Belly, like Foxy et al, your suggestion is a great one, but unfortunately, even if we could convince all nations to live in harmony, which is a big ask but not completely impossible, there is one obstacle that is impossible and therefore will render the whole idea moot.
And that major impediment, is, ISLAM! TA DAH!
Unless there is a way of rewiring Muslims to be more humane and inclusive and/or tolerant of other people of different religions.
The other way might be to convince the rest of the world that religion is a construct and it is not of spiritual substance, but originally by humans of questionable origins and agenda, and promoted by those with a lack of self esteem/worth

Gentlemen,

I've said this before in past discussions,
and I'll repeat it here again very few people
would deny that the planet has a finite amount
of resources or that it can tolerate only a
limited amount of pollution. If world population
continues to grow rapidly, if industrialisation
spreads around the world, and if pollution and
resource depletion continues at an increasing
rate - and all these things are happening - where
is human society headed?

The most optimistic answer to these questions
would be that, one way or another, sweeping
social changes await us all.

We also now have the risk of nuclear warfare on
the horizon. Whether we choose to destroy our
civilisation or save it is a collective decision
- and hopefully one that may well be made in
our lifetimes.

If more and more nuclear weapons are built
and more sophisticated means of delivering them
are devised and if more and more nations get control
of these vile devices then we surely risk our own
destruction.

If ways are found to reverse this process then we
can divert unprecedented energy and resources to
the real problems that face us, including poverty,
disease, overpopulation, injustice, oppression,
and the devastation of our natural environment.

We can only hope that our ultimate choice will be
to enhance the life on this bright and lovely
planet on which billions of us share our adventure.

Some people seem to think Australia is in trouble.
However why pick on Chinese. All my life Chinese have always been polite and helpful.

JF Aus,

The Chinese have been more than just polite
and helpful. They have raised the bar in
many schools and professions. We can learn
so much from them - especially how they
treat their family members and the elderly.

At the back of my mind, bet it is the same for others, the thought this chaotic world must change, lives
That one day, like it or not, some huge power,will take over and run the whole planet
Mentioning any race [Chinese here]just enforces the truth, we divide ourselves
Yes bring about changes in the way some seem to divide, question why integration and multicultures can not exist together
But unite is far easier than dividing ourselves

Dear Foxy,

Your description of the Chinese is very simplistic.

To explain the way traditional Chinese behave would require an extensive explanation in the anthropology, sociology and history of Chinese culture and society that would take one back two and half millenia to the teaching of Confucius.

The Chinese of the current diaspora, especially to Australia in their millions, are looking for a first world lifestyle and unfortunately for Australia that means an increasingly adverse footprint on our delicate environment. The LNP governments have been bringing in cashed up Chinese to keep the Australian economy afloat, which will mean an increasingly large intake of them to maintain an economic growth that our environment cannot in fact sustain.
