I think 100 million liberals would be great in antartica

? · Answer

At 100 million the Australian environment would collapse within decades due to an exhausted water supply.

Edit - The basin is already showing signs of declines due to over use. The water is not being replaced as quickly as it is being taken out. Many bore holes are no longer viable due to water levels dropping and lack of pressure.

Accelerating the population would also accelerate the decline.
