I think they're attainable if we want them to be attainable, and I hope that we do, because as my colleague said so eloquently in her presentation, this is a huge global tragedy that exists that 1.4 billion people live on less than $1 a day. For them, a luxury is a shack in a shantytown, or access to a toilet. And that's abysmal and abhorrent to me.
I think it's a lack of political will globally in terms of wanting to put our priorities in other places. Obviously, if we build that political will and we stand up and say this is unacceptable, then, if we can put a man on the moon, surely we can ensure that a child in Africa doesn't die for lack of drugs that cost pennies.
