New movements are tackling common environmental issues in
Latin America – they have a lot to do.4
Between
1972 and 2000 the urban population rose from 58.9% to 75.3% of the
total.
Air
pollution affects more than 80 million people in the region and
is the main cause of 2.3 million annual cases of respiratory disease
in children.

The
region has more than 30% of the world’s total renewable water
resources. But in 1995 27% of the population had no easy access
to it.
The
region has nearly a quarter of the world’s forest area containing
160 million cubic metres of wood – a third of the world total.
The
rate of deforestation is the highest in the world; of the 418 million
hectares of natural forest lost during the past 30 years, 190 million
were in Latin America.
Latin
America and the Caribbean:
change in forest area 1990-2000 (million hectares)
Total land area 2,017.8
Total land forested in 1990 1,011.0
Loss of forested land 1990-2000 46.7 million hectares
Latin
America has 7 of the world’s 25 biologically richest ecoregions,
containing between them 46,000 plant, 1,597 amphibian, 1,208 reptile,
1,267 bird and 575 mammal species.
As
a result of habitat loss, 31 of the 178 ecoregions are in a critical
state, 51 are endangered and 55 are vulnerable.
Soil
erosion affects 14.3% of the land in South America and 26% in Central
America. By 1980, nutrient depletion had affected 68.2 million hectares.
Between 1972 and 1997 the use of chemical fertilizers increased
from 3.7 to 10.9 million tonnes.
