You would think a site called "Nature" would provide a less human-centric point of view: "The elimination of Anopheles would be very significant for mankind."

"A stronger argument for keeping mosquitoes might be found if they provide 'ecosystem services' — the benefits that humans derive from nature."

Just because we (might) have the means to eradicate them doesn't necessarily mean we should.

Though the article ends with a quote about how the niche could be filled by something better or worse, most of the article claims that the other organisms that would fill the niche would make things better. There is a pretty big possibility that things could become a lot worse (say, instead of spreading malaria, the replacements spread ebola).
