jeffrey sachs of columbia's earth institute is world renowned for his expertise on both counts. dr. limate change is not just an environmental disaster, but an economic and national security threat. how dire is the threat? >> the threat is already with us. i spent a lot of time in places in africa or west africa near the sahara desert. the if issics says that the dry places get even drier and that's what you see before your eyes when you see the impoverished people that already have too little water, facing broughts and -- fameni. we have countries in collapse and then wars come in. we had that in the horn of africa, i was in yeminand could see the increased consequences of drought, sure enough explosion of violence. but every time i come back to washington, it's very hard to get the attention of our senior politicians until there's explosion. then we end up with military engagement and huge costs and all of that, because we really haven't gotten to the core of the problem, and that is places that are pour and destabilized by climate change are already being shaken. and the fact that

. -- jeffrey sachs. how we can eradicate poverty in this country.do not have a leadership class that takes this issue or these people seriously enough to pull together a plan to make this happen. we all know this. when this country get serious about anything, when it makes anything a priority, it gets done. if we want to go to war, we will find the money. we will print money to go to war if that is what our priority is. one layperson put it this way. all of the american people want the same thing. republicans, a democrat, left, right, black, white, jews, gentile, educated, e literate. there is a leadership vacuum -- vacuum in the middle where no one is stepping up to fight and defend the poor. i hope if he gets a second term that the president as part of his legacy will take this issue much more seriously, since most of us are falling into this and this anyway. one thing i am certain on that all americans are in agreement on, we are not asking to be poor. if we can have some leadership on this. >> unless you are a month or a nun. -- monk or a nun. y

and now we have economist jeffrey sachs.go, in chicago, former foreign policy adviser to the bush administration and current adviser to the romney campaign. >> we have one conservative, including you wearing a women's scarf, and you call poor dan seymour a zealot? >> i like him because he is eager and makes a case for a very difficult candidate. >> ok. so let me -- >> wow. >> jeffrey sachs, i think -- this is fascinating. for economists like yourself, for numbers nerds like miyself that have obsessed over budgets our entire lives and deficits and growth, this is an amazing time we are living in where you've got every government in western civilization trying to figure out the delicate balance between taking care of the debt, which we have talked about an awful lot, and taking care of growth, trying to revive the economy. great britain just went into a double dip recession. and now the shadow chancellor over there is demanding that cameron and osborn apologize. but this battle is being waged in the netherlands, in england, in

jamie redford, jeffrey sachs. you are not going to want to miss it. see you tomorrow night. >>> all right. welcome to "the young turks." we lead with scandal. the "daily show" is being boycotted by conservatives because of this joke. >> maybe women could protect their reproductive organs from unwanted medical intrusions can vagina measures. >> scandal! we'll talk to the conservative critic leading that boycott in just a minute. william donohue, from the catholic league. >> [ inaudible ] >> i think -- i don't want to say anything about those remarks. >> interesting. it gets better than that too. and we have a conservative pundit who says that ann romney was a genius for marrying well that that's better than having a career, and this is how that pundit earns a living. >> oh hi. >> hey, how are you. >> we're just brushing our dogs. >> we're just kicking it. >> we aren't we. we'll do a segment on her too. it's go time. >>> well tonight we start with an interesting story of a successful boycott and an unsuccessful boycott. first let's start with the unsucc

. >> john, i would wonder if you would address the question addressed by jeffrey sachs, and that we continuallyrefer to the united states and aid that we give to foreign nations, but when you look at the private charities of the united states and what they provide, the churches, educational institutions, foundations -- and the kind of grants that are made to foreign nations, we are by far the most generous nation in the world. we comment on that? >> i think that you have answered your own question. it is not true what they say, and i would add that private individuals give, and all these people go to these countries and do missionary work. what right does my government have to forcibly take money from me and to have my government give aid money to other countries? i would say that ron paul is right. we should cut foreign aid to zero, and the hb given by private individuals who freely want to give it. americans are uniquely generous that way. it is sort of funny that churches tell people to tithe 10%, and americans are the most generous, but even in america, people don't give 10% of their income
