Dr Lehmann, an amazing man, was a recent guest speaker in class.
He uses his medical and engineering skills to design and manufacture inexpensive and highly portable medical machines.
He developed an affordable home-use ultra-sound scanner the size of a flashlight that can remote an image to a medical center or hospital where the picture can be analyzed.
After displaying and explaining other low-cost, small-size, medical innovations; he started talking about another passion of his; Kenya.
He mentioned one rural village that has no electricity, toilets, or local source of water.
The children have the job of walking about a mile to fetch water for their families.
Dr. Lehman took a trip with the barefoot children and noticed that they walked through human feces on the way to the well.
He showed a photo of the well that was a hole a few feet across and a few feet deep, with a dark puddle at the bottom.
He said, “Notice that the children are standing in the water.
This is the very water that the family will be drinking.”
There was an afterthought.
Didn’t these people ---although humble, poor, and uneducated--- have the good sense to not poison their own well?
Aren’t we all born with an innate sense to not allow waste to mix with our life-sustaining water?
How could the elders not instruct the children to carefully avoid stepping in the waste when going to the well, or, to somehow clean their feet before standing in the water?
Then, another afterthought.
Isn’t that exactly what we’re doing to our own precious water supply?
We pour insecticide and herbicides on our lawns.
We broadcast chemical fertilizer on to our greens to make them greener.
Our cesspools seep human waste down into our aquifer.
We flush unused antibiotics down our toilets.
With soiled feet, we stand in our own well.
