The populations of many pollinator insects ‚?? bees, wasps, and
butterflies ‚?? are in decline. Many crops rely on pollinators which
raises concerns about the future of our food.
Three-quarters of our crops depend on pollinators to some extent, but
only one-third of global crop/production/does. This is because many of
our largest producing crops (staples such as cereals) are not dependent
on them at all.
Very few crops are completely dependent. Most would see a decline in
yields if pollinator insects disappeared, but would not collapse
completely. Taking all this in account, studies suggest crop production
would decline by around 5% in higher income countries, and 8% at
low-to-middle incomes if pollinator insects vanished.
