Indeed. Even if eating meat caused zero deforestation (directly or indirectly), it's super inefficient. If everyone stopped eating meat, 75% of the land used for farming could be re-wilded. That land area is something like China, the US, the EU, and Australia... combined.

I'm not vegetarian, but after seeing the results of deforestation first hand I've reduced my meat intake substantially. Side benefits included improved cooking abilities and lost weight without trying.
