I think you're being a little selective in trying to show your point. Human-driven climate change is the biggest driver of ecological damage. Even the article you link to is based on a report that climate change is the biggest driver of desertification worldwide.

I agree with you that land management can mitigate desertification, the same way hunting invasive species can help protect native biodiversity.

This doesn't mean it's wrong to focus on climate change, and by extension, carbon emissions. If anything, they demonstrate that we should focus on climate change. It's like scaling an internet technology company: we want to build something small that has a massive impact.

Reducing carbon emissions will by far have a greater impact than trying to eradicate sea urchins from the pacific northwest. It is just as feasible as better land management. And for things like coral reef bleaching, which I'm personally very interested in, it's unclear if there's any other solution.
