Changes in atmospheric composition and consequent global warming. Rich countries with high population densities have low rates of infant mortality.
I arrived in Australia 48 years ago this month. I arrived by boat for 10 quid. On landing I was surprised to find so few people. And apart from Australians there were quite a lot of Greeks and Italians. I was also surprised to find these immigrants were held in contempt in some quarters.
And I thought those countries had helped invent civilisation. There was also one Sikh and he became a friend.
The decisions being taken now about our population are literally determining what Australia will look like in So we should be making informed choices about our future. Rudd was Prime Minister at the time, and his off-hand comment created a storm.
The fundamental reason is that most of us live in or around our major cities. We accurately perceive that our quality of life has steadily declined as urban populations have grown. Successive state of the environment reports show that all the important environmental indicators are getting worse as a direct result of the increasing demands of our growing population.
In fact population growth is a serious environmental threat on the fringes of our cities as well as driving increasing greenhouse gas production. The water has been muddied by widespread misconceptions.
So I set out to identify some facts that could inform the debate. Each year aboutAustralians die and aboutbabies are born, so the population would grow by abouta year or about a day if there were no migration.
The confusion arises from the decline in the birth rate since reliable contraception became available. Where Australian women often had four of five children 50 years ago, the average number of children per adult woman is now about 1.
The birth rate has increased since the baby bonus was introduced, but there is a dispute about whether the financial incentives are the main cause. It was still a wasteful solution to a non-problem. The so called natural increase — births minus deaths — has never been less thana year in the last 50 years.
Of course we do also bring in migrants. Each year some people leave Australia and others arrive. The significant figure is the net migration, the difference between numbers arriving and leaving.
This has varied from year to year with political decisions between about 20, andThen the Howard government dramatically increased inward migration to well overA significant cause was the scam of education schemes that were really back-door visa programs, with dodgy private providers and some respectable institutions recruiting students with the implied promise of a short-cut to residency or even citizenship.
The current government has clamped down on those arrangements but the annual net migration is still abouta year. The balance of our immigration has also changed, historically by far the largest group of migrants were from the UK and Ireland but last year for the first time more migrants were of Chinese background than British.
Overall more migrants now come from the Asian region and Africa than from Europe and North America, so migrants are more visible on the streets, on public transport and in our institutions. Adding together the birth rate and migration, the Australian population is now growing by abouta year or another million every two and a half years.
While Kevin Rudd approved the calculation that our population could grow to 36 million byon current trends it could be over 40 million.
So we are right to be asking whether that sort of growth is manageable.Aug 23, · I have to do a project for school about the pros and cons of population growth.
Focused on Australia's population growth (cause thats where I live and just fyi it's supposed to increase rapidly over the next few years) but dosen't have to be just for Aus, just whatever, thanks in advance:DStatus: Resolved.
the impact of population growth, including migration, on Australia’s productivity growth. Productivity growth is a major driver of improvements in real per capita.
- With population growth comes challenges and difficulties. - People will be forced to come up with new ideas and ways of doing things. - Diseases, food shortages and pollution (all disadvantages) are problems that we will be forced to solve. Benefits and Advantages of an Increasing Population of a Country!
The consequences of a growth in a country’s population depend on its cause, size of population relative to optimum population and the rate of population growth.
i. If the population is above the optimum size, the country will be. In fact population growth is a serious environmental threat on the fringes of our cities as well as driving increasing greenhouse gas production.
The water has been muddied by widespread. Australia has a high population growth rate compared with other high-income nations, mainly because of its high level of immigration. Although birth rates are below replacement level, there is also a natural increase in population levels.
