A biological conservation review claims the number of insects in the world is declining at a rapid rate, with extinction expected for 40% of the global insect population within the next decade.
The review, entitled "Worldwide decline of the entomofauna: A review of its drivers" put together 73 different scientific studies on insect decline from around the world.
Entomologist Silvio Melesi tells SBS what severe consequences an upcoming insect extinction could have.
