Sustainable Farming and Butterflies

Unfortunately the Sustainable Livestock Bill ran out of debating time in Parliament yesterday.
The United Nations report, “Livestock’s long shadow”, notes that livestock farming is among the two or three most significant contributors to global climate change on every scale from local to global. It has calculated that from 18% to as much as 51% of global anthropogenic greenhouse gases come from livestock production.

The charity Butterfly conservation reported yesterday that four species of british butterflies have become extinct in the last twenty five years and that butterflies are faring worse than dragonflies, birds and plants. http://news.bbc.co.uk/earth/hi/earth_news/newsid_9184000/9184871.stm

Conservation measures have saved the large blue butterfly but... 37% of our native butterflies are still thought to be endangered. http://www.butterfly-conservation.org/
