And beethoven is for. Beethoven is for everyone. Beethoven 2022 the 50th anniversary here on d w. Its the worlds 3rd largest industry but that was before the cove in 1000 pandemic brought tourism to a screeching halt. Thats been especially hard for europe the worlds number one travel destination in years past tourism brought regular surpluses to european budgets. Border shutdowns or restrictions have shown just how many jobs are dependent on foreign visitors and its not Just Airlines and Tourism Companies but also hotels cafes and businesses all dependent on bustling travel. But with the full coffers of the past also growing tensions across europe higher living costs gentrification and frustrations for locals in many cities like here in barcelona but also venice and amsterdam. Ever bounce back to its pretend to make highs and could this extended offseason be an opportunity to rethink travel for the future. Hello and welcome to. M c. Its good to have you with us. Maybe a double edged sw
Is still a string night sky is an ever rarest sight for most people on the planet the night looks more like this. We hear means can shield us selves from too much artificial light. But plants and animals especially insects are defenseless against Light Pollution we need someone whos trying to help them the 1st night Protection Officer in a german city. On this autumn evening Sabrina Frank goes out looking for sources of Light Pollution in her home city of fulda in central germany she discovers a brightly illuminated plane tree on the university campus. This gets me reading annoyed people forget that trees have a biological rhythm to the one in the night still. Has all its leaves while the one next to it is bad some call that. Too much artificial light has convinced the tree its still summer grant is germanys 1st socalled night Protection Officer she goes around with a light meter measuring and recording the outdoor illumination 5 laps is the minimum intensity required here for squares
Danger would have been too much water or do with just a little bit more water no wed have had deeper oceans maybe tens of thousands of meters deeper and wed have had no land just one big ocean when it was no surface and no interaction no possibility of environments favorable to life. We can wonder if the fact that earth had just the right amount of water to have 70 percent oceans continents and then interactions was what made life possible for. The palms of hydrothermal springs provide an ideal environment in which the chemistry of life can get started water heat and chemical elements rising from under the surface to air not creamy to primitive earth was definitely chemistry and a dirty Chemistry Lab where you have a ball with lots of components all mixed up with a lot of changing of parameters and condition its a mental book will take on the show. To say. Hundreds of millions of years the molecules mix together rearranging themselves in all possible combinations becoming ever more com

If we just take the time to observe it nature provides us with a fascinating spectacle. Is the planet of life running crawling offline life a balance everywhere. But for all this beautiful diversity to have proliferated earth has had to provide a favorable environment for around 4000000000 years. Played. Then with the conditions which enabled the blooming of life on earth and could these conditions be present elsewhere resulting in alternative ecosystems. Play. In attempts to answer these questions scientists scour the course. Most for signs of life. Theyve built giant telescopes with which to probe the universe and listen to the whispering of the stars but space has remained resolutely silent. Scientists have sent probes to the very edges of our solar system but always sending back has been images of planets inimical to life. Over the last 25 years however astronomers have discovered thousands of incredibly diverse planets in our galaxy alone and. In so many strange worlds with no sig
