After cycling the entire perimeter of Australia, I attest to the reality that 90 percent of your country remains a massive desert with limited arable land and water. Having read the report that Victoria's population is now set to reach 10 million by 2051, I must alert you to the consequences and futility of endless immigration. As a six continent world "push-bike" traveler, I witnessed the end result of global birth rates in India, China, Mexico and Africa.
First, let's examine what transpired with the human race in the last century. What about the sources of immigration? What happened after Earth Day in 1970? What about the specter of overpopulation? Second, where do you think water, food, energy and resources will come from as you explode your population beyond sustainability?
My long time colleague, the late Dr. Albert Bartlett said, "Unlimited population growth cannot be sustained; you cannot sustain growth in the rates of consumption of resources. No species can overrun the carrying capacity of a finite land mass. This Law cannot be repealed and is not negotiable. Al Bartlett, University of Colorado, USA.
His quote stands as the benchmark for humanity's greatest predicament in the 21st century: human overpopulation. In 1970, the human race stood at 3.5 billion people. Because of Earth Day, Australian women intelligently chose two children families as have America, Canada and Europe. Unfortunately, the developing world doubled from 3.5 billion to 7.3 billion and is headed for 10.1 billion by 2050—a scant 34 years from now. Humans add another 1 billion of themselves every 12 years according to the United Nations' population projections.
Africa, at 1.1 billion people in 2016, expects to reach 2.0 billion by 2050 and 4.0 billion by the end of the century. India, at 1.2 billion, adds 16 million annually, net gain, and will surpass China at 1.55 billion by 2050. Humans add 80 million of themselves, net gain,every year.
In other words, no matter how much Australia or other Western countries attempt to save the rest of humanity with mass immigration, you will not save overpopulated countries, but you will destroy your viability as a civilization. Even if you import 10 million immigrants a year, 80 million more are added . It's a Faustian Bargain with a final result of Hobson's Choice. Not pretty! All the while, we degrade Earth's ability to function as to carbon footprint, water footprint, diminishing arable land, accelerating extinction rates and acidified oceans of our biosphere.
Along the way, you force upon yourselves an irreversible quality of life and standard of living degradation. Once the "population bomb" lands on Australia, you create future consequences with unsolvable problems. All the while, you degrade your environment and Earth's viability as a functioning biosphere. Additionally, you force upon yourselves a total sociological change in your population that will end in displacement of Australian culture, language and values. Notice the extraordinary disruption, violence and disorder taking place in Europe and America today via mass immigration.
In my 45 years of world "push-bike" travel, I witnessed the extensive misery, human suffering and entrenched poverty of societies that have refused to practice birth control. I've watched refugees cascade into first world countries for a better life. Unfortunately, they recreate the same consequences from which they fled in their new host countries—human overload, quality of life degradation and loss of standard of living for host country's citizens.
If Australia and all Western countries continue mass immigration resulting in overpopulation of their own countries, nobody wins and everyone loses.
"Most Western elites continue urging the wealthy West not to stem the migrant tide [that adds 80 million net gain annually to the planet], but to absorb our global brothers and sisters until their horrid ordeal has been endured and shared by all—ten billion humans packed onto an ecologically devastated planet." — Dr. Otis Graham, "Unguarded Gates".
You must ask yourselves these questions: where is our Australian civilization headed? Will we overpopulate ourselves into third world misery via endless immigration or will we change course? What do we bequeath to our children? What kind of culture will they inherit? Who will stand up for Australia's citizens and their interests?
"If we don't halt population growth with justice and compassion, it will be done for us by nature, brutally and without pity – and will leave a ravaged world." ~Nobel Laureate Dr. Henry W. Kendall Your choices could lead the world to a smarter, more intelligent and sustainable future. If you maintain endless immigration, you will become exactly like India, China and Bangladesh.
At some point, you will run out of options or answers, or both.
