First I want to apologize if I sounded angry. I'm not trying to hurt any of your feelings- especially not the feelings of a Spirit SOTC fan! I remember seeing that in theaters. It's a great movie.
I did not know about the lionfish being introduced. Those are the strange-looking striped species correct? I don't think there is a way we could kill them since they're underwater (without hurting other fish) but maybe we should collect them from the waters. I know people like to keep them as pets.
I think non-native, invasive species should die out ONLY where they have been introduced. I do not hate them, and think we should kill them as painlessly as possible. I just think they are hurting the ecosystem, and therefore, other animals.
Think of it this way. Some people around here let their cats roam around outside. They kill birds and mice and other animals. That is wrong. Bring the cat inside so it isn't killing wildlife. Cats are carnivores, but at least feed them farm animals that do not have babies to take care of!
I realize humans are mostly to blame for bluebirds, but remember, the sparrows being here is because of humans too. Most animals that go extinct do so because of humans messing with their ecosystem. Even the wooly mammoth was hunted by us. I'm not saying sparrows are the only cause of bluebirds dying, but they are definitely not helping.
I know you weren't talking to me, but I have to say that I have heard great things about Salatin. He is right about everything being a sacrifice. Blades of grass give their lives to cows, which give their lives to us (And dogs, cats, etc), which eventually "become the grass" to quote the Lion King LOL. Even the soil and the water is alive, full of bacteria. It's said there's more than a million bacteria in one spec of dirt! It's amazing.
Roostersandhens, I have two things to say to you.
First, plants definitely feel pain. Plant a garden and you will see. They can be tortured. There is a new show on Animal Planet called Tree Houses or something. What the show doesn't say is that, sometimes the trees die under all that weight. If you have killed the tree and then used the wood, it could have supported the weight but a living tree cannot. The stress is too much and it will succumb to disease. Eating a carrot or tomato is no more or less pain-inducing than eating a rabbit or pig (Assuming it did not come from a factory farm). The creature still dies, but its death becomes our life.
Two,do not feel bad about killing animals when you have to. It is hard, yes, but in the end it is worth it. By killing one house sparrow you will save many future generations of native birds, Where I live, bluebirds are so rare, most young people have never seen one. You can buy a specially designed bluebird house, but house sparrows get into it instead. In the last year, more and more people have been chasing out or destroying sparrows and guess what? I saw the first family of bluebirds this year, that I have ever seen my whole life. You don't understand because sparrows are not so bad where you live, but believe me, they will take over if you don't do something about it.
It's like eating a farm animal. If we did not eat them, they would go extinct, It sounds strange but think about it. What if there were no pork farms or beef farms? The pigs and cows would go extinct. Go to the livestock conservancy website and look at all the rare breeds. Many of the pigs were bred to make lard for cooking, but now doctors say lard is bad for you, so guess what? Now these pigs are going extinct because no one wants them. If we support farms that raise animals for eggs or meat or other things, the farmers will have more money, and if they have more money they can breed and better provide for the animals, so that the next generations can have them too. I own a rare breed of meat goose. Today Americans do not eat geese, so they are rare- critically endangered. There are less than 500 in the entire country! They could be gone forever. That is unacceptable to me.
Let's appreciate plants, animals, bacteria, humans, and others for what they are- no more, no less.
