There are about three quarters of a ton of termites (白蚊) for every person on Earth. It now proves that these insects may be helping to change climate and affect man's life.
For years scientists have been saying that carbon dioxide (二氧化碳) sent into the atmosphere by the burning of oil might lead to the rise in temperatures of the whole earth, which was called the greenhouse effect in which the gas prevents the escape of heat into outer space. Now an international team of researchers has discovered that termites produce more than twice the carbon dioxide than oil burning does. And this production, which comes from the insects' eating and digesting of different kinds of vegetables and wood, has risen greatly. This is because man has cut so many trees in order to open more land and thus has supplied large quantities of food for the critters in the form of tiny pieces of wood.
Scientists pay more attention to the burning of oil because it is continuing to increase and so far no effective measures have been taken to reduce the amount of carbon dioxide produced in this way: Production by termites, on the other hand, will not increase much more.
