The politics of a Science editor

Reviewing a new movie for Science, Sacha Vignieri, who is an associate editor of the journal, writes:

All people deserve an equal quality of life, but the unfortunate truth is that Earth cannot sustain a developed-country level of consumption for billions of people. As pointed out in the film, it would take all the resources of 10 Earths to support the current global human population at the consumption level of the United States.

There are three unsupported statements in this text:
1. All people deserve an equal quality of life.
2. Earth cannot sustain a developed-country level of consumption for billions of people.
3. It would take all the resources of 10 Earths to support the current global human population at the consumption level of the United States.
