Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

Vast swarms of locusts sweep across Australia

After years of drought, Australia’s harvest faces a different threat

As farmers prepare to harvest their crops, large swarms of locusts plague Australia

Vast swarms, some measuring up to seven km long, have been observed at Condobolin, Gundagai, Narrandera and Wagga Wagga.

The NSW State Government has reportedly dispatched pesticides to farmers to spray about 100,000 hectares of locust bands and has a fleet of nine crop spraying aircraft on standby-the only way they know how to fight the locusts!

Locust is the swarming phase of short-horned grasshoppers of the family Acrididae, some of which reached 15 cm in length. These species can breed rapidly under suitable conditions and subsequently become gregarious and migratory. They form bands as nymphs and swarms as adults — both of which can travel great distances, rapidly stripping fields and greatly damaging crops. [Wikipedia]
