Earth can feed only 3.4 billion people. What do the rest do?

Current food system mayfeed only 3.4 billion people, reports portal newscientist.com. In the event that a person does not go beyond planetary boundaries, most of the world's population is threatened by a lack of food. At the same time, experts offer a less radical way to solve the global problem by reorganizing the modern agricultural system, which will allow the planet to feed more than 10 billion people.

A modern global agricultural system can feed just 3.4 billion people

Mankind lacks food

Food production through environmentalThe environment can no longer move in this direction, says Dieter Gerten of the Potsdam Institute for Climate Impact Research in Germany. It is known that in 2009, experts identified nine planetary boundaries that humanity should not exceed if it wants to maintain its livelihoods on the planet without a sharp reduction in its population. According to researchers, for this, humanity must adhere to a certain framework that is directly related to agriculture. So, we must not take too much fresh water from rivers and lakes, we must limit our use of nitrogen and nitrogen compounds, as well as not cut down a large amount of forest and maintain the general biodiversity of the planet.

Having studied the modern food offer,the team concluded that half of modern industries violates all these natural requirements, jeopardizing the livelihoods of our planet. Such an unpleasant situation can be solved by reprofiling modern farms in areas where more than 5% of species are currently threatened with extinction. In addition, researchers offer a similar solution for agricultural land, where more than 85% of tropical forests are cut down, as well as in places with active water intake for irrigation and places with high surface water levels.

Genome editing technology will help humanity solve the food crisis

According to experts, the introduction of suchmeasures could mean a significant restriction on fertilizer use in parts of China, Central Europe, as well as parts of Africa and the United States. The introduction of a package of such measures can help ensure sustainable food production for 7.8 billion people, which roughly corresponds to the current population of the planet. In addition, reducing the amount of meat consumed can help increase this figure to 10.2 billion people, slightly more than the projected number of the world's population by 2050.

The ambitious plan of scientists has only one “but.” So, the team of researchers suggests that the effects of global warming may affect the positive changes in the agriculture of the planet. In this case, humanity will have to rely only on genome editing technology and the use of electricity from solar panels in order to grow food products of the future.
