It's Not Only Logging We Have to Worry About?

Some 30% of the planet's land mass is currently populated by trees. Trees are major carbon storage sinks. They also generate oxygen and provide habitats/foods for many organisms. We have been frequently warned of the dangers of illegal logging on biodiversity and global heating. Several bodies repeat the mantra 'we need to plant more trees to counter climate change'. People even think they can plant their way out of responsibility for air or space travel. After wild fires, trees, in many locations, simply used to repopulate. People have, however, started to notice locations where the trees are simply not returning. Trees are replaced in these areas by shrubs and flowers, with a much lesser carbon storage capacity (https://www.theguardian.com/environment/2021/mar/10/is-this-the-end-of-forests-as-weve-known-them). It seems likely, that some places are becoming too dry or too hot to support trees. Trees, in places like Alberta (Canada), the Amazon, the Boreal forests (of Canada and Siberia) and the US Rocky mountains, are predicted to undergo major declines, within tens of years. It seems that trees are not just a solution to climate change, they are major victims. The resulting changes in ecosystems, seem designed to further accelerate global heating. Save our trees!
