Cows are having fewer calves because of climate change http://apocadocs.com/s.pl?1308098016
Warmer springs are encouraging cows to breed earlier in the year so their calves are born in the middle of winter, when they have less chance of survival
The changes have been observed in a herd of cattle in Chillingham, Northumberland, which were first studied by Charles Darwin, the biologist. Dr Sarah Burthe, of the Centre for Ecology and Hydrology, studied the change in breeding patterns over the last 60 years.
She said: "Winter-born calves don't do very well and are more likely to die before they reach the age of one. This suggests that the cattle are responding to climate change but this is having a negative impact on them."
