Ryoko, I think it would help if you informed yourself a bit more on the issues. It's fine to feel strongly about things, but you also need to know what you're talking about. Using your own experience or your family's experience only can mislead you - your mum may have been the first to use formula among her circle, but formula has been around in the UK for about 130 years, and in fairly widespread use as National Dried Milk since WW2 (I think this will be the powdered milk your dp was fed on as a baby, thesecondcoming - it existed until the late 1960s I think). About 50 years ago, 'modified formula' came in, where the protein content was changed. In the US, formula was more widespread, more quickly.
We have a massive body of knowledge on the ill-effects of not breastfeeding - not to breastfeed has risks, whether it is Carnation, dried powdered milk, formula.
Women should know these things as part of making a decision. They have a right to decide that the risks are not important to them, because (I believe) mothers should be able to decide how to use their own bodies.
Pesticides are a concern for everyone, but they are also a concern related to the polluted cows who eat the polluted grass....and that's where formula (and all other cows milk products) comes from.
There is a good body of respected science on the presence of environmental toxins in milk and none of the work suggests babies would be better off avoiding breastmilk - not sure if you were suggesting this.
The diet of a human being in the first months of life is important - the baby gets no other form of nourishment, and this is a time of the most rapid organ and body growth. The baby will never depend on good nutrition more, ever in his life. Other aspects - junk foods, for instance - are important too, but babies are uniquely vulnerable as they are totally dependent on one food source only, provided for them. I am not sure why you would deride these facts.
