I'm coming to the conclusion we have too many dairy cows in parts of New Zealand.

Time to cut cow numbers, for future generations, says Jon Morgan on Stuff.

"I know, many of you in the towns reached that point years ago, but be gentle with me. It's quite a step for me, long a believer in dairy farmers' untrammelled right to produce as much milk as they like", Jon begins, and goes on to describe the problem, then conclude, 
"The simple solution is to regulate a reduction in cow numbers.

I say this because it appears the solution already tried – asking farmers nicely, and even giving them some financial help, to fence off waterways and plant riparian strips – isn't working."

This is heresy indeed and will have farmers fuming. Perhaps.

Jon says a lot of bold an sensible things in this article and if you have read this post to this point, I encourage you to follow the link and read the full article. It's very useful.

"I blame farmer-owned Fonterra's headlong pursuit of ever-more milk production for the environmental predicament we find ourselves in. Complicit in this are the governments that have not acted fast enough to apply some restraint."

Good stuff.
