>What are the benefits of focusing on biodiversity preservation?

They're not always aligned. There's many more issues that come out of low biodiveristy than just those affected by climate change. One important one that's unrelated would be high biodiversity environments have more rich soils that are better for farming. Similarly more biodiverse environments are more resistant to disease; Ash dieback disease that affects the Ash in Europe appears not be fatal to the tree in mixed diverse forest [1].

Diverse ecosystems are also more resistant to climate change [2], so there's that too.
