Machynlleth is the first town in Wales to declare a climate emergency. Anita pays a visit to see how the local community is coming together to do its bit in the fight against a warming planet. She stops off at the repair café where everything from bikes to old umbrellas is given a new lease of life. She picks her own veg at various help-yourself plots around the town and heads to the Centre for Alternative Technology where she cooks up a feast with the veg she’s picked in a big solar-powered oven. Also at the Centre she checks out the latest designs in solar heating and finds out that everything from cherry stones to bracken can be used to insulate our homes.
