Red Panda Adaptations-
Red pandas have many adaptations. First, they have an enlarged wrist bone located on each front paw, which serves as a "thumb." This sixth digit or "thumb" is useful for feeding because it allows the pandas to grasp and hold bamboo tightly. Red pandas also have large tails which are often used as a pillow and prevent heat loss. Furthermore, their tails assist them in maintaining balance. For instance, when standing on their hind legs, their tails act as a prop.
Red pandas are also excellent climbers, and they have strong, curved claws. When descending down a tree headfirst, the red panda uses hind-foot mobility. During hind-foot mobility, the red panda rotates its ankle outward, allowing its hind claws to firmly grasp the tree trunk. Headfirst descent has many advantages for the red panda. First, it is much quicker than backing down the tree, and it also prepares the panda to make a quick departure when it reaches the ground.

- Us humans fish for food, which decreases the fishes chances of surviving
- We hunt animals like buffalo and cattle, which also decreases survival for them
- We pollute the water with trash

Burning of fossil fuels and toxic gases produced in factories causes pollution. Air pollution infects the environment and threatens the health of all who inhabit the earth. According to the United Nation "The estimations we have now tell us there are 3.5 million premature deaths every year caused by household air pollution, and 3.3 million deaths every year caused by outdoor air pollution. Effluence from industries, fertilizer run off, and oils spills all damage fragile ecosystems. According to the Water Project, "Nearly a billion people do not have access to clean and safe water in our world." Worldwatch Institution says, "The 450 million kilograms of pesticides U.S. farmers use every year have now contaminated almost all of the nation's streams and rivers, and the fish living in them, with chemicals that cause cancer and birth defects.Pesticides, herbicides, large landfills, waste from food processing industries, and nuclear waste generated from nuclear reactors and weapons deplete our soil of its nutrients and make it virtually lifeless. Usually, contaminants in the soil are physically or chemically attached to soil particles, or, if they are not attached, are trapped in the small spaces between soil particles.

Humans living near the coast have probably always used the ocean as a source of food. However, with advances in fishing equipment, larger ships and new tracking technologies, many fish stocks around the world have reduced significantly. Fish stocks on continental shelf areas are now widely considered to be fully or over exploited. Aside from reducing fish stocks, unsustainable fishing practices can have other negative impacts on the marine environment. For example, some fishing techniques such as dredging and trawling can cause widespread damage to marine habitats and organisms living on the sea floor. These techniques also often capture non-target species (known as bycatch) that are then discarded.
