It's simply asking "what are the safeguards of capitalism that prevents a terrible person from doing terrible things with its seeming limitless ability to affect the Earth and its inhabitants?"
So far the answer has been: Western Democracy
"Is western democracy is enough to keep capitalism from doing terrible things to Earth and its inhabitants" is my question. The framing obviously alludes to the argument:
Western democracy is either complicit in allowing genocide and conflict across the middle east over the past three decades, or it has been too powerless and ineffective to prevent it. Maybe we should give the opposition to capitalism (any form of anti-capitalism) a try to maintain peace across this beautiful world we all inhabit and need to live.
