Spring has sprung, a little bit early in 2023. On the 16th of March in the vicinity of Paris, where Caillebotte designed his impressionist garden. It is still 4 weeks until Easter. The spring flowers will hardly survive until then. Hence, we prepare for an early summer, nice because of less heating, but the vegetation is suffering in the region due to the lack of rain. Hay fever for millions of persons will start early this year as well. The damages from a fire in the nearby forest “Sénart” from 2018 have still not really disappeared. It is expensive and needs a lot of workers, equipment and knowhow to avoid the same old mistakes of planting mono-cultures of trees again. When will they ever learn, when will they ever learn.
