The appetite for speedy package delivery is skyrocketing around the planet. Americans do more than 15% of their shopping online, with digital purchases of groceries, shoes, pet food and other goods quadrupling over the past decade to $1 trillion a year. Global e-commerce is expected to grow at more than twice the rate as offline purchases, and, by decade’s end, 25,000 packages will be shipped every second, according to an analysis by environmental group Stand.earth.
