Organic everything from food to cleaning materials to clothing. It started as an interest in the environment, more than my own health. Organic farms are alive with wildlife whilst intensive ones are more like deserts but as I've researched it more I've been convinced of the health benefits too. Not only the damage done by the pesticides etc but the way intensive farming methods mean that food is just less nutritious than it should be.
However, it has to be said that most of what I've read is definitely written from the POV of the organic farmer or environmental campaigner. Who can recommend something coming from the opposing POV?
