    Ian Malcolm isn't worried

    So, fish north of Calgary are the usual male/female ratio, but fish after passing through Calgary turn into 80% female.

    Being from Edmonton, I have long suspected this about Calgary.

    I am making plans to move back to Edmonton as we speak. :D

    Although, I do have the wonder what the ratio for the North Saskatchewan river is like previous to and after leaving the Edmonton city limits, especially with what the city has industry-wise within it, not to mention that all the farm/food/hormone issues likely ring similar across the province.

    That we've seen it after Lethbridge and other cities isn't really a shock. I remember way back when in Ontario when there was an article that basically said men better learn to love latex, because the other methods are beginning to make our fertility levels drop. :P

    To be honest, and this is just me, I always find I care a lot more when it comes to hormone and pesticides, etc, and it's involvement with the environment, especially since with the latter a large portion of the problem comes from incorrect use, a lack of education and frequent changes which are so rarely announced or predominantly displayed I find it hard to blame the farmer's at times who use them en masse. The government puts a lot of oversight into it's various agricultural boards which look at subsidies and price setting, but not enough into the general safe use of the equipement commonly used by the folks making our food, who's byproducts run off into water basins, rivers, and lakes. I know a lot of people look first to global warming or the garbage crisis, but I look to the fact that we have other problems developing which are overshadowed and not granted the media attention and hence government assistance in repairing the problems as I would like.

    I'd like my kids to be able to play in a creek with crayfish and minnows and frogs in them... and those have all but disappeared from the creeks I have lived by in my life.
