6. Consumption of natural resources and acid deposition
Consumption of natural resources and environmental pollution are closely
related. For instance, Japan is the second biggest copper consuming country
in the world, with consumption of about 1.5 million tones of copper annually.
The great image of Buddha at Nara used about 500 tones of copper. In other
words, we annually consume the equivalent of about 3,000 images of Buddha
in copper. In the past, a large amount of copper was produced in Japan,
but it has been exhausted. Now we import all the copper we use. About 40
per cent of the imported copper is to produce power transmission lines.
Significant amount of sulfur dioxide is emitted through the refining processes
of copper from sulfuric copper. Rivers have been polluted by copper in
these processes. Pollution problems may be happening in countries that
export copper. Comprehensive international cooperation is, therefore, required
to tackle the acid deposition problem.
