a problem also for these water uses in the serengeti. river provides an essential source of water for animals including more than a 1000000 will to beast to migrate here every year the migration brings in tourists and with it income for tons of media. the mar is a post hotel does not use the river as water but the river does give the hotel an advantage i think. the hotel would not be here if it very vocal not to be here as well because they live attract a lot of games anymore so it's trucked a lot of clients a local a lot of privacy to come here because of the animals. making sure those animals get enough water on both the kenyan and tanzanian sides of the border. that's also an important part of the agreement that will be drawn up. they don't know the border that this is done and this is kenya and then migration when they move from setting go to air base found in tanzania they go into kenya. so they always a lot of the whole territory saw we have really a very big task for the 2 countries to make sure that we preserve this reliever. bac

from there it flows over the border into tanzania through the serengeti and into lake victoria. station and large scale agriculture upstream damage and pollute the river and that has an impact here. scientists are collecting data as to form a water allocation plan and facilitate a political agreement between the kenyan and tanzanian governments they want to make sure people on both sides of the border have access to water and avoid any future conflict the current health of the river is an important aspect of the project the scientists examine water quantity ph balance temperature and other factors. we measure these parameters because if we find they're outside of the correct range. then we know there's pollution in the river. that is something that would affect all the life in the river as well as other users like us human beings. to date the water ph is normal but water levels both in the wet and dry seasons have fallen over the years which could be a problem if that trend continues. a problem also for these water uses in the serengeti here the mara river provides an essential

rainfall of just 300 liters per square metre that's the same as in the savannah woodlands of the serengeti and with that zebras rhinos and elephants the forests brandenberg no have to cope with the same conditions. the lack of water increases the risk of forest fires and weakens the trees that makes them easy prey for pests like pine bark beetles. women crisscross the bizarreness hold for when a large number of beetles invade a weakened tree it'll die it's been shown that that is closely linked to climate to higher temperatures and lower rainfall. trees attacked by the pests have to be felled. in 201870 percent more timber ended up on the market than in an average year over abundance was bad for business. often mark. the enormous amounts of spruce on the market meant prices 1st drop by 50 percent and then have began we've now reached price levels that aren't even a quarter of what we would normally get. in the hearts mountains in central germany about a 5th of all trees are so damaged they'll probably die this region has been harder hit than many others in the country. treeless patches are

the mid this park the 2nd to the serengeti park in the i think there now. this is dumbbell region there is a national park in the middle here. the area east full of many species why let him out. and then he said project that. investors coming to come bail out to be given a lot so i'll do what he had noun to do this and i did my kitchen quickly as soon as possible so that the. then vest as can not be looked at it in the center of the park so this is what we are doing but who knows i step bridge or come from the federal i were maybe the kid we don't know but the seed we are trying our best. this is where we have now to now. the park official omar is worried that his small staff can't control the vast area of the park. a few hours later we discover that his concerns appear to be justified. hugh. at a junction there is a road sign. a company named saudi star. what we saw was very disturbing. i wondered why the saudi stock company he's after in that case. it is out expanding into the national park. so i would seriously damage the wide to life and the lessons and

different stuff we don't have archaeology specifically t but a project where you look at ship logs or serengeti looking at animals in addition where we look for planets around other stars and people who are not astronomers who don't have the ability to write a program like i could like those planets around other stars like people with professional astronomy training. it's good to see that exploration in that way. >> archaeology is hard to get to other places it is a field if you are notot able-bodied to deal specifically it can be hard and can we truly democratize just to create something that would work that are on - - archaeologist could use and also dealing with the science so to play an important role to create a platform of where we began development speaking to people like those in the universe we spent a lot of time talking to people of all ages and sbackgrounds in a platform like this the fed users as young as four and five and those in their nineties and older but those that they are connected to is important. now we are redeveloping the platform we have gotten feedback for things they

and we went to stay with this tribe called the samburu tribe and it's out in the, you know, the serengeti your kid doesn't show up here, you wonder, "well, i wonder what happened." over in africa, you think, "did they get munched?" [ light laughter ] so, i can't find my kid. i go up to the samburu little tent city they have. and they have this dung hut. and i'm looking for my kid and i stick my head in and all these samburu warriors with, you know, the neck things on, and the feathers, they're all sitting in there with my kid. and they're watching "walker texas ranger." [ laughter ] they've got a generator, and they popped -- you know, they're chuck norris freaks. and here's the sad thing, i almost said to them, "you know, i know chuck norris. [ laughter ] >> jimmy: no >> i thought, is it sad to name drop with tribal people? [ laughter ] you know what i mean >> jimmy: don't do that. >> they look it up and - >> jimmy: thank god you didn't do that. >> we know, you're needy, captain hairdo we know you know norris. >> jimmy: you're needy >> it was weird. >> jimmy: well that's a great story. >
