Locust Swarms Destroying Crops Across Ethiopia

Swarms Of Locusts Spread Across Australia

Swarms of locusts are sweeping parts of Australia right now measuring about four miles long and 170 meters wide. Locusts feed mainly on vegetation and since this is the time for farmers to harvest their crops the government has about nine planes on standby to treat the swarms if they get any larger.
