What do you think about cities in the future? Will they be better or worse? giúp mk với mk đag cần gấp

The thoughts of people on future cities vary greatly. Those who are pessimistic believe that as pollution in our cities increases, it will make them unsafe and unhealthy to live in. Pessimists point out that over the past 20 years, both global warming and pollution have increased significantly, but that governments lack the means to effectively manage them. There are no indications that this issue will be resolved any time soon. Additionally, an increasing number of people are moving to major cities from rural areas in search of employment. Cities will consequently overpopulate. More people, more waste, and more traffic are the results of this. These variables collectively will increase pollution. On the other side, optimists think that because of significant advancements in science and medicine, city dwellers will enjoy a better quality of life. People will receive better, quicker, and more effective medical care thanks to modern equipment and well-equipped hospitals in urban areas. How about issues with the environment? Additionally, optimists believe that scientists will discover methods to lower the cost of renewable energy sources and make them accessible to everyone. In the next 20 years, they anticipate that these energy sources will gradually replace fossil fuels including gas, coal, and oil. The environment will then be cleaner and healthier for city people.
