Iain plays guitar for Ten Tigers and sometimes we let him near a megaphone.
We all want to make a mark on the world. We don't necessarily want that mark to be 100,000 Bangladeshis dead and millions more displaced. So here is
...and save water.
If that friend is a bucket, then the water you collect can be used to water your lawn, or your vegetables.
Collect all your food scraps together, put them in your composter, and in a matter of months you'll have plenty of nutritious compost that you can use to make more food.
The parts that take most energy to remove from sewage are the nitrates and the phosphates. The compunds that your garden most likes, and that you buy in with fertiliser, are nitrates and phosphates. This is without even considering how sensible it is to use litres and litres of water to move a few millilitres of urea around.
If you instead collect this fertiliser and apply it to your lawn or trees you can save money and have a greener garden. It makes a good compost activator, too.
If you think of any more handy humanity-saving tips, feel free to pass them on to me.
