This presentation briefly covers human impacts on wildlife such as habitat destruction and pollution, along with the importance and benefits of wetlands. Most of the imformation leads into several Pennsylvania species labeled as threatened or endangered. Being that my main interests are in snakes, I throw additional color photos of a few PA snakes into the end of the presentation. Hope you enjoy.

1. In Pennsylvania

4. Both AIR and WATER Pollution effect the health and normal functions Of all species. Fumes from household cleaning supplies, car exhaust, factories, nuclear plants, cigarettes and other harmful gases cause respiratory problems. Pesticide, herbicide, Nitrates, and fertilizer runoff flow into streams ending up in larger and all bodies of water. Oil tankers, boaters and other water pollutant emitters effect fish and ultimately all that need water. http://awearnessblog.com/mandar_sengupta/2008/04/ http://www.flickr.com/photos/lenaah/2239440631

5. Habitat destruction is one of the biggest and most immediate threats to the numbers in species. Bulldozers make leveling fast and easy. http://www.flickr.com/photos/7498782@N05/454604243/
