Hear, hear. I can't for the life of me understand why that experiment isn't being tried hundreds of times, all over the world. Learning how to create sustainable sealed ecosystems is one of the most important things we can do. Quite apart from the valuable knowledge we'll gain, once we get that nailed we can seed those suckers all over the place - South Pole, Sahara, orbit, Mars, upper atmosphere of Venus...

The really weird thing is we already sort of know how - "bottle gardens" are a thing. It seems to be mainly a question of scale. So why aren't we building bigger and bigger bottle gardens?

Apparently, after giving it one little shot here in a convenient location and failing miserably, we think we can just skip straight to Mars and be successful there.

There are four additional experiments listed under this link:

So that's at least five.

In Poland, there's a Mars-like base being built right now, though not aimed at testing self-sufficient ecosystems but equipment and work procedures of potential off-world colonists. My guess is there's more of such little-known projects happening.

The point being, the number of projects related to living off-world is slowly increasing, and my guess it will only go up as the perspective of Mars mission comes closer (SpaceX is doing a lot of good work making this close to "very soon" in peoples' minds). So we're definitely not "giving it one little shot".
