Because it will give you Green Credentials which are very fashionable these days. And it will give you an excuse to show off your bod in Spandex cycling clothes

Seriously, if it suits you then it's probably good for your health (as long as you avoid the danger of motorised traffic), and it's a relatively cheap way of travelling short and medium distances. I'm having to limit my cycling because of doctor's orders (I'm getting over sciatica in my leg), and the bike I own doesn't suit me very well, which puts me off bothering, but in principle I'm all in favour of cycling. But if you find you don't like it, it's not necessary.
