Ninety-nine percent of currently endangered species are at risk of becoming extinct. Who is to blame? Us. Deforestation, habitat-loss, an introduction of exotic and invasive species, and global warming are a few human-induced problems that have lead to a sixth mass extinction of species. Some of the most interesting and unique animals will be erased from our Earth if we do not alter our behaviors or give a helping hand to the cause. If these facts aren't enough to persuade you, maybe a few images of these species will change your mind --

1. Red Panda

This cute, little panda is endangereddue to its quick decline over the past 20 years. The Red Panda feeds off bamboo and lives in a very specific forest habitat. Recently, the panda has entered the pet trade and poachers are capturing the animal to use for medicine, meat and fur.

2. Asian Elephant

Due to their large size and need for an expansive habitat, the Asian Elephant has been endangered since 1986. Most of their decline is due to habitat loss and poaching. The elephant lives in some of the most heavily populated areas of the world, so they often fight for space with humans. Many elephants are forced into "pocket herds" because of surrounding man-made landscapes which limit their habitat space.

3. Golden Snub-nosed Monkey

Around 10,000 of these brightly-colored monkeys live in montane forests today. Their population is endangeredbecause of habitat loss and deforestation. The monkeys are also suffering from illegal hunting and tourism-related activities.

4. Radiated Tortoise

Native to Madagascar, this turtle has found its home in houses as pets in recent years. This critically endangered species has reduced by 80 percent in the last two generations. Tortoise meat, against traditional Madagascar standards, is now being eaten by newcomers to the area. Scientists estimate the tortoise will be extinct in the next 45 years.

5. Sea Otter

Some of the greatest threats to this endangered species include oil spills, fishing nets, cat-spread diseases and severe weather changes. Overall, the species has declined 50 percent in the last 45 years mostly due to human causes.

After only a glimpse into the exceedingly-long endangered species list, are you ready to put your money where your mouth is? The Wild Animal Health Fund helps veterinarians and scientists to study endangered species and collect valuable survival information. The World Wildlife Fund works globally to connect people with nature [and you can virtually adopt an animal!]. These organizations, along with hundreds more, work to protect the earth and our animals from extinction. Do your part and save these species!
