extractive tourism noun [U]
UK /ɪkˈstræk.tɪv.ˈtʊə.rɪ.zᵊm/ US /ɪkˈstræk.tɪv.ˈtʊr.ɪ.zᵊm/
the situation when too many people visit a place on holiday, so that life is made difficult or impossible for the people who live there

a flow of air that stays around a single aeroplane passenger and helps to prevent viruses from spreading to other people on the plane

It claims to keep coughs and sneezes within the confines of a single passenger before removing them via the plane’s air filtration system.
