Making no effort is not OK. Making effort with little to no insight to things wont help either.

For example that fish bladder comes from fish. That fish was probably killed for it's meat. So even if you're not using fish bladder in the beer clearing procedure, that fish will be killed and that part thrown away. Than you use some kind of substitute which has to be grown, or manufactured. That needs land, energy etc...

In short you will have a bigger impact on the environment, because the fish will be killed anyway. And now you have to produce extra filtering agents for the beer, because you will lose customers who like clear beer.

And all of this for a couple of vegan beer drinkers.

Well done.
