The fear of lack of farmer to grow food has been exist for many decades, Industrial revolution, technological revolution, Internet, and now crypto. But it has been proven that we still eat until now, and there is still food circulating in the world, not to mention that tons of food is wasted everyday. The improvement in the agriculture industry and the advancement in technology in fact help farmers to produce foods more effectively, so even with less number of farmers the food is still enough. The problem is not in the amount of food, it is the uneven distribution. There are ton of food wasted in the rich country while there are some people in poor countries that can't eat regularly every day.
The introduction of genetically modified organisms (GMOs) in the agricultural sector has improved food production to a large extent. Farmers can now produce more with fewer resources because of these technological organisms. Technological advanced agricultural tools are also contributing to the increase in food production. A
report stated that the US wastes about $444 billion worth of food annually which is about 149 billion meals.
However, there has been some criticism of these GMOs from the health sector. Some health practitioners have claimed that these plants and animals have some negative health implications. These health personnel are encouraging people to consume natural or organic foods instead of inorganic agricultural produce.
Poor countries have fertile lands and enough manpower. But they lack technology and finance and some of them are plagued with wars and conflicts. The majority of farmers in developing nations rely on crude implements and most of them do not have access to finance to buy good seedlings, fertilizer, chemicals, etc.
