Yeah the picture doesn't really present the issue. The 60% livestock isn't comparable to wild life. It's much worse than that.

I could also say that 100% of bricks are man made and there are no wild bricks.

Similarly, live stock is a product, that shouldn't and wouldn't exist in the first place. It does not represent animals in a way that is comparable to wild life that have full lives.

The 60% livestock does not live long happy lives. It's constantly being replaced by new livestock.

So sure at any given moment there might be 60% mass of animals classified as livestock, but if we were to count the actual number of animals over a year, it would be closer to 100%.
