Living in harmony with nature is the obvious solution ... BUT, it is difficult. Economies seen as wealthy we can sometimes see the drivers behind ventures: quick profit. Therefore there is a heavy focus on cost-reduction. This means using cheaper materials or chemicals that allow manufacturers to produce more, or save time/energy. Taking a look at the chicken/egg industries in detail can be unsettling. It is easier (and CHEAPER of course..) to buy what is generic (or most common in supermarkets) and so the masses do that rather than expend more effort to find a more suitable/healthier alternative.
