line the amount of arable land is
line the amount of arable land is probably going to go down as the
probably going to go down as the
probably going to go down as the population grows we need to build houses
population grows we need to build houses
population grows we need to build houses for people to live in that will go on
for people to live in that will go on
for people to live in that will go on arable land climate change will probably
arable land climate change will probably
arable land climate change will probably result in the loss of farmland so in

fact if anything in the next 33 years
fact if anything in the next 33 years the amount of arable land on earth is
the amount of arable land on earth is
the amount of arable land on earth is going to go down that’s the land we grow
going to go down that’s the land we grow
going to go down that’s the land we grow our food on here’s what happens when you
our food on here’s what happens when you
our food on here’s what happens when you superimpose population growth on top of
superimpose population growth on top of
superimpose population growth on top of that population right this minute is 7.5
that population right this minute is 7.5
that population right this minute is 7.5 billion individuals on this saury planet
billion individuals on this saury planet
billion individuals on this saury planet the planet is going to be a lot sorrier
the planet is going to be a lot sorrier
the planet is going to be a lot sorrier by 2050 with conservatively 9.5 billion
by 2050 with conservatively 9.5 billion
by 2050 with conservatively 9.5 billion so we’re going to add 2 billion some
so we’re going to add 2 billion some
so we’re going to add 2 billion some people say we’re going to add 3 billion
people say we’re going to add 3 billion
people say we’re going to add 3 billion more people how do we solve that
more people how do we solve that
more people how do we solve that difference how do we feed 3 billion more
difference how do we feed 3 billion more
difference how do we feed 3 billion more people with the limited farmland

about today Golden Rice is an idea that
about today Golden Rice is an idea that came about in the early 1980s before we
came about in the early 1980s before we
came about in the early 1980s before we even had the techniques for doing the
even had the techniques for doing the
even had the techniques for doing the gene transformations that I’m talking
gene transformations that I’m talking
gene transformations that I’m talking about a lot of people in Southeast Asia
about a lot of people in Southeast Asia
about a lot of people in Southeast Asia millions of people in Southeast Asia and
millions of people in Southeast Asia and
millions of people in Southeast Asia and Africa have rice as their sole or their
Africa have rice as their sole or their
Africa have rice as their sole or their main food source the problem with rice
main food source the problem with rice
main food source the problem with rice is that it itself is vitamin A deficient
is that it itself is vitamin A deficient
is that it itself is vitamin A deficient that means that rice doesn’t make enough
that means that rice doesn’t make enough
that means that rice doesn’t make enough vitamin A and people that eat rice

people that came up with the Golden Rice
people that came up with the Golden Rice idea said let’s put genes into rice that
idea said let’s put genes into rice that
idea said let’s put genes into rice that means that the rice plant itself is more

mark 2 produces 23 times the amount of
mark 2 produces 23 times the amount of vitamin A of wild type rice so this is a
vitamin A of wild type rice so this is a
vitamin A of wild type rice so this is a success story this technology will
