Yes it is possible because nowadays technology is improving that helps us in our lifestyle. Technology can also be a way to help more fruits and vegetables to grow in local farms because in statusquo, our problem is just unhealthy farms that lack the soil because of changes in climate.
Yes, it is possible to avoid a global food crisis. It is important for those in professional agriculture to participate in research and development to efficientize food processes. They should adapt and implement advanced methods and strong strains. Small pouches of nutritional "goop" have also been developed, and are relatively inexpensive and easy to transport.
While I still think genetically modified foods need to be tested for safety, I would say there is a high chance that they are safe for consumption. With more efficient crops I do believe a global food crisis is avoidable. We have plenty of resources to grow and harvest more food, we just have to utilize those resources.
Yes, the global food crisis is avoidable, if we only serve people in the United States a healthy amount of food, and do not allow so much food to be wasted like it is. If we start shipping a lot to the places that need food we can help alot.
As much as most people want to avoid a global food crisis, it is not avoidable. There is just way too much logistical and financial obstacles to overcome a global food crisis. There are a lot of nations on Earth that just cannot fend for themselves for various reasons. And the ability and resources to help them is just not available.
There is a finite amount of farm land that can be used to grow crops and other things in order to feed the world's growing population. It is not unreasonable to assume that this will create a global food crisis. I think the only way around it is finding alternative forms of food.
