For example, noise produced by snowmobiles might affect animals to alter their natural activity patterns. Transport emissions and other emissions from energy production are related to photochemical pollution, acid rain and global warming. Air pollution from tourist transportation has effects on the global level. Some of these effects are specific to tourist activities.
