RE: Why Capetonians Should Say 'No' to Desalination

Thanks, I'll take a look. But I forgot to add to my original comment: even if it's true that lowering magnesium in water can lead to heart disease risk, that's easily fixed with a multi-vitamin. Surely we'd prefer water and a multi-vitamin to drought, strife, and death.

Sort:  

I read an article, and then did some further searching online. It does sound like a lack of magnesium CAN lead to heart disease. Good to know! However, that doesn't detract from my point. Water is far more necessary than magnesium. If desalinated water makes a necessity of life available or significantly cheaper, that's an incredibly positive thing. If this desalinated water lacks magnesium, then make sure to eat your veggies and/or take a multi-vitamin.

The one article you linked to is totally irresponsible in its headline and clickbait: Could desalinated water be killing hundreds annually? Well, no, of course not. The deaths might be exacerbated by a low-magnesium intake. But that does not mean desalinated water is killing anyone. It just means people should start eating more vegetables.

Another way to look at it: how many people would be dying per year if they had no access to the desalinated water? Comparing those numbers is the only way to see which is the better way to go.
