Carless days in New Zealand are when the government asks people to not use their cars on a certain day or days of the week. This is because when lots of people use their cars, it creates lots of pollution, which is bad for the environment and can make people sick.
During carless days, people are encouraged to walk, bike, or take public transportation instead of driving their cars. This can help reduce the amount of pollution in the air and make the environment healthier.
Kids should remember that carless days are just like taking a break from using cars. It's important to take care of the planet and people's health, and finding other ways to get around can be fun and healthy too! So, let's all try to have some car-free days and help make New Zealand a cleaner and healthier place to live!
