of can we produce our own rare earths independent of china of changing 90 or 95 percent of all rare earth metals from a single country is not an acceptable situation. due to a. rare earth deposits are not necessarily all that rare they're found on all continents not just in china you delight or is found in large quantities in sweden and greenland for example and could be a good source for rare earth elements but extracting them isn't. easy. stuff is all of a beautiful what's interesting about this process is that we're trying to find alternative sources of rare earths in europe those sources have advantages and disadvantages the u.t.i. like we have in europe has a major disadvantage it has to be pre-processed which isn't the case with conventional sources it's using a conventional process the pulverised or would come together and that's why it's 1st treated with our hydrochloric acid it's expensive but can be used on a large scale. recycling could also be another viable solution for ending the near monopoly on the global production of rare earth. wind turbines electric motors and hard dri

also been untapped like greenland and so who needs rare earth minerals china needs rare earth minerals to do what to make things like cell phones because it goes into things like lithium batteries and some of the component parts of cellphones so there is this subtext going on right now it's very similar you talk about old empires how it used to be a just a scramble for resources there is an there is a scramble for resources happening now the interesting thing is that the scramble is shifting away from oil and gas because i think for oil and gas the scramble is to find ways to keep other people's oil in the ground you want to keep iran's oil in the ground and off the market libya's oil off the market in the ground same thing with venezuela but when it comes to things like rare earth and potentially uranium there is a scramble to acquire those or to acquire access to those and that is apparently one of the expects the nation some people have for us why we're still a united states is still afghanistan and would certainly explain why there are some salivating over greenland i take your poi

zone the low for earth masses and 10 before you know for earth radio and 10 earth masses where we could measure that usually they're what gas planets but this one could be rocky. and it's called super earth because it's so small it's because it's so small the planet itself is so small so what we have in this in the solar system is earth and then the next biggest planet is neptune and there's nothing in between ok for the exoplanets we find a lot of planets in between with not one earth radio but to earth right at 3 a thread and for us regular and for those usually we could not detect the atmospheres yet and that's the 1st one and it's 110 light years away from bus no we were in the newsroom trying to grasp how far that is or how long if we could travel at the speed of light so what would happen 1st would we be able to get to super earth 1st or. would bricks it happen 1st i mean if he'd put it like a minister i mean can we imagine how far away the planet is we cannot travel that right i mean that light needs 110120 years to get there nothing can travel faster than light unless we find a

taylor: there is a rare earth metal etf because this is bloomberg. 20% of this is rare earth so it gives us a gauge of where we are. march 2018, the start of the trade fight, and on top you are looking at the price of the etf falling as investors are concerned about demand for these products that make a lot of consumer electronics and batteries. very interesting on the bottom in blue, you have fund flows into that etf. you are seeing investors really buy into this. i bet, maybe hoping the tariff fight will be resolved and they won't see tariffs on the rare earth metals. carol: a great illustration of what has been going on. rare earths also help explain why president trump is interested in taking greenland off of denmark's hands. editor julian goodman breaking that down. >> from the greenland perspective, it is important for them to develop this mining operation because they have been trying to become independent from denmark for a long time. they achieved a big step in that in 2008 and passed a referendum that devolved more powers to greenland and now they need to develop the economy th

you took pictures of some of the rare earth minerals. the potential, it seems like there is an awful lot. jillian: one of the images we have is an image where we have rocks that are glowing fluorescent under black light, and this mineral that we are seeing that is glowing indicates the presence of rare earth metals. you can see a lot of them going and there's a lot of potential for mining. carol: what is interesting is that there has been mining in the past. jillian: denmark banned uranium mining as part of a nuclear nonproliferation action, and that was, to be overturned in 2015, but that operation has not gotten started. carol: there is one town that everybody is focusing on. jillian: the area around it is particularly rich in these minerals. carol: you guys are working on stories. you have been working on this for a while. just over the last couple of weeks we are talking about greenland because of president trump and his interest in it. jillian: it fell into our laps. carol: what do you think in terms of our audience, viewers, and li

we talking about when we talk about rare earths? we are talking about the periodic table of elements. greenland, donald trump's preferred acquisition, it is so resource rich that one of the reasons that i think it become such a fascinating topic is because it is packed with the future of where we think these rare earths will come from. carol: i was thinking about how it was the building blocks for so much. but we think about it differently, especially in this climate change environment world. we look at it in a different way. joel: carbon is one of those elements as well. carbon is an absolute war course. there are a lot of elements that are totally useless or that we do not have uses for it yet, but there is carbon which has more potential in terms of how we are able to sequester it and build things in the future. so, yes. carol: not done with it. jason: one of the ways that this is the joel weber "businessweek," it is very character driven. you have people through which you tell these stories, entrepreneurs, people who you are not

cronkite made the first earth day in 1970, a major national event. the media could make a difference when they were bringing cameras all over earth day so much so that by the end of that year nixon was forced to create the environmental protection agency in 1970. the mayor of california, the counterculture adopted different things from going into space and you got the whole earth catalog and like many of today's entrepreneurs like steve jobs or jeff bezos, they are all about the moon. apollo had a big effect on a certain group of tech people. that is why many of them are trying to get into space as an occupation or financial investment. they are into it. >> host: you brought us back to earth from taking us to the moon and back, thank you, douglas brinkley.

one thing about life on earth is, earth is three-quarters water. there is enough water on mars to stay -- sustain a population there. >> very good question. and all of the studies continue to show that there is water, not only at one of the poles and of course it evaporates during the change of the seasons, but in the -- you might have seen some of the great photos that were taken from different times apart where you're looking at crater and seeing a stream of -- probably mud and slush, but kind of going down the crater, that's clearly a liquid of some sort, and the only liquid could be is water. it's not carbon dioxide cannot exist at a liquid and water can, at least with -- if a its mixed 'with the rocks. looks as if that's going to be upon. just don't now how much of it is there. and i'd also add that one over the cool things about technology is that you figure out ways to use scarce resources better, and so i suspect you'd see a lot of -- a lot of the recycling stuff in this country is a boondoggle and a waste but i suspect you probably would f

what is the gravity on the moon is like one sixth of the earth, what is mars? it's about 38. i want to end with this. this is in fact the 50th anniversary of the first landi landing, and i've argued for some years we should have a human achievement today. i'm curious why the united states patent visited, for 50 years let me finish real quick we should have a human achievement today july 20 would be a good day for that because of some of its one of the greatest achievements in history, going to the moon. i would love to see every student trying to understand everything that went into going in the moon. those of you that are interest interested, the best is charles murray and catherine cox apollo the race to the moon and if any of you are interested in the individuals who put us there, it would be great to have a human achievement day where we celebrate how do we do that. for those of you watching on tv perhaps, we are in las vegas right now. it's 110 degrees outside. i'm comfortable here because of the air conditioning. where did that come from? there was this guy over 100 yea
