Urbanisation threat to global food crops as bees struggle to source food and nests

Increasing urbanisation is making it harder than ever for wild bees to find food and nests, potentially threatening the 75% of global food crops which rely on pollination.

Researchers at York University in Toronto found that the encroachment into bees’ natural territory from urbanisation means they will also find it increasingly difficult to mate in the future.
