Hey: Most of the fruits and veggies are now inundated with pesticides. I can call them "healthy yields" to the extent that more is produced than organics not because they're healthy. They are not what they were thousands of years ago. If our pet rats know the difference (trust me they do) between organic cherry tomatoes, organic romaine lettuce and green lettuce vs the whiter stalks (my dog gets those and healthier foods), they're smart enough. Pesticide anything go untouched. They only eat the green part of lettuce. The water is another issue ...Food is not free. Even if you gather it from the wild it will cost you a lot of time and energy. It is hard work and unpredictable that is why man started farming.
Plus, most of the fruits and vegetables we have today have been cultivated over thousands of years to produce large healthy yields. That's a lot of work!
Why should Wikipedia be free? How would they cover the expenses of the business? Should everyone there work for free? How would they feed their families?
