ElectricityandControl October 2016Goodday

Every day there is another reminder that things are not as they should be in this wonderful country. For example, there is a worrying sentence in the analytical instrumentation ‘Creaming profits….’ article which reads: Milk will soon be added to South Africa’s list of costly staple foods’. How much more costly can staple foods become? How will people survive if they cannot afford the basics for survival? And what can be done to turn the situation around?

One of the main reasons for the price hike in essentials is the drought. There is a debate as to whether South Africa ranks at 30 or 39 in the category of ‘driest countries in the world’… (as if the number is important)! The more ‘privileged’ among us become aware of the drought – the most extreme in many years – only when we are ordered not to water our gardens and fill our swimming pools. In the rural areas, however, the impact on people and animal life, and land, is immense.

In the 1960s (yes, some of us were even around then) the rain came down in buckets after a national day of prayer for rain was declared…and held.

Perhaps it’s time to do the same.

Let it rain!
