Ecosystem Services (original list)

 * Food and fuel - especially important for subsidence farmers and fisherman. Biodiversity acts as a safety net.
 * Provision of habitat
 * Medicines and biochemicals - a majority of the medicines used are derived from plant, animals, or micro-organisms
 * Recreational, educational, and spiritual values - for example, hiking, fishing, gardening, forest monasteries
 * Climate control - size and shape of landscape over large areas affects the local climate
 * Carbon sequestering - greater species biodiversity of plants increases the amount of carbon dioxide removed from the atmosphere
 * Water quantity and quality - dense vegetation reduces erosion and improves water quality
 * Protection against natural disasters - complex patches of vegetation reduce flooding and can give protection from winds and sea intrusion
 * Soil fertility - fast-growing, nutrient-rich plants increase soil fertility; dense root systems prevent soil erosion. Greater species diversity increases soil organic matter.
 * Pollination and seed dispersal - A large number of plants require insects and other animals for pollination and seed dispersal

Black-footed Ferret

 * Black-footed ferret
 * Their main food source

Polar Bear

 * Polar Bear

Hotspots

 * S. America Atlantic Forest

Mangroves
