Let's do the math:
clean water = ice cream - $2bn = $9bn health care = pet food - $4bn = $13bn education = cosmetics - $2bn = $6bn
thus clean water + health care + education = $28bn
then we read:
> $40 BILLION A YEAR -- It is estimated that the additional cost of
>achieving and maintaining universal access to basic education and
>health care for all, reproductive health care for all women,
>adequate food and clean water and safe sewers for all is roughly $40
>billion a year -- or less than 4 percent of the combined wealth of the
>225 richest people in the world.
>
ergo: $28bn = $40bn
astonishing, indeed.
