An environment is a collection of all living things in a specific area of land or water. Examples of environments are wetlands, deserts, grasslands, forests, and oceans. In this fascinating series, specific natural environments are explored and how man interacts with them.
Forest: Accounting for around 10 per cent of the Earth's surface; forests are important to the planet's biosphere as they retain water, preserve soil quality and provide habitat for many species. We look at initiatives to combat the negative effects of dwindling forest resources.
Wilderness: Wildernesses are ecosystems that are untouched by, or protected from, significant human impact. Some are too harsh to be inhabited by civilization (ex. Antarctica). Others have been set aside as low impact areas, designed to preserve their delicate beauty (ex. National Parks, World Habitat Reserves, etc.).
Mountain: Roughly one quarter of the Earth's surface is covered by mountains. Life depends on the rivers that are fed by the melting ice and snow that form in mountain ranges. Over millions of years these ranges can be formed by volcanoes and/or shifts in the Earth's crust (ex. the Himalayan range, curiously one of the youngest ranges).
Reef: Coral reefs are incredibly bio-diverse ocean formations sustaining an incredible variety of organisms. Reviewed are some of the most remarkable coral reefs on the planet, and how increased human impact can negatively affect this fragile multi-organism.
