biospheres a part of the world's 1st underwater greenhouse project 10 meters below the sea the ninos garden research project looks into forms of sustainable sub aquatic agriculture which cultivated here usually only grows on land. diver journey from tony's you regularly tends to the 40 different plants cultivated here it looks to me frankie and brilliant at the same time it's really hard to describe but by now working every day is a project like drawing every day and i'm so proud of the outcome so far technically . this system is not a plague of all just in the sea but imagine our many early solar on the war can really benefit this is them 6 years ago divers installed the 1st underwater greenhouses at this depth the sunlight is still sufficient for photosynthesis and

of course no insecticides needed in the surrounding sea water is treated and then used to water the plants the project is currently experimenting with various kinds of fruits and vegetables this is a wonderland. of the water advisories style so here you have one this is the means green equals mcgrady's you weigh 100 bodies but you know water from here to the home market is our own view. on the use we are. growing inside and we saw all the. roofs. on the wall there was just flowing down. the small town of normally in north west initially attracts lots of tourists but hardly any of them would guess that this unique underwater lab exists just a 100 meters from the beach promina. 3 times a week gianni fontanes e.

checks the displays at the control center in order to make sure that the greenhouse is temperature and humidity levels are in order. here you can see anything page with the same thing in general circulation of the head because with the map of the different biospheres and all the technology that is powered by solar energy solar panels up here and there when we'll we're trying to be completely green. this tree of life has the cables that connect everything to the outside world. to 2 gardeners normally make diving gear and they're now using some of the same technology in their underwater lab harvest time is set for september. and this is almost radio say. and not just the latest the basil in the next biosphere over is also ready for picking though it's

a unique karate. we actually got to just preserve than a very specific brazil that was grown in a very specific and new system that we are trying out which is the technology to condense faster or saltwater into freshwater. jenny front and easy used to turn these leaves into pesto now scientists from the university of peas and examine the underwater sounds it's hard to say the place is different or not of course the smells is super good but the real difference is inside of the plants because of the station process they need to go through in order to survive to the situation and say the heavy that there is going going on down there. so far the project has cost 250000 euros so underwater basil is still a pricey delicacy but the operator. plan to continue there were i think the most

garden has a lot of pros stable temperature fresh water for free and everything without polluting. sea gardens and no longer just a dream these become real projects that just might lead to more sustainable agriculture. shifting focus now if you look around me it would come is no surprise that the air quality in delhi is the worst in the world. by pollution is only one of the causes for this nearly 11000000 private cars in school to us on tribute to 6.6 percent of belize air pollution a german company has created a tool to help city planners mitigate the adverse effects of pollution caused by increasing traffic. just breathing normally is painful here the air is foul and burns your eyes india's megacity delhi was enveloped in fix smog last november it's

a problem many cities face worldwide even if not quite as extreme as this. of course it often has a lot to do with a geographic location then there's the weather and it depends as well on how people are heating their homes and if you get a calm and stable high pressure system which happens here frequently with no wind blowing then none of the filth gets blown out of the city council. that's just the type of problem siemens is trying to tackle at the crystal pits center for sustainable urban development in london here the expert air pollution reports for cities across the globe are prepared using data collated by tailor made software it's already been tested in london. this tool do not start here. and we can access the data recorded by

a london monitoring station. we are looking at having to take action to counteract the threat of exceeding pollution limits. of their frequently unpopular measures and this tool helps city planners to say ok i'm going to have a problem and 3 to 5 days. that would mean keeping as many cars as possible out of the city those which do enter are charged a fee which increases in line with the amount of harmful exhaust a vehicle emits the cars are identified using london's road toll system which has been in place for 14 years right now you pay 11 pounds to enter the city on a weekday. not just that they come straight off your bank account. basically straight away and in the future that will at least double that might be even more expensive for diesel vehicles. there are no tolls in german cities something else asia's got a head start on in 1975 singapore became the 1st city to levy an entry fee for

vehicles today it's $1.00 of the cleanest cities in asia. on the other hand you have to see that in india or china besides the industrial production which is going on all over this city has traffic also plays a huge role and they won't get their air quality problems sorted out if they don't start taking action on their traffic. and people are increasingly migrating to the cities a global trend siemens highlights in the crystal city's offer jobs culture hospitals it's senseless to keep polluting these increasingly important living spaces with exhaust fumes so which city would alex and ebing house prefer to live in. here in london and london's got a huge debate going on about air pollution and if i think about it probably move to the countryside. an understandable attitude for an expert in pollution levels in

major urban centers. now this is a recurring question in the 21st century how do we make our cities cleaner and greener germinal to promote is doing his bit by building in commercializing the city crews and create electric bike taxi adapted from fictionalization countries what's more it's a. huge it's morning time in the harsh of the german capital. here at the very case by top he said doing good business. there especially popular with tourists who fail of the city tours to drivers offered. still has been operating a bike tuffy for 13 years. this is a super job for me i've always loved cycling and i like to get moving and i get paid for it i'm never bored with it and i get to show people the city and they're usually really impressed with not every job is like that.

he charges $45.00 euros for a tour of the city. but if i want to write i want you happy. now you know you're not a life you're as light as a feather. together the driver passengers and bike weigh about $350.00 kilos. it's an extra boost it's required there's a manually operated electric motor. that's nice to save his breath for all the talking he does during the tour. so it's coming here from here you can get a good view of the front of the right star it's lit up nicely in the evening on. the bike tucks enables passengers to access places close off to conventional taxis and tour buses like just park for example the driver covers a distance of between 30 and a 100 kilometers a day. ikes

are pretty high tech they were designed and built in the southern german state of the very a by a company called bike cycle rickshaws originated in japan. has given them a modern twist it takes 2 hours to charge up the battery for the most or. considering it can ferry 3 people 2 in the back plus the driver. has a range of 60 kilometers it's could replace a car. bike employs 6 people. or should we test the motor and generic stefan cush was designed the bike taxi a quick check to make sure everything's in order before it took over 8 years to develop the prototype. bike taxi will set you back 10000

euros. to sweeten the deal the engineer has to find a vehicle to accommodate. the bike gets a small part of the cost most of the admin knew goes to the driver it takes about 5 months to pay back the value of the bike taxi. stefan cushier began building by tuck the 17 years ago he's even designed a solar powered version. bike taxis can be found in 120 cities around the world including munich tokyo and caravan. some $200.00 by taxis are already on the streets of foreign land. to whom one has just completed his 1st bite of the day. as a session it was really great and everything was well explained i'm sure we'll do it again sometimes 12. or till my it's time to find his next passenger is.

now india has a thriving stand up comedy scene and increasing to as a growing number of women have joined to be using laughs and jokes to touch upon some horrific button topics previously considered taboo for public discussion many of them also have their own shows on the internet our correspondents. caught up with one of them in delhi and found out what it takes to make a box in what is student and all boy scout. lady this is a in the power decision to buy guns an unusual sight at a popular comedy club in delhi the other country maybe even. gone from our division . saying this is the end of the leveling up. is a woman talking topics usually considered like buying condoms for her brother i
