t the beginning of the 19th century, only 3% of the world’s popula-tion was urban. By 2050 this figure will exceed 70%. Overgrown cities will make environmental and social sustainability and quality of life extremely difficult. We need to raise the stakes: not settle for reducing emissions to neutrality, but rather develop solutions with a net positive impact. Capable of regeneration. Which solutions? Among them are forests in general, and in particular city forests, as they regulate urban microclimates, dampen thermal oscil-lations, filter air pollution, oxygenate, capture CO2, prevent flooding, and project a natural landscape with therapeutic effects on human psychology. Not to mention the revaluation of the city as a healthier habitat. The asphalt jungle is no longer a source of inspiration - not even for rock music. ENVIRONMENT
