Extreme Environments: Tropic (2008)
The tropics of the world feature the broadest range of plant and animal life, and tropical forests use intense sunlight to replenish the atmosphere with oxygen and water vapor. Regions such as the Amazon are referred to as the “lungs of the world”; however, they are under threat from logging and the pressures of an increasing population. Eco-tourism initiatives are being embraced in order to preserve our environment. This episode looks at various tropical rainforests, reefs and deserts around the world.
