New Zealand debate

A video questioner, making his voice sound a like a sheep bleating, wanted to know why New Zealand farm animals are the only ones included in an Emissions Trading Scheme.

Clark said Labour is ensuring New Zealand meets its international commitments through the emissions scheme. She said she wants New Zealand to be part of the solution to the "horrible problem of climate change" and the country will be more prosperous if we are truly clean and green.

Key says he's committed to finding emissions solutions for farmers and says "we shouldn't be absolutely crucifying our farmers. We're feeding the world".
