“The world [needs] to produce 50-60% more food by 2050 … to feed its growing population. But crop yields … [are] projected to decline by between 3-12% as a result of global heating.” Quote from Dr Cary Fowler, who is known as the “father” of the Svalbard Global Seed Vault.
“We are in the midst of a global food crisis,” he said. “More than 700 million people were undernourished in 2022 compared to 613 million in 2019.”
…and that’s the way the trends are going.
