ENVIRONMENT REPORT – Last Wild Places

By George Grow

Broadcast: December 27, 2002

This is the VOA Special English ENVIRONMENT REPORT.

More than two-hundred scientists have completed a two-year study to identify the most natural and undeveloped
areas on Earth. Their findings¹ are reported in a new book called Wilderness²: Earth’s Last Wild Places.

The environmental groups Conservation International and Agrupacion Sierra Madre worked together to produce
the book. Conservation International provided³ money for the project.

The new book describes thirty-seven wilderness areas around the world. Each has an area greater than ten-
thousand square kilometers. The study considered only areas where at least seventy percent of all plants are
native.

There are wild areas on every continent. North and South America are home to the largest number of wilderness
areas. There are sixteen such areas, from southern Argentina to Alaska and northern Canada. Africa has eight
wilderness areas, including the thick forests of the Congo and the grasslands⁴ of the Serengeti. Australia and New
Guinea share six areas. Europe has three areas and Asia has two. The Arabian Desert and Antarctica also are
considered wilderness areas.

The largest wilderness area is the Boreal Forest. It extends⁶ for sixteen-million square kilometers south of the
Arctic⁵ Circle. The Boreal Forest extends across Alaska, Canada, northern Europe and Russia.

The smallest of the thirty-seven wilderness areas is the Sundarbans. It is the world’s largest tidal mangrove⁷
forest. It covers ten-thousand square kilometers of land at the mouth of the Ganges River in India and
Bangladesh.

The study found that wilderness areas cover about forty-six percent of the Earth’s land surface. However, they
are home to less than two-and-one-half percent of the world’s population. Nineteen of the wilderness areas have
only about one person for each square kilometer. Native people usually live in these areas.

Conservation International President Russell Mittermeier helped create the book. He notes that wilderness areas
help to influence the world’s weather systems and rainfall. He says they also are home to many plants and
animals.

Mister⁸ Mittermeier says population growth and the spread of agriculture and mining operations threaten
wilderness areas. He notes that just seven percent of all such areas have some form of official protection.
