Yes, I think people really need to change how they travel if we want to protect the environment. Cars and planes cause a lot of pollution and greenhouse gases, which make climate change worse. If more people used public transport, cycled, or walked, it would help reduce emissions. Also, electric cars are much cleaner than petrol ones. Some cities have already shown that air quality can improve a lot if people use greener ways to get around.

No, I don't think drastic changes are always needed. Not everyone has access to good public transport, especially in smaller towns or rural areas. Some people really need cars for work or family reasons. Making big changes can also be expensive and inconvenient for many people. Even small steps, like carpooling or using cleaner fuels, can help the environment without causing too much trouble.

I think it depends on where you live. In big cities, drastic changes might be needed because there are so many cars and a lot of pollution. But in the countryside, people might not need to change as much because there are fewer transport options. Also, technology is getting better, so maybe gradual changes will be enough if governments support them.
