没有任何实质数据,楼主不要张口就来。先不说飞机燃油是不可再生资源,且污染环境,战时美国能源卡脖子等隐 ...
The systemwide increase was the result of a 3.0 percent rise from 2016 in the number of passengers on domestic flights (741.6 million passengers in 2017) and 4.8 percent growth from 2016 in passengers on U.S. and foreign airlines' flights to and from the U.S. (223.4 million passengers in 2017) (Tables 1, 1A, 5).
这是美国交通部的数据。
美国3.2亿人,一年坐差不多2.7次飞机。 |
