The most common reason species become endangered is due to habitat loss. Logging, mining, cattle ranching and oil development are just a few of the activities that contribute to this.
In some cases, a species becomes endangered because other plants or animals have been introduced to their ecosystems. These additional species may compete for resources or carry diseases that kill native species.
Population growth and pollution also put plants and animals at risk. When the population of an area expands, there is a greater need for housing and food.
