Now that i reading posts in this thread, i do remember reading articles about elephants trashing fields with crops. These animals are so incredibly huge(between 3m and 4m height,around average weight is 5000 kg) and strong, that those local farmers would really need concrete walls or dig pretty deep trenches (which on itself are a danger to animals). A simple fence is not going to do it. The same problem applies for 150 to 250kg pure muscle lions.
But how to build cheaply concrete walls that are miles and miles long and on average 4 meters high... Solving a problem is not that easy in Africa but not impossible. But the money...
Yeah, my only problem is how true any of the information she has been told actually is though. Remember, this is extremely corrupt, a bajillion times inflation, severe human rights violating Zimbabwe.
