Endangered Animals
  1. Sumatran Orangutan
    1. Theats
      1. Despite legal protection in Indonesia since 1931, orangutans are still captured from the wild and kept in households as status symbols. In some areas orangutans are hunted for food. Investigations by TRAFFIC, the global wildlife monitoring network, shows that lack of law enforcement against this illegal trafficking poses a serious threat to orangutans. Females give birth to just one infant at a time every eight or nine years, making their populations very susceptible to even very low levels of hunting. Experts estimate that even as little as 1% of females lost each year through hunting or other unnatural causes could put a population on an irreversible trajectory to extinction.
      2. Description
        1. The Sumatran orangutan is almost exclusively arboreal, living among the trees of tropical rainforests. Females virtually never travel on the ground and adult males do so rarely. Sumatran orangutans are reported to have closer social ties than their Bornean cousins. This has been attributed to mass fruit on fig trees, where groups of Sumatran orangutans can come together to feed. Adult males are typically solitary while females are accompanied by offspring.
        2. How Are We Helping
          1. WWF works with TRAFFIC, the global wildlife trade monitoring network, to help governments enforce restrictions on the trade in live animals and orangutan products. We continue to investigate the root causes of this trade and encourage stricter law enforcement.
        3. Black Rhino
          1. Threats
            1. Habitat changes have contributed to population declines, but this is a secondary threat compared to poaching. In southern Zimbabwe, privately owned rhino conservancies have been invaded by landless people. This reduces the amount of safe habitat for two large black rhino populations and increases the risk of poaching and snaring.
            2. Description
              1. European hunters are responsible for the early decline of black rhino populations. It was not uncommon for five or six rhinos to be killed in a day for food or simply for amusement. European settlers that arrived in Africa in the early 20th century to colonize and establish farms and plantations continued this senseless slaughter. Most people regarded rhinos as vermin and exterminated them at all costs.
              2. How Are We Helping
                1. WWF launched an international effort to save wildlife in 1961, rescuing black rhinos—among many other species—from the brink of extinction. Conservation efforts have helped the total number of black rhinos grow from 2,410 in 1995 to 4,880 in 2010. We work to stop poaching, increase rhino populations, improve law enforcement and tackle illegal rhino trade.
              3. Polar Bear
                1. Threats
                  1. Polar bears depend on sea ice as a platform from which to hunt seals, rest and breed. For more than 20 years the summer sea ice has been decreasing in size and melting for longer periods of time. Bears must move longer distances to stay with the rapidly receding ice. In most areas, they come ashore when ice melts and rely on fat stores until the ice refreezes so they can go back out to hunt. Some polar bears, especially in the south of their range where sea ice is gone longest, now suffer from malnutrition. In extreme cases—especially females with cubs— they may face starvation.
                  2. Description
                    1. Polar bears are classified as marine mammals because they spend most of their lives on the sea ice of the Arctic Ocean. They have a thick layer of body fat and a water-repellant coat that insulates them from the cold air and water. Considered talented swimmers, they can sustain a pace of six miles per hour by paddling with their front paws and holding their hind legs flat like a rudder.
                    2. How Are We Helping
                      1. Scientists believe that a natural safety net of ice in the High Arctic of Canada and Greenland covering 320 million acres—or twice the size of Texas—may persist longer than the ice anywhere else. Since 1992, WWF has been working with partners to sustainably preserve the rich biodiversity of this region.
                    3. Blue Whale
                      1. Threats
                        1. Like other large whales, blue whales are threatened by environmental change including habitat loss and toxics. Blue whales can also be harmed by ship strikes and by becoming entangled in fishing gear. Although commercial whaling no longer represents a threat, climate change and its impact on krill (shrimp-like crustaceans), blue whales' major prey, makes this cetacean particularly vulnerable.
                        2. Description
                          1. The blue whale is the largest animal on the planet, weighing as much as 200 tons (approximately 33 elephants).
                          2. How Are We Helping
                            1. The International Whaling Commission (IWC) is the body charged with regulating whaling and addressing the vast number of other threats to whales, dolphins and porpoises in our oceans such as shipping, climate change, and bycatch. WWF works to make the IWC more effective in reducing all these threats to whales.
