With most global temperature estimates pointing toward a troubling increase of 2 to 4.9 degrees Celsius by the end of the century (median forecast at 3.2 degrees), experts have predicted that warmer temperatures will cause insect populations and metabolism to rise. Many of the world’s staple food sources are expected to be at risk to these crop-eating pests, with wheat harvests at the highest risk of plummeting by 46%, maize harvests at 31% and rice harvests at the lowest of 19%. This is alarming as the aforementioned food sources make up 42% of global calorie intake worldwide. Farmers and agricultural producers worldwide have been urged to respond with new pesticide methods, revised planting cycles and even genetically modified crops to counter the impending crisis.
