Several large regions of the world are plagued by
conservation problems shaped around a particular inherent
set of geographical, biological and human conditions which
have been operational for varying periods of time. Typical
of situations facing Latin America are the progress of
economic development in Amazonia with its attendant loss of
rainforest biodiversity, and the Central American
"hamburger connection" involving conversion of forests to
grazing land to support the export of cheap beef to the
United States. Characteristic of Africa is the struggle
with desertification in the Sahel and the terminally
desperate fuelwood crisis there. Europe has its centuries-
long history of urbanization and the deforestation of
Mediterranean lands to contend with, while the similarly
industrialized North American continent must deal with
large-scale wetland drainage, the effects of high-
technology terrain vehicles (swamp buggies, dune buggies,
snowmobiles, motorcycles) on the landscape, as well as
protecting the endangered cacti indigenous to the deserts
from overexploitative commerce.
