'Hope for Planet Earth' is a tour of Christian speakers on the ecological crisis, looking at the science behind climate change from a Christian perspective. The website is here, with full tour dates for the 20 venues. If you're in the Yeovil area, there are dates at Taunton and Castle Cary in early March. There are various well-respected agencies backing it, and it looks worth a visit if this is an issue that bothers you.
It's even more worth a visit if this isn't an issue that bothers you!!
