This is CBS Eye in the World. I'm John Batchewa, Bjorn Lomburg of the Hoover Institution,

as well as the Copenhagen consensus, his organization, commenting on the ambition of

the year 2000. A lot of history since then. We're in the third decade of the 21st century

and it's not clear where we're going. And the year 2015, when the nations came together

for goals to do with net zero, with climate change, with concerns about the deterioration

of the Earth's sustainability. However, at the same time, the United Nations made a much

longer list. The simple way was to say, laundry list, but that's inappropriate here. It's

a list of political thinking in 2015. Here we are halfway to the target 2015 to 2030.

And very little of this has been achieved. And you could say, well, listen, we're at a

war in Europe. And the global south is evidencing mass migration that comes up against the

conflicts with the global north. So why do you hold us accountable? Well, the fact is,

these ambitions are worthwhile. So Björn has identified it in his national post piece.

One goal that after reading about it seems immediately achievable. In fact, I'm amazed

that it hasn't happened yet. Björn, how do we end tuberculosis?

Well, it's actually very, very simple because we've already done it in the rest of the

world. Remember tuberculosis was probably the leading killer in the 1800s. We estimate

one fourth of everyone who died in the 1800s died from tuberculosis over the last 200

years, about a billion people have died from tuberculosis. A lot of the people you think

about from the 18 and early 1900s died from tuberculosis. Yet we fixed it because it's

a bacteria. You just give people drugs, simple drugs, and then it disappears. Now, it's

actually not quite as simple because you need to take it for four or six months. And

that's one of the troubles that is hard to get people to keep taking their medication.
