Our time.  Many animals do not have a home. Many people simply kicked them out. Although they could give them away in good hands. Thousands of dogs and cats die every day, and all of these deaths are usually associated with Drugs. Why do people even dare I say throw away used syringes to drug addicts. We all understand that they are drug addicts, but it should be stopped. For this we must make a special school who can then think it's funny, but when you think We all want the animals to be with us. But if you think about what we give them, we are with them to do so. And then the animals - loyal creatures, they trust us, they think we do not hurt. But life is not a fairy tale, once the street dog died. Have you ever wondered which is why, of course not, you do not matter, what happened to her, you just bypass. Every life is important no matter who it is or what it is alive. And I will not let that they died. Drugs is harmful to all living creatures. Think about it I do not care, they are listed as endangered. It is a living creature.

There are two types of animals: wild and domestic ones. Wild animals are called so 'cause they live without a man in forest, deserts etc. In other words, they don't need a human to survive. Domestic animals live with a man, they are tamed by him. There are many rare animals around the world. These animals are called threatened species. People hunt them and kill them for leather, meat and fur. Except of this, the natural habitat of rare animals is destroyed. So they can't breed. For example, among the rare animals there is a sloth, an anteater, a duckbill, a Tibetan fox etc. All rare animals do exist but there is a real threaten of their disappearance. We must protect them to keep these species for next generations. Перевод нужен? :)
