Just to be clear, I am totally against zoos and aquariums. Just wanted to mention that a lot of evil activities in this world are caused by 'demand and offer'. The issue you mention, zoos, aquariums, killing of elephants, rhinos, and other animals for their furs and tusks, oil extraction, plastic pollution, onlyfans, etc would all not exist if no one was willing to pay for these things or services.

So what I wanted to say is that change comes from consumers, and as such if we choose to say no by not giving our money for anything immoral, we can kill those activities.
