Tourism is big business around the world. The World Tourism Organization found 1.4 billion people traveled in 2018 — just on vacation. Add to that the business travel, daily commuters and day-to-day moving about in our own communities, and it's safe to say that people across the world are really on the go.
But what happens when all of that movement stops? As this global pandemic shutters cities with curfews and lockdowns to protect its citizens, it may also be protecting Mother Earth in the process.
From satellite images to people posting about bluer skies and near-empty streets in places like New York, not traveling may actually prove that human impact on the planet is greater than we imagined. Just see for yourself.
