By Iain Gulland THE most appetising and effective way for everyone in Scotland to save the planet and help overcome the impact of Covid-19 is this: stop wasting food. We must eat to survive, but we also must start taking seriously the fact that binning food is destroying the planet, our only home. The single biggest cause of the climate crisis in Scotland is our ever-accelerating consumerism culture. It’s not widely known that carbon emissions are not only caused by cars and airplanes, but more so the wasteful way we produce, use and discard products and materials. Many people are rightly taking stock of the single-use materials they use, like plastic packaging. We should also be tackling food waste because it is a bigger contributor to climate change than plastic.
