m in the Pacific Ocean

Elevation extremes:

Natural resources: the rapid using up of nonrenewable mineral
resources, the depletion of forest areas and wetlands, the
extinction of animal and plant species, and the deterioration in air
and water quality (especially in Eastern Europe, the former USSR,
and China) pose serious long-term problems that governments and
peoples are only beginning to address
