One wonders whether the Government, among others, is really committed to climate change problems.

I have written to the leader of every party informing them of a way to stop sheep and cattle from making methane in the rumen and spoken to the Tauranga MP about it. I also wrote to the head of Federated Farmers.

Not a peep from one of them.

This is not some crackpot idea it's a scientific fact. An investment of about $12,000 in a unit to hydrogenate the water of an entire farm would start a research programme on the system.

If the Government can toss millions at so many undeserving causes, surely they could look into this? We could become the first country in the world to have herds and flocks that do not produce methane and save the farmers millions of dollars in taxes.
