In July, 2001, delegates from 178 countries meeting
in Bonn finally reached an agreement on measures that
would be taken to ensure that the 1997 Kyoto Protocol
against global warming goes into effect. In this agreement,
a
number of countries, including Canada, may not have to cut
back on their industrial pollution as much, since they
are allowed to count their large amount of forests as carbon
"sinks" that are capable of absorbing carbon
dioxide.
Some experts claim that carbon dioxide
levels are very important to climate changes and that carbon
dioxide plays a major role in global warming. As a result,
numerous approaches have been proposed to lower levels of
atmospheric carbon dioxide. These methods include pumping
the gas into the Norwegian sea, or into porous rock in
Australia. None of the methods suggested are entirely
practical and also do not consider the fact that carbon
dioxide is only one of a number of greenhouse gases.
