Could low emission cows help tackle climate change?
Scientists have created a climate friendly cow which expels less methane gas than regular animals.
It has been known for some time that cattle are responsible for a large proportion of methane emissions. The gas - which is released 'at the front end slightly more easily than the back end' - is known to contribute to global warming.
Many campaigners have said that reducing meat and dairy consumption is a necessary step towards cutting emissions. But what if the animals themselves were more efficient?
Dr Eileen Wall, from the Scotland Rural College, explains how they created the new climate friendly cows.
