First of all, the release of most people now is to emancipate their minds, and there is no real "release" in the original intention. Why is there no intention to release? What is release? Jide? If it is really a virtue, then just releasing some animals, and there is no so-called virtue-accumulating behavior in daily life, then releasing is not necessarily a virtue for yourself. I just got rid of some unforgivable things I did for myself. Of course, there are also some people who are really releasing, and they are releasing in good faith.
Then before the release, I didn't learn the knowledge necessary for the release, which led to the release becoming "killing".
1, released animals can't adapt to the released environment: some people buy some animals in the market, just find a place to release them, or release them in a place they feel good about. There is no actual understanding of what kind of ecological environment the animals to be released need to survive. This practice is actually indirect killing, because you put them in an environment where they can't survive, and the final result is to die there.
There are many such examples. For example, someone bought some freshwater fish in the market (he probably didn't know it was freshwater fish) and then released it into the sea or salt water rivers. Because freshwater fish can't live in salt water, the final result is death. Another example is to buy some rabbits in the market and put them in the depths of Shan Ye forest, because there are many carnivores in the depths of Shan Ye forest, and rabbits have no viability. Rabbits will be eaten by predators before they are put in. It feels like it's not releasing, but delivering food to predators!
2. The released animals destroy the released ecological environment: As mentioned above, the person who released them did not have enough necessary knowledge to release them, and put an animal that should not appear in that ecological environment there, which led to the destruction of the original ecological environment by the last released animal, which is also indirect killing.
I remember watching a video that said there were no fierce fish in that river (I don't remember the specific name of the fish), but I don't know who put a few in that river. A few years later, countless fierce fish appeared in that river, and they ate all other local fish (the fish that originally lived in that river) badly. And most importantly, fierce fish will bite people and do great harm to local people. So, don't let it go. Otherwise, it is not a virtue, but it will become immoral.
Finally, the real release is not to go to the market to buy some animals for release, but to proceed from the root and not to kill animals maliciously. If you don't get caught, you don't need to let it go, do you? Therefore, the ultimate significance of releasing animals is to start from the root causes and reduce the killing.
