Think about the millions of miles of fences that have been implemented by humans all across the world. Fences do everything for humanity. They create boundaries to mark property lines, serve as a form of property security, and even offer some level of aesthetic value in some cases. However, for animals that live in the wild, some fences can be problematic and even dangerous. If you want to protect the property that is dear to you from the surrounding wildlife, it is important to make fencing decisions that will not cause that wildlife any undue harm.
