Human-centred design ignores sustainability, inequity and bias, so design has to move to humanity-centred design that covers the whole ecosystem and the long term.

These are important principles, but they ignore the problems of sustainability, inequity, and bias. In addition, the emphasis is usually on the immediate issues, not the long-term impact. In other words, they describe the way we did things in the past, not the issues in this book, and not the way we need to do things in the future.
