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. doctors 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 seas like bugs however scientists in the netherlands seem to have 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 there is also on a figure at least 5. far away from the bright lights of amsterdam ducted commute is after creature now likes to operate under the cover of darkness.

he is studying how lights are affecting bats. so far his team has found that the 19 species of bats found in the netherlands react in widely different ways. and that's have a very strong response to light those 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 it don't need to be afraid that much for predators so you actually like taking away valuable habitat from the slow flying species and extinct giving it to do these already common. but species and that's what course not a good thing in terms 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 brag of 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. and it may actually be less intrusive for these not in a species not those bees may not perceive this light as 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

in humans. and there are 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 tried to. kill well you know the one full insects in the natural ways to reuse. insects to cool to kill other insects and that's where also the bats common because birds eat lots of sherry 1st and the cook shavers they actually eat the roots of the fruit trees especially the apple trees and so if the bets. shaffer's we don't have those terrible grips in the ground eating roots to treat so. that's why we like bats. that's what is natural pesticides and are an essential part of how the ecosystem of

the archon functions that. this farm even has a bat hotel to make the mammals feel extra welcome. you can see over here. there that there are bets living in the better trial because the civil courts over on the move. their excrements their proof. the community around has installed special back friendly lights in the area to make sure the animal stay put as night falls. on the. 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. of maurice donner's is a researcher and signifies the company in the design the lights around the orchard

. you know. he explains that lighting is more than merely installing glowing lamps. so i expect we need lighting but we do should do it in a really sustainable way. so obviously in energy efficiency. in. cradle to cradle type of solutions but also in the direct effect is fighting enough and we have to optimal 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 back. like this beautiful birds returning to africa we had to a beach in the southwest called the water meet another group of people who invest

a lot of time and energy to help keep animals safe is birds are having fun here in this case sea turtles these mining reptiles spend most of your lives in water but often those lives depend on them surviving a treacherous call to the surf after hatching on the sand just as well they've got help us to help them make it safely and that epic little journey. dog mrs fallen in granbury be a coastal village and take the every night these men are out star in the beach looking for sea turtles their wildlife conservation ists. by morning they fixed up around 30 baby turtles found in a nest. the tiny creatures would release here near these rocks. i went on and where i played a bad man who had been an unlucky part of the beach with very many rocks there are

places to take all right so we look at them to the rocky sports where the can hike from we do to the doctor. and the lucky. turtles have many not to our enemies but on learned and. that you got a call to the got on the side there are sharks and fish and on the beach craps all bets and snakes all prey on temple of the pond and then the filthy female sea turtles return to lansing lay the eggs in the sand after 18 months in cubase and the freshly emerged hatch then scott on the cross the beach towards the sea name more than 5 percent will reach maturity the figure used to be even smaller of all the prejudices humans about father worst until just a few years ago sea turtles and the eggs they hunted in eaten in granbury the i always knew him i was

a poacher i would sell lots of them 5 or 6. we hunt them at night with my churches and torchlight often with the help of dogs while you're still days when i see you talk to. my baby brother or sister or my mother if you like family to me. the angio c.n.n. has been active in granbury be synced. 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 illegally hunting sea turtles. was i not seen go away regularly inspect fishing vessels returning to land. in a bit of depression a depression. there are 2 types of fishermen these again the answer fishing nets so

sometimes when they're fishing the catch turtles but i didn't do it on purpose elephant a lot. as well but there are also liberians who use fishing lines and trust their lines they can cook totals if the marine please don't touch them because sharon saw the tuttles sea in a property by and on the eve of a. 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 enable turtles with state capture. i these divers of 40 sea turtles but their intentions are strictly scientific. they're marine biologists 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.

so they'll be able to keep tabs on the turtles feeded and migration habits. i. also highly know almost nothing about their lives in the scene as well as where to spend 99 percent of the time what it is difficult to research the hundreds get. the data collected will help in planning and. a conservation saying for the species ultimately was environment ministry in cooperation with the n.g.i. is working to turn the country's largest sea to 2 nests in an area into a vast moving. it's amazing to think that those cute but helpless little creatures will grow to weigh as much as 700 kilo are you active in animal conservation yourself write and tell us about it you can find us on instagram twitter and facebook that's all for this edition of eco africa i hope you
