A: In my opinion, the most urgent problems are air pollution, contaminated food and polluted infant formula.

A: Air pollution is a great risk factor for multiple health conditions including respiratory infections, heart disease, and lung cancer. The human health effects of poor air quality are far reaching.
B: Yes, I agree with you that air is very important and necessary for human beings.
A: Food is also essential in people's life. Polluted food have dangerous effects on people's health. As the famous saying goes "Bread is the staff of life". Without food and air, people cannot live.

Children's health can be easily destroyed because their immune system has not fully developed. Adults should protect children rather than hurt them to make profits. What about you? What are your choices?
B: I think the most urgent problems are air pollution, poisoned water and contaminated food. As you said just now, air is essential in our life. Air quality has great impact on human health, especially on children's health, because children are outdoors more. They are more susceptible to the dangers of air pollution.
A: It's true. And children often have little knowledge to protect themselves from polluted air.
B: Water pollution is urgent because poisoned water cannot be used in agriculture and industry. The drink water in some cities has been polluted too. People have to pay much on drink water because many of them choose purified water in containers.
A: And the result is the cost of living expense is increasing.
B: Not only the cost of drinking water is increasing, but also the cost of eating food is increasing too. More and more people choose green food which is twice expensive than ordinary food. The government should take measures and solve the problems quickly.
A&B: It's the end of the conversation.
