Conservation Biology is defined as the scientific study of the nature and status of Earth’s biodiversity. The main aim is protecting species, their habitats, and ecosystem from overly fast growing extinction rates. Biodiversity is defined as the variety of organisms that occupy a specific region. This includes all organisms from that region, the smallest creature to the largest mammals. The earth is a vast planet, which is growing and changing every day. Many things are out of our control, but there are also many things that are within our control. People play a direct impact on the environment as well as the wild life. Unfortunately a lot of our negative actions have led to the extinction of various species. Animals can be broken down into three different species, threatened, endangered and extinct.
Threatened Species can be defined as a species commonly found in an area, that is at high risk of becoming endangered. "A threatened species may have a declining population or be exceptionally rare. Similar to endangered species, the cause of their decline is based and various factors such as habitat destruction, climate change or the introduction of an invasive species to their natural habitat" (Buchanan,M.). A good example of a Threatened Species is the Loggerhead Turtle. They are found globally, preferring temperate and subtropical waters. Loggerhead turtles and their eggs are hunted extensively in many parts of the world. "However, the main threat is from raccoons and wild boars, they can destroy more than 95 percent of their nests" (Angermeier, P.M). They over growing human population is also a threat. The introduction of strange vegetation by humans creates areas that inhibit egg laying and traps the hatchlings from moving out to sea.

Endangered Species are defined as a species that is exists in small enough numbers that it is in the
