Re: their actions could make much difference
"People" does not appear before "they" and "their actions" so it would be difficult for the two phrases to refer back to them. Both refer to "Social campaigns". Whilst I agree that a campaign, as an inanimate object, can't actually physically take action, I wouldn't say that that means that "their actions" has to refer to the people taken the actions.
