People are killing animals because they want to make furs from them. It's dangerous because the animals can become extinct. In spite of bans people are killing animals and they are poachers.
We can organize a campaign for the thing of animals, for example a Day Without The Fur. We don't like people which are killing animals and we ask them to stop to do it.
