More depressing news from Africa, and the root cause is political mismangement and courting votes and essentially trying to find a quick solution to problems at the expense of the environment. What is quickly being learned is that then environment is not an infinite sink for our problems: there are limits and when they are exceeded it leads to big problems. In this case so big it is affecting other countries outside Kenya and millions of people. The effects are massive as this BBC article attests.
The bad news: the scale of the problem is massive; the good news: the politicians are actually realising this and doing something about it.
A related note but of little consequence: my wife and I were once on the same Kenya Airways flight as the Nobel laureate Professor Wangari Maathai of the famous Green Belt Movment.
