Readers offer practical advice on how to move forwards with a global programme of planting trees to tackle the climate emergency
Yes, climate change mitigation requires excess atmospheric carbon dioxide to be absorbed and stored in vegetation (Planting billions of trees ‘best way to save planet’, 5 July). However, the strategy is not as straightforward as presented.
Put simply, we emit the carbon in fossil fuels into the atmosphere as excess CO2. This absorbs heat otherwise leaving the planet. A policy of planting vegetation, especially trees, that absorbs CO2 lessens this excess. So far, so, good; but we must ask what eventually happens to this vegetation?
