This week we are focusing on livestock and their impact on climate change. We've heard about the concerns over the number of livestock here in the UK, and today we find out how beef farmers are reducing emissions by growing cattle faster.

An online course has been launched to raise awareness of the importance, and lack of, diversity in UK agriculture. Nuffield Farming Scholarships say farming is one of the least diverse industries in the country in terms of ethnicity, disability and sexual orientation, and one of the barriers to changing that is the lack of understanding in the sector.

The latest government figures show that 60% of farmers are over 55, with 38% over 65 and just 15% are under 45. The reality of that is highlighted by farm sales: Michael Read is 79 and has an award winning heard of Lincolnshire Red cattle, or at least he did until earlier this month when the herd was sold as none of the family wanted to take on the farm.
