: some become more dominant and other less dominant," says Bazzaz. "This could reduce plant diversity and filter down to animals...
Bazzaz proposes that cutting down on fuel consumption could be a significant factor in reducing carbon dioxide in the atmosphere. "We need to be more efficient," he says. "We need to move towards alternative energy sources such as solar energy...
