Food for 9 Billion: a global issue.

There are many complex aspects relating to this issue. To name just a few:
Global warming causing sea level changes threatens many of the major food production areas for many nations.
Increasing temperatures changes ecology and sustainability of food production areas.
The availability of freshwater is under threat. This also limits food production
Ocean acidification threatens edible marine foods including shellfish which many nations rely upon.
