Answer: use the stores plastic bags.
In order to reduce our carbon footprint in the world, individual action is necessary. There are many things that people can do to contribute to the protection of the environment. Using mass transit is one option, as it means that less cars will be on the road. Switching to reusable water bottles instead of plastic ones is another good contribution, as single-use plastic is a significant pollutant. Turning off unnecessary lights helps us save electricity. However, using plastic bags from stores is not a good option as it increases our consumption of plastic, which is damaging to the environment.
