This is the population found in the wild for each of the following species

• As many as 30 to 50 percent of all species are possibly heading toward extinction by mid-century.
• 99% of currently threatened species are at risk from human activities, primarily those driving habitat loss, introduction of exotic species, and global warming
• The World Wildlife Organization focuses on saving certain species that help sustain other species. They protect wildlife such as pandas, whales, rhinos, marine turtles, primates, polar bears, and big cats.
• Freshwater ecosystems are home to more than 100,000 known species of plants and animals, and are now one of the most endangered habitats in the world as a result of human development, pollution, and climate change.
