Around the globe there are many places where there is not enough food for everyone, I will state what is the main causes in my point of view and give the solutions, and lastly I will do a conclusion to summarize it all up.
I think the primary cause of it is, that most food sources are not being used efficiently. I strongly believe that there are a lot of more valuable methods of extracting food that are not being used to it is full potential. Which causes a global shortage. For example instead of planting 1 acre of corn which feeds about 40 people for a week. We can plant wheat which will feed double the amount in that same period. Another possible cause is, there is a lot of food that are being wasted around the world. which if we can benefit from it will help many people.
For the first problem I suggest that there should be polices around the world which maintains a constant rate of efficient farm land planted to keep up of the population of the world. For the second problem, I think we must do educational lectures around the globe to help people understand the blessing of food.
To conclude, while there might be a lot of reasons to why there is a food shortage globally.I believe that we can do much better with current problems if we approach them correctly.
