Yup, only if we could control the people population like the Maasai control their bucks from impregnating the female goats, we wouldnt have an overpopulation problem. You see, there is a contraceptive that is made from cow skin and then slid down to the shoulder area of a male goat. This device is called an olor.
You hadnt heard of the olor before, had you? Now you have. The thing is, you have to kill a cow, then cut off a small piece of hide so you can tie it around a buck to prevent it from ummm ... humping female goats. Yea, it only makes sense to those who need to do it. But seriously, think about the desert ... dry, no vegetation, no water. Ok? Got the picture. Now think of a cow and a goat. Which is better suited to survive such harsh conditions? Wouldnt it make sense to sacrifice one cow to save many female goats from unwanted pregnancies? Man! Those maasai people are smart.
Its only a matter of time, though, before the bucks figure out a way around this. You feel me?
The other option is to separate the males from females. But that requires fencing and more boys to heard the separated goats. You would also need money to buy fencing requirements. Well, if you are a maasai, money is probably not the most important thing to you. Your wealth is judged by how many cows and goats you have. So, why would you need money when you can make the best of what you own?
I am Kenyan and I approve this technology. It has worked for the maasai goats, it should work for everyone else!
