You've got the wording correct--natural evolution sounds so much less alarming. This article is chilling. Who calls the shots, where is the line drawn?
Please read the article, it's states quite plainly
Examples include extremely premature births, where children suffer brain damage from bleeding and convulsions; and diseases where a child could only survive on life support for the rest of its life such as spina bifida.
I would think this to be merciful and humane. I would rather die peacefully from a sedative than endure unending pain and suffering. If you prefer to keep a child alive, simply because we have the technology to stave off the enevitable, I must disagree with you. To keep a baby (or anyone else alive) using life support, knowing that every moment will be filled with unending pain, and knowing full well that the entire life of the person will continue in pain, is neither humane nor compassionate.
