Na szybko! Proszę◘ o sprawdzenie czy czasy są dobrze, ogólnie czy wszystko gra. HELP!In nowadays, having a pet is very popular. But This is connected with high responsibility, because it needs the best possible conditions to life and growth. There are Several Advantages of owing a pet. Firstly having a pet teaches independence and responsibility. Secondly, spending time with it gives a positive effect on atmosphere and provides a sense of security and gives self-confidence. What's more, some animals, mainly dogs and cats fulfill therapeutic functions, for examle, cats like to snuggle up on human patients, making them relief, because of this direct contact with the cat patients improves their mood and improves the course of the disease. Dogs and can be guides for the blind and I can save human lives. However, there are also Several major arguments of owing a pet. Firstly, animals bring different dangerous diseases. Secondly, is associated with them more expensive. So they should be given food and care (eg visits to the vet, buy food, toys). To sum up, owning a pet is associated not only with pleasure but also with the duties and costs. In my opinion pets should hold people responsible and liable for their well-being.
