Are you suggesting fewer pregnancies is a good thing in and of itself? If you mean unwanted pregnancies (i.e. unwanted by the participants, especially the prospective mother), then I agree.I'm firmly in the pro-choice camp there.

As to your other point: certainly alcohol CAN be toxic in a number of circumstances and no one should feel obliged to consume it. But as a treat, as a way to relax after a stressful day, as something that tastes good and is a great accompaniment to a nice meal ... I see nothing wrong with that. No, bodies don't need it although I'm betting that at least before modern-day sanitation, it was safer to drink ale than water!
