cities like these make it possible to see the starlit sky again and reset the body clocks of us creatures below to their natural day and night rhythm. darkness not only helps us get a better night's sleep it's crucial for maintaining a balance in nature light pollution poses a serious threat to not tunnel species like bugs however scientists in the netherlands seems i've found a solution to this by creating special refuge areas for the flying mammals and that isn't to keeping the bats safe they also make sure they are rolled in the local ecosystem is preserved. and there's one. and the official line of figures at least 5. far away from the bright lights of amsterdam ducted commute is after

a creature that likes to operate under the cover of darkness. and he is studying how lights are affecting bats. so far his team has found that the 19 species of bat found in the netherlands react in widely different ways. and that's have a very strong response to light there's actually driven by mostly by fear of predators so if you're about that flies very slowly you better hide away and don't show yourself in the light because it's it's risky however if you're a bat that flies very fast it's very agile and you don't need to be afraid that much for predators so you actually like taking away. from the slow flying species and exclude giving it to do these already common. but species and that's one of course not a good thing and domes of biodiversity you actually reducing biodiversity that.

nocturnal species are sensitive to the blue range of light as they have evolved to use the moon to navigate the brighter the blue the more distracting it is to test how species respond to other parts of the spectrum the researchers have put up almost $200.00 lamp posts around the country that shine a range of colors. if you take away the blue part of the spectrum and and compensate by a bit more rats which you actually see here. it may actually be less intrusive for these not the most species not all species may not perceive this like this intense and that's exactly what we have observed. the world over brightness and luminosity are growing at a rate of 2 percent per year. as the night gets more illuminated studies are linking light pollution to destructive natural cycles as well as mental health

and humans. on their own outside eindhoven farmers on a cold and carlos phase are also members of the community fighting for darkness and its bouts for reasons of their own we tried to. kill well you would see the harmful insects in the natural way so we use. insects to cool to kill other insects and that's where also the bats common because birds eats lotsof 1st verse they actually eat the roots of to fruit trees especially the apple trees and so if the bets of schaefer's we don't have those terrible groups in the ground eating our roots to trees so. that's what we like best. that's what is natural best decides and are an essential part of how the ecosystem

of the altered functions. in this farm even has a bad hotel to make the mammals feel extra welcome you can see over here. that that there are better living in the better trial because this is what's over on the move. there excrements they're poor. the community around has installed a special back friendly lights in the area to make sure the animals stay put as night falls. something. around 10 pm the bats check out of the herd and disposed through the farm ready for a meal and to play their role in the ecosystem. maryse donner's is a researcher and signifies that the company in the design the lights around the

orchard. know. he explains that lighting is more than merely installing glowing lamps. so i'm stuck we need lighting but we do solution to it in a sustainable way. show obviously in energy efficiency. in. cradle to cradle type of solutions but also in the direct effect is fighting enough and we have to look tomorrow effect on our own the whole ecosystem and not just on the people. but some districts in the netherlands have in fact become darker as a result of such initiatives as satellite images show giving some of its residents and its resident bats the beloved's night sky and back. like this beautiful birds returning to africa we had 2 of each in the southwest could

a lot of them 5 or 6. we hunt them at night with machetes and torchlight often with the help of dogs while you do things when i see talk to. my baby brother or sister or my mother if you like family to me i d n g o c m has been active in granbury obese since 2010 i sensitized locals is one of its main challenges i maritime police play a big part in the project they supervise the region's waters and clamp down on anyone in the gally hunt and sea turtles. i judge that i max and go have a regular and inspect fishing vessels returning some land. in a depression a depression. there are 2 types of fishermen these

a gun and swift fishing nets so sometimes when they're fishing the catch totals but i didn't do it on purpose saying hello flip flop. as well but there are also liberians who use fishing lines and trust their lines they can cook. if the marine please don't catch them at the fisherman saw the tuttles sea in a property by. 6 maritime police patrol here in addition to monitoring illegal fishing they also raise awareness and distribute special nets provided by the c.m. that enables her to sue a state capture. i these divers have 40 sea turtles but their intentions are strictly scientific demo. marine biologist and will return the reptile to the sea in a few alice sea turtles are a threatened species the research is attach a g.p.s.
