Did you know that chimpanzees use tools? Chimpanzees 'fish' for termites in termite mounds by stripping thin twigs of leaves and poking them into the tunnels in the mound. Termites will grab onto the twig and be lifted out to the chimpanzee's waiting mouth!
Cancer doctors issue warning about ozone
Cancer doctors issue warning about ozone The ozone layer exists high in the upper
atmosphere and provides a crucial shield from harmful ultra-violet
solar radiation. However, the ozone layer is at risk and, despite
declining emissions of CFCs and other ozone-depleting substances,
yearly ozone losses have increased during the 1990s. Thinning of
the ozone layer will not only affect humans; it will also affect
plant and animal life. Springtime Arctic ozone losses could
adversely affect northern plants during their growing season, which
would have effects throughout the food chain. Cancer specialists
now warn that we must actively work to prevent the increasing loss
of the ozone layer, as it will only get worse and may cause acute
suffering through heat exhaustion, increased pollution and
increases in diseases such as malaria and cancer. Although Canada
supports the reduction of greenhouses gases and the protection of
the ozone layer, not enough has yet been done to adhere to these
commitments.
