Climate change is affecting food supplies, cutting back heavily, or even some crops, according to a new United Nations report. Unpredictable storms, wildfires, droughts, floods, unpredictable food production, which will lead to reduced food production, mean fewer quantities of food available to humans, higher food prices, and many agricultural and by-products will not be available.
By 2100, the main grain crops of all kinds may be significantly reduced, with reductions of 20-45% of maize, 5-50% of wheat, 20-30% rice and 30-60% of soybeans. In addition, climate change will lead to an increase in pests and diseases.
Experts say the world’s population could reach 10 billion by 2050, and that 60 percent more food is needed to be eaten by all. The more vulnerable in the future are those in low-income countries, where agricultural prices have skyrocketed, while rich countries account for most of the world’s agricultural products, and low-income countries may not be able to feed many people.
The world food crisis, which erupted in 2007-2008, had a world food reserve of only 405 million tons, enough for 53 days. Food prices have soared and protests and unrest have broken out in many countries.
In addition, there is malnutrition, increased carbon dioxide levels in the atmosphere, increased photosynthesis of plants, plants grow faster, have fewer proteins entering the seeds, and plants use more protein to grow.
The protein-based influence of crop species decreased, and trace elements such as zinc and iron also declined, and the nutrients people can get from crops were reduced accordingly.
Research shows that by 2050, the global zinc deficiency population will reach 138 million, 148 million people or suffering from protein deficiency.
