Growing numbers of travelers are deciding not (fly) in order to help save the planet even if it means (spend) days on a train. The no-fly movement is small but many people have joined it think it will eventually receive same attention as the no-plastic or less-meat movements because of flying's 2% (contribute) to carbon emissions, which they say could rise to 16% by 2050. Some supporters suggest that people should fly no more than once per year and any further flights should be taxed. Critics of the movement, however, argue that most flying is done by small numbers of people when (compare) to other forms of transport and so flying is an easy target. Much more environmental damage is done by cars they argue. But people won't target 7 (driver) because the majority of people drive. In addition, the no-fly movement (lead) by people who don't really need to travel very far and have plenty free time to spare. Most people who fly, they say, (rare) have time to spend extra days getting to destinations and employers are unlikely to give employees extra time off so they can be kind to the environment.
