Does anyone else think that the white race is ending? Caused by low birth rates etc?

This is not only happening to white people, I am seeing it in minorities too. More minorities are getting married late, having children later and an increasing number of women are working. I know families where the last generation had like 6-7 kids, this generation has 3-4...it's happening everywhere. Also people who are commenting on mixed race, if mixed race people keep having kids somewhere down the line white features start to resurface.
