I think when you have to look at this problem really you need to look at this. There are natural domain problem there are societal domain problem these have been studied forever but they also happen in a politically real world so one in water diplomacy what we are arguing for last several years that look you need to understand the natural problem you need to understand the natural problem you need to also understand that this is happening in a politically real world. So how do I combine this scientific knowledge and social knowledge in a politically real world where things will have some way to at least have some traction? I don't have to discuss this idea of really look. I only need 0.14% of GDP still people do not have access to water 768 million people do not have access to water these are all known problems go to any water literature right now any water crisis you'll see this status is given everywhere so come nothing is being done then those are the type of questions we want to raise and hopefully you guys will have some clue really when you are in your organization to have some impact. So the reason I think what we argue that is happening that there are differences in political boundaries, knowledge, know-how, management, these are all basically happening at multiple scales. And these choices are particularly problematic because they cross boundaries, they have uncertainty
