its a bit frustrating to read some of these comments.
nais is obviously a complex issue and its a bit much to delve into depth here.
but before passing judgement one must step back and take note and wonder why there is such a strong grassroots backlash against nais, mainly coming from smaller farmers.
if it is truly a good thing, beneficial for public health reasons why would small farmers be opposed?
especially many small famers and associated groups that more often than not are outspoken advocates of creating healthy sustainable modes of agriculture/food production
theres a wealth of information out there that deserves to be taken into account, articles, books etc

i encourage folks to talk to local farmers and friends who are involved in the areas nais would address. go to your local farmers market and ask folks their opinion. NAIS is a very important issue among those of us who live in and around livestock/farm animals for a reason
