According to estimates, there will be nine billion people on this planet by 2050. How are we going to feed them all?
And it's an important question. Scientists believe that with the world's population set to hit the nine billion mark, we'll need 50 per cent more food by mid-century than we do today.
Food is already a serious problem around the world: as of now, the World Food Programme says 870 million people go to bed hungry each night.
Meanwhile, rising energy prices and the effects of climate change are making it harder and more expensive to grow food than it used to be.
Different groups have offered solutions to the problem. Some believe that if we distributed food more efficiently - and ensured that organizations like the WFP had enough food to supply short term aid - we'd be able to feed everyone with what we've got now.
Advocates for science and technology, meanwhile, suggest that funding research centres is the key, since it will lead to the creation of more efficient seeds that consume fewer resources.
And others suggest that factory farming is the problem, and that in the future we'll have to rely on local food production to feed the world.
The purpose of the video, and an accompanying website called Feeding Nine Billion, is to explore these different viewpoints on solving the food crisis, and try and put them together to come up with a solution to the problem.
Here are the four areas Dr. Fraser sees as central to the solution: Science and Technology, Distribution, Local Food Systems, and Regulation.
As for how they're all going to work together, and how we can get involved in making them happen, that's where the website comes in.
Dr. Fraser and his team want people to raise awareness about the issue of food scarcity by sharing the video and visiting their site to vote on which food production solution they're most interested in hearing more about (at the moment, Local Farming has the most votes).
Over the next year, the team plans to release more videos and add more content to the site based on what subjects get the most votes from users. And if you want to get involved, there's a ten-point "Take Action" plan on the site. Check that out right here.
