A while back, we talked about National Pee Outside Day (April 19 for those of you planning on celebrating next year). Well now it seems this phenomenon is really catching on. Apparently there is a world shortage of phosphorous (a key ingredient in man-made fertilizer). Some experts suggest we only have enough to last 50-100 more years if we continue to use it at the rate we do. Since we all depend on this stuff to grow enough food to feed the world’s population, we could be headed for a really bad situation.

But never fear, pee is here! Guess what one of the main components of pee is? Yep, phosphorous! Turns out we are literally flushing a fortune down the toilet—along with up to 3 gallons of potable water per flush, but that’s a whole different article.

So what’s a phosphorous depleting world to do? Do I really need to explain further? Ok if I must. Capture the pee to fertilize crops, of course. Seems like American’s are a little more squeamish to this solution than other parts of the world. Some of our brethren in Europe are already capturing urine with special dual tube toilets—one for #1 and one for #2.

If this sounds like a solution you can handle, begin fertilizing your own gardens with a diluted dose of #1. Why dilute it? Pee also has a high salt content which can burn some plants. If you’re not willing to dilute, make sure you don’t sprinkle the plants directly, or just do your business on your compost pile.

Sorry ladies this tip is a lot easier for men to follow, but if you are adventurous, you can try it too.

Save water, save phosphorous, save urine, save the planet!
