British sperm donations face impotency

Apparently, sperm donations in Britain—and in London especially—have fallen so dramatically that it can be quantified as a critical shortage, and a radical overhaul of sperm donation services is required.
Now for the million-pound question: Why, exactly, is this a bad thing?
You only have to look around you at any point in the day or evening to conclude that Britain certainly does not, in any way classifiable or conceivable, have a fertility problem. Little buggers are everywhere, getting pushed along the sidewalks in their oversized prams by chain-smoking mamas or picking their noses as they waddle four-square along the sidewalks on the way to school.
I wonder if the freefall in sperm donations is in any way related to the fact that over 50 percent of British adults view children as "animals"? Which really distresses me as I consider that a grevious insult to animals.
Of course, mind you, I don't necessarily consider children on the same level as cockroaches, but all people in general. I found myself nodding solemnly while reading this column by Charlie Brooker, in which he opines: "Two's company. Three's a crowd. And whoever they are, I don't trust them. Yes, in the ever expanding list of things I don't 'get,' the most crippling entry has to be people. I don't get people. What's their appeal, precisely? They waddle around with their haircuts on, cluttering the pavement like gormless, farting skittles. They're awful."
Anyway, getting back to sperm donations, that's one thing that I've never gotten. Who in their right mind wants to consider the fact that somebody, somwhere, will be conceived carrying half their genes, possibly even their same facial features, hair and eye color, blood type and the same curious inability to not say "heeeellll, yeaaah!" at the end of every conversation? Honestly, who can be comfortable with the thought of spreading themselves around without even enjoying the so-called action? (Don't get me wrong: I'm very much a keep-it-in-your-pants sort of guy. I simply ask on a theoretical level.)
On a more serious note, sperm donation also encourages single motherhood. I cannot in all honesty say that I am a fan of that lifestyle. There is definitely a straightforward relationship between the "children are animals" sentiment and the emotional effects that single motherhood creates in a child who, through no choice of his or her own, has been denied the vital male influence.
The article cites the removal of anonymity in 2005 as the biggest reason for the nose-dive in sperm donations. In other words, once a child born in 2005 or after turns 18, they can chase their sperm donor down. This was just the sort of thing sperm donors never had to worry about in the past.
Which leaves me to conclude one salient point about all this: For once, this Labour government actually did something good. Only the sperm banks would disagree.
