"Sorry ummmmm - don't see the connection (or disconnection) with 'we can speak' -- there has been a lot of communication and nothing happens. "
The existence of language as complicated as the ones that humans have developed is a pretty remarkable/unique feature of the human species, it's the source of our ability to innovate, empathise and civilisation generally.

I also don't see how your argument that 'the animals do it' works at all. It's also not uncommon among various animal species to allow their young to die if they're too weak. Shall we adopt this practice too? Most animals (though admittedly this seems to vary but I'm pretty sure this applies to pack animals as you're describing) don't appear to have self-consciousness, and therefore don't have individual personalities or awareness to the degree that humans do.

Personally, I'm unsurprised but a little disappointed by the finding that the majority of parents are (for the moment at least) in favour of CP. Neither does it surprise me that this has been found shortly after the riots - consider the tidal wave of depressing, stupid, knee-jerk public opinion which those events unleashed. I think we're going to be living with that for a while.
Because everyone is doing it and I want to satisfy my ego, I'll also share my top-of-the-head thoughts on CP.
I was miserable at school. I didn't realise how incredibly unhappy I was until I started looking back on it now in my 20s (having experienced some happiness as a reference point). Had CP been in place, I'm pretty sure I would've been reduced to a gibbering wreck and would likely be a very different person. I don't believe in using personal experience as the sole justification for arguments, but I'll admit that's a big part of what's behind my opposition to it - but there's also the fact that I've never, ever seen any convincing evidence that it actually works. The best anyone ever seems able to come up with is something roughly akin to 'it was better in the good old days', which I have no time for.
I'll also say that I find the infatuation with authority (and sometimes violence) in education policy that some people seem to have quite disturbing.
