A contraversial issue nowadays is that if there are an increasing number of people who love to get a pet accompanying with them. My answer is exactly yes for I'm just a pet lover who is keeping a dog at home.In my opinion, there are two main reasons for why keeping a pet is becoming more and more popular.
 The first reason is the gradually improved afording ability. The economy of all over the world has made a remarkable progress in last several decades. People are getting more and more wealthy and it comes that the focus of people in their daily life has changed from material level to mental level. They are perchasing more mental savor, in the other word. For example,  they will choose to spend money for food in past on watching a film in a cinema, or something else like that. And pets, a great supplemental factor to increasingly lonely life, are being more and more popular without any surprises. When I studied an lived in Chengdu, I could usually see old people going out for a walk with a dog. They even had a seat together and chatted watching their pets playing. It was really a harmony sence. 
 The other reason is the advantage of pets that they are easy to keep. Take my dog as an example. My mom bought my dog back at a cost of just 100 yuan. And we feed it with the rest part of our dinner every day. In this way, we've saved a great number of money which can be used on its possible diseases. Dogs and any other pets usually have a good adaptability that ensure them live as longer as possible without a superb environment. I believe this advantage make pets easily accepted by most families since not everyone would spend a huge part of their monthly budget on a pet.
 The two reasons illustrated above are the two most reliable ones among all the reasons for people feeding more and more pets. Although a bit ridiculous, they are interesting.
