- air pollution; the bigger cities create lots of dust, there's always new building sites that contribute to dust and some of the working materials to pollute the air. Also there's big amount of vehicles that release toxic gases, as well as the industry.
- housing shortages; the more people there are at some city, the more difficult it is to have space for everyone, because usually the process of building new homes doesn't correspond with the amount of people coming in.
- overcrowding; the larger the population at some place, the more crowded it gets, be it in traffic, walking, in stores, institutions...

Answer:
A simple thing you can do is use less electricity. For example, people use electricity for light a lot and they can reduce that by just not using it in certain times like in the day time, they can open their windows for sun light and turn the lights on in night time. People also use too much electricity on gadgets and electronics and they can reduce that by just not charging them too often and using them a bit less. By doing these methods you can maybe save around 10$ to 100$ or even more.
