For species we are interested in - we are that guarantee. For others - why should anyone care? Humans are priority. As for infrastructure: you probably aware we are demolishing and rebuilding it constantly anyway. Compare even modern roads with roads at 1900. As for culture - people change they culture constantly anyway. Any emigrant? Voluntary changed culture? Moved from a city to suburb? Change of culture. Gone to get college education? Change if culture. And cultures themselves are not something remotely approaching anything "constant".
