Bees in South Korea are dying from extreme heat, but providing a spoonful of sugar water can help them survive [1].
This phenomenon threatens global food security because bees are essential for the pollination of the majority of human food crops. If bees disappear, 70% [1] of the human food supply would be at risk.
Reporting from YTN News highlights that the furry-coated bumblebee is particularly vulnerable during the current heatwave, which has persisted for several days [1]. These bees evolved with thick fur to withstand the cold of high-altitude climates. However, in extreme temperatures, that same insulation becomes a lethal heat trap [3].
Beyond the immediate loss of insect life, the decline of these pollinators has direct implications for agriculture. More than 70% [2] of major fruit and vegetable crops require bees to move pollen before they can produce fruit, a reporter for YTN News said.
Experts suggest that a simple intervention can save exhausted bees. When a bee is found immobilized by the heat, sugar water provides the necessary energy to help the insect recover and return to its colony [1].
"If bees disappear, 70% of human food will be threatened; bees are an absolute necessity for the Earth's ecosystem and our survival," a YTN News anchor said [1].

The vulnerability of bumblebees to heatwaves underscores a growing mismatch between evolutionary adaptations and the rapid onset of extreme weather. As species evolved for specific climates struggle to survive sudden temperature spikes, the stability of agricultural pollination services becomes increasingly fragile, potentially requiring human intervention to prevent large-scale crop failures.
