Yes, they have done it, the act of ecocide. It was predicted almost a year ago when it was first reported that the Russians had mined the dam. They've been preparing for it. Over the past few months, they have been draining the reservoir while simultaneously filling all reservoirs in Crimea, because blowing up this dam means no more fresh water supply to Crimea. So everyone who claimed that Russia invaded Ukraine to secure fresh water for Crimea can now go fuck themselves.
Of course they first claimed it was Ukraine's doing. Although some occupiers already happily admit that it was russia who blew it up, and call for blowing up more of Ukraine's infrastructure.
UPDATE: video evidence that the russians did in fact blew it up, and it wasn't destroyed due to any shelling from the Ukrainian side
It's typical russian scorched earth tactics. Blowing up the dam can possibly prevent the Ukrainian army landing on the left bank of the Dnipro, and it frees russian troops from the left bank, meaning they can be sent as reinforcement to other front lines, for example, in the Donetsk region.
It is probably the greatest ecological catastrophe since Chornobyl, with thousands of people affected, left homeless, entire villages destroyed probably forever. But the russians don't give two fucks about that. They don't care about any life. Their main objective is not necessarily to claim the land for themselves, but rather to ensure it is not Ukrainian. If they cannot have it, they want to leave it uninhabitable.
