Trees are emigrating. Forests are on the move. Among the epoch-defining shifts under way on our planet, a green wave is also rising. The signs of this are being captured by satellites, as they create maps tracking the movement of vegetation.
Just as man is forced to move by wars and droughts, trees also have to search for more favourable areas, driven by global warming. Native species that have been established in a region for millennia give way to new – better adapted and hardier – arrivals. According to scientists, the forests of the future will be very different from those of today. Until now, these technological sentinels of the environment have been recording the areas laid bare by deforestation, but now things have become more complicated.
The migration of vegetation is speeding up. But, if he has the will, man can help our most ancient trees to resist. One day, the storm could pass.
