ELI5: If Amber, containing preserved insects, lasts for tens of millions of years, why aren't we up to our necks in the stuff?

I don't think you appreciate how large the area of land is on the earth relative to the number of trees that produce amber (and the amount a tree could produce). 

If every person on earth stood shoulder to shoulder they would fit in the space of a city like London, Mexico City or the area of San Francisco + Bay Area. That is the ENTIRE human population in the world today.
