If the rovers haven't been properly sterilized already, will this throw doubt upon any possible future discovery of Mars-based microbes living in or near the water? Wouldn't detractors be able to claim that they are microbes that somehow survived from Earth?

I always wondered how any of you celebrated types are able to keep a clean cell phone. Now I know.

A few questions:

1) What would you say is the health impact on children in the areas you have focused on? For example the areas that have had significant lead exposure or exposure to burning e-waste. I'm mainly wondering about the lasting economic impact of permanent health damage to the next generation of adults, and to what degree that is expected to impact developing economies.

2) How possible is it to change things at the systemic level, so that instead of finding better ways to recycle toxic waste that is dumped in a country, there is just no more toxic waste dumped there? Is the main problem with the poverty in the affected areas or the legal system of the areas doing the affecting in your view?

3) How do you battle entrenched attitudes and behaviors when it comes to further polluting already polluted areas?
