Hi, this is Emily from MinuteEarth,
in a special collaboration with Bill and Melinda Gates. Recently,
we got the chance to ask Bill atough question: do countries have to become
wealthy before they can afford to build agood healthcare system?
Here’s what he said: Well,
if you think about healthcare,
the trend over time globally has been a very positive
Average life expectancy has gone from 36 years to now over 70 years. Now,
part of that has been that the world has gotten a lot richer,
and there is a very
strong correlation between how wealthy a country is
and how well it does on almost any health measure,
whether that’s childhood mortalityor average life span.
But what ’ s amazing, if you dig into it,
is there are countries that have done particularly
well – Costa Rica,
斯里兰卡 越南都是模范 还有卢旺达和埃塞俄比亚
Sri Lanka, Vietnam has been exemplar, Rwanda, and Ethiopia.
That is, at a low level of wealth,
by organizing something like a primary healthcare system,
they ’ ve gotten vaccines out,
they ’ ve gotten antibiotics out, they ’ ve helped with safe delivery,
they ’ ve made sure the sanitation
in their country is very well handled.
And so it ’ s not destiny that you have to wait
until you ’ re wealthy, until you have
As you get beyond the level of primary health care,
and you ’ re starting to deal with chronic disease,
like heart disease and cancer,
then building in a hospital system and an insurance system,
that becomes very very important.
And so we can see some countries that,
as they move to middle income, are doing that
We do need innovation because the cost of healthcare has been going up,
and so innovations
that can bring those costs down and make
even the most advanced care achievable around the world,
we need to keep investing in that.
Research and innovation in the space has been,
and will continue to be, what allows us to
Thanks for answering our question, Bill!
We were really excited to partner with Bill and Melinda Gates
on this video, and to help
them get the word out about their Annual Letter,
in which they share some pretty good reasons
to be optimistic about where humanity is headed.
Like the fact that, worldwide,
the rates of both childhood mortality and extreme poverty
are half what they once were.
And the fact that people all
over the world are continuing to work on solving our biggest challenges,
so life will keep on getting better.
That makes us here at MinuteEarth optimistic,too.
