How will we feed a growing population ?
the world 's population is expected to exceed 8 billion by 2025.
Much of this increase will occur in the cities of developing countries
Unfortunately , food production , instead of increasing , has decreased over the last ten years.
As it is , some 40000 people die from hunger - related causes every day .
The only way to increase food production seems to be through technology ,
since land and water are getting scarce.
