swan song for the white 'race'

Are whites losing thier dominance?
Lately I noticed many areas were whites seem to lose the upperhand:
south africa, in the us the white is "old and gone", France's national football team has usually 7-8 african players (born in france). Youtube videos from uk full with muslims, brussels the same, netherlands germany and some other countries in europe all the same. How many whites are in NZ and Australia and how many asians wait to go there? How long will they still wait? The same thing for Siberia.
Now apart from the bad things, whites have conquered and mapped this earth for all human beings. Some crazy dutch went to new zealand with thier ships! Some english dudes ruled India and maybe even China.
Almost all major late discoveries are made by white people. The current global culture is based on white culture.
But is this 600-700 years of white "supremacy" coming to an end by changing demographics and literraly (peacefull)invasions?
