We'd already changed all our lightbulbs to energy efficient ones, replaced our car with a hybrid, line dried our clothes instead of using the dryer and took our own shopping bags to the supermarket but this year and especially since lockdown, we (as a family including my 19 year old uni student daughter) have all become vegan, walk to our local High Street instead of driving, replaced toothbrushes with bamboo ones, switched to beeswax wrappers instead of plastic sandwich bags, made reusable face masks for ourselves and many of our friends and family and my daughter made the biggest sacrifice - she stopped buying fast fashion and started buying 2nd hand clothing.
