Johhny Electriglide "The idea of borders to territories has been around since pre-history. Violation led to wars when it was a large amount. Small groups of visitors/travelers/trading people were allowed. The USA is invaded by 30 million, who are taking jobs Americans want, and taking benefits they never paid in for, and stated purposeful anti-environmental over-breeding with the goal of conquest the easy way (like the islamics in Europe have stated).
I joined the service to fight communism's spread for a small country that was too weak to fight the loss of freedom on its own. Communism is an enemy of freedom loving people, so is islam. Over-breeders are the enemy of the Earth.
The idea of one world all kumbaya is defeated by peoples who are in the above categories. It is also defeated by the fact that there is just too much variation in humans, especially in intelligence, and also in cultures and language.
I'm not sure what you mean by "pre-history". If it is part of our story, then it is history. Borders began at some point in our history.
The U.S. began as an idea .... an idea that hundreds of thousands held as true. Now, hundreds of millions hold the idea as true. We have separated ourselves into nations, which are ideas and therefore ideologies. We have also separated ourselves into religions, most of them so dominant that they have become known as "world religions". Nations and religions have assumed such footholds in our belief system that we fight over them because "groups" as nation or religion become written in stone .... as if they are real. But they are not. They are a product of thought.
The world is a populated place and the people of the world spill into the US and Canada and Europe. It is inevitable. There will be more of it. You can pretty much count on it. They are "over-breeding" because of the influences of their cultures which have, for them, a lot to do with their own survival-welfare as well as religious beliefs. Yet first world countries do their part to keep them in poverty. Multinationals have long since moved into their countries to set up mines, banana plantations (hello Dole!), and factories ... and military centers. The list of takeovers is endless and multi-faceted. It is oppression of the first degree and it is focussed on making money and answering to share-holders with third world peoples and their environments as their fodder. Choas is bound to ensue when the basic needs of people - and in fact, entire countries, is at risk. Food and shelter and freedom from violence is what all people from all regions of the world require for basic security.
There is overpopulation for sure, particularly in light of the systems: economic and national, that we currently have in place. We think our problems are problems of economics or environment or ..... ? But really our crisis is a crisis of consciousness. if we don't get it, we continue to create divisiion and the division is itself, delusion. Monsanto is a multinational company and must compete with local farmers in order to do well.
Monsanto, like all corporations, is a government in itself with the usual goal of making profit and it will not solve the problem of people going hungry because it's main concern is more about profit than it is about altruism. Only local communities who can look after their own comunities will do it. That goes for the US as well. And BTW, we don't really want to buy the world a Coke. Only fascists want to buy the world a Coke!
When such a small percentage of the world's population is creating so much environmental destruction, both locally and abroad, you have to wonder about the systems in place ..... don't you?
It is far too overwhelming a conundrum to imagine that the vast problems can be solved on an international or mass level. They cannot be solved as per "other" people. There have been many revolutions and none have created any real change in human consciousness. The only way is through the Self. But for that to be real, one need first recognize that self is other. Not as opinion or belief or perspective, but as simple fact. Ever single one of us needs food, shelter and basic security and none of us experiences life in a vacuum. One person's experience of being human is akin to the next persons'.
We made up the ideas seemingly forever entrenched as economic, national and religious, but they are still just ideas. All people require freedom and so are freedom loving and that is why they are moving in droves to North America and Europe. The over-breeders, as you csll them, are a result of vast inequalities in the way we do business. We are endowed with the ability to behave more intelligently as a very small planet in a vast universe. How far above our planet does one need to travel in order to seee a planet without borders? It was us who created those borders. Our crisis is a crisis in consciousness.
Let there be differences in language and cultures and intelligence. Variation is what the world and even universe is made of and humans are one part of that variation. There has never been anything but variation. I hope you would not like to put an end to that as there have been people before you who have had the same idea and have tried to eliminate those differences ..... and have, of course, failed but not without much destruction and unwarranted suffering.
We have huge problems amongst us and they are strengthend by the ideas (ideologies) of nationalism and religion. There is absolutely no way for one group of people to be secure at the expense of another. Any action towards such an end only creates greater insecurity for everyone.
