my name is evan fraser and i work at the university of coffin ontario canada

情態副詞

mostly what i do is to try and understand one of the biggest issues

facing our world over the next fifty years

the first shows us how much food you could buy for one dollar

on a market in the african nation of zambia

the second shows us how much you could buy on the same market for one dollar

what happened in between was skyrocketing food prices

maybe even hundreds of millions into poverty

remember the revolutions that swept the middle east in two thousand eleven

many of the world's top agricultural experts believe that this is just a tip

unless we figure out new strategies to deal with global food security

we may be entering a new and dangerous fades of human history

there are a number of reasons for this alarm

the first reason is that in most years we produced only just enough food to

in six of the last eleven years we actually consumed slightly more food

and the buffer we take from one year to the next has been steadily

so our system already seems pretty fragile

it's when we look into the future that things grow very dire indeed

and are rich diets that take a lot more resources to produce than they used to

but producing this food is going to be hard

this is because the rising demand is coming precisely at the same time

shaking in these grim statistics is a four apart blueprint we need to follow

but since each of these strategies is extremely controversial

the first strategy include science and technology

a major scientific hurdle is to develop technologies that will help farmers

reach their potential in terms of the amount of food they produce

some scientists figure we could easily boost production by fifty percent

just fighter plane currently available technologies

this is especially important in regions like sub-saharan africa

where many farmers only produce about twenty percent of what they could

but it's not as if we can take the seeds equipment that seem to work on north

and simply give them away to african farmers

are totally different than in north america or europe

just using science and technology won't be enough however

and this is where the second strategy comes in

we must do a better job of distributing the food we've got

to develop a strategy we need to consider an uncomfortable truth about

and divided equally by all the people on the planet

about twenty seven hundred calories per person per day

and seventy five grams of protein per person per day

but because we feed a lot of our food animals

or true corn into ethanol or simply waste vast amounts

maybe twenty to fifty percent of the world's food is wasted

or because the people who need the food are too poor to afford it

so we need to establish waste of making sure that less food is wasted

and the food we do have is better distributed

one way of doing this is through ensuring that international aid

have better access to food stories that can be used as short term food aid

we need to make sure we keep the healthy population of farms and farmers around

this means we need to support local food systems which are important because they

stand as a buffer between individual consumers
