Einstein And The Bees

In terms of agriculture, the loss of bees would dramatically alter human food systems but would not likely lead to famine. The majority of human calories still come from cereal grains, which are wind-pollinated and are therefore unaffected by bee populations. Many fruits and vegetables, however, are insect-pollinated and could not be grown at such a large scale, or so cheaply, without bees. Blueberries and cherries, for example, rely on honeybees for up to 90 percent of their pollination. Although hand-pollination is a possibility for most fruit and vegetable crops, it is incredibly labor-intensive and expensive. Tiny robotic pollinator drones have been developed in Japan but remain prohibitively (使人望而卻步地) expensive for entire orchards (果園) or fields of time-sensitive flowers. Without bees, the availability and diversity of fresh produce would decline substantially, and human nutrition would likely suffer. Crops that would not be cost-effective to hand- or robot-pollinate would likely be lost or persist only with the dedication of human hobbyists.
