When answering this question, you can discuss the environmental impact of current transportation methods, such as cars and airplanes, which contribute to pollution and climate change. You can also talk about whether small changes are enough, or if we need big, significant changes—like switching to electric vehicles, using public transport more, or even redesigning cities to encourage walking and cycling. You might also mention the challenges people face in making these changes, such as cost or convenience, and whether gradual or drastic changes are more realistic.

回答这个问题时，你可以讨论当前交通方式（如汽车和飞机）对环境的影响，这些交通方式导致污染和气候变化。你还可以谈论是小的改变是否足够，还是我们需要重大而重要的变化——比如转向电动汽车、更多使用公共交通，甚至重新设计城市以鼓励步行和骑行。你还可以提到人们在做出这些改变时面临的挑战，如成本或便利性，以及渐进式改变还是剧烈改变更为现实。
