I'm really interested in making people understand

0:00:09.018,0:00:12.097
about sanitation issues in the developing world.

0:00:12.097,0:00:14.183
And I think if I were to give a TED Talk,

0:00:14.183,0:00:15.470
I would focus on that,

0:00:15.470,0:00:17.430
on the 2.5 billion people

0:00:17.430,0:00:20.216
who don't have access to sanitation

0:00:20.216,0:00:23.797
and try to show solutions

0:00:23.797,0:00:25.684
and also how we should change

0:00:25.684,0:00:27.154
how we think about this problem

0:00:27.154,0:00:29.613
because it's really a big, big problem in the world.
