Negative and Positive Human Impact 

Since the Everglades became a national park in 1947, humans have impacted it both positively and negatively in many ways. First, about 50% of the land belonging to the Everglades is now being used for grazing and raising livestock, farming, or building houses. This is the impact of human development on the Everglades that harms rather than helps the national park. Pollution is also present in the Everglades due to human activity in the cities and runoff water that has been contaminated. The positive human impact on the Everglades is simply that humans are also trying to preserve the park by creating it as a National Park, so that it will not be destroyed. Also, organizations such as the EPA do their park in making sure that the environment is preserved and protected.
