The TED talk states that the Ethnosphere is at risk because there is a belief that the world must be a cohesive whole that should speak the same languages and believe in the same things. Realistically speaking not only is this impossible, but it is to put it simply a huge misconception. I feel like the world will not be a better place if we all spoke the same language, practiced the same religion, or dressed in the same way because that would mean abolishing cultures that have been around for thousands and thousand of years (besides how would anyone even decide which culture would be the one to keep, thats just asking for trouble).
In the sense of cultural diversity acceptance, I think Australia is a model country that all should follow. The governments involvement in policy making and funding has helped create a country that is accepting towards all. This being said, I believe that government officials should be actively involved in the making of legislation to create a country and a world that is more accepting and culturally aware. Involving the government in topics such as these can have its risks. There are many people who are against changed and opposed to opening their doors to those who have a different way of life, so involving the government can cause great political controversy. Like the TED talk said, politicians will never accomplish anything, and I can't help to believe that it is because addressing the issue of citizenship, and culture will put their reputations at risk. But what is more important, a person's political position and power, or a region's uniqueness and cultural identity? We simply can not sit idly by as entire cultures begin to disappear due to the lack of awareness and concern. Yes involving the government and politicians can have its risks, but to me the larger risk is losing the characteristic that makes earth so unique, which is the abundance of human life and the great cultural differences each and everyone of us have. We can not allow cultural diversity to continue to suffer just as biodiversity is suffering.
