Because it's an unnecessary waste of life, as well as a potentially painful process for the animal. You don't need fur-synthetic furs work just as well, and to skin an animal for something so incredibly unnecessary is wrong. Plus, before the animals are skinned they are often put into tiny cages, outside, in rainy and/or frigid weather, and are generally abused. if you want to see it for yourself just Google things like "fur farms abuse" or go to the PETA website for more information.
They're genetically mutating goats to produce supersilk, which is (5x?) stronger than steel. The genetic mutation is what Animal Rights' activists are concerned with.
Animal activists are against the use of fur and silk because to get the fur or silk, the animal has to be killed in most cases. Wool from sheep can be gathered without killing the animal. The same goes for llamas and alpacas.
Silk is spun by silkworms as a protective coccoon, and in order for the silk to be harvested at the right time, the silkworms must be boiled from the coccoons. They are usually eaten in areas where food is scarce, but animal rights activists believe it is unfair to kill all of the silkworms in order to obtain their meat and silk.
Silk is obtained by painfully boiling silkworms alive.
Silk is created by boiling silkworm cocoons. Silkworms are animals too - sentient creatures who feel pain and thus deserve to be protected. Also, silk is derived from silkworms, and many animal rights activists believe that humans are stealing the silk from these worms, in the sense that they certainly are not making it for us. Also, the silk industry does not have optimal habitats for silkworms - lack of natural sunlight, diet, etc.
Many animal activists and vegans oppose using silk from silk worms because they feel that they are harming the animal or distrupting the natural life of the animal in the process.
Because if there weren't there would be allot more endangered species.
The cocoons of the silk worms are submerged, still alive, mind you, in boiling water so the silk can be extracted. I have seen it on tv before. When the cocoons are put into the boiling water, they start jumping around trying to escape.
Silk is animal protein, from silk worm cocoons.
Silk is animal protein, from the silk worm.
Silk contains animal protein, from silk worms.
Silk is spun for the cocoon of the silkworm, an insect, before it can turn into a moth. It's vaguely similar to spider web. The silkworm is fed on mulberry leaves.
