What ecosystem collapses when removing a single creature? Are you talking about pre-holoscene extinction ecosystems? Or are you talking about modern ecosystems (after most of the original biodiversity has already been obliterated, and “removing one species” is actually thousands down on the list of removals)?
But the second is talking about abuses against males. If anything, using two words “dismissed, and sacked” one in each paragraph, makes it even more confusing. Felt like it was saying women in senior positions protected women less (dismissed abusers) while protecting men more (sacking abusers). Just say sacked both times.
