Salt is harvested from briny ocean water and underground deposits

Mostly sodium chloride, this compound is produced for human use by collecting seawater in shallow pans and allowing the Sun to evaporate the water until crystals remain. Underground rock salt is mined, crushed, and purified from deposits left behind by ancient seas that have dried-up.

China operates multiple different sovereign wealth funds, primarily backed by profits from a trade surplus

Unlike other countries that primarily use profits from natural resources, China's sovereign wealth funds are fueled by the country's mounting trade surplus. Among the two largest are the State Administration of Foreign Exchange (SAFE) fund and the Chinese Investment Corporation (CIC). China also operates the Silk Road Fund, a strategic investment initiative that backs infrastructure creation in developing countries.

Visualizing the built world compared to the natural world

In the last century, humans have covered the Earth in 1,300 metric gigatons of built material, known as technomass. That amount is more than the Earth's entire biomass at 1,100 GT, which includes all living organisms. To get a sense of the scale of this comparison, click through this striking, simple visualization showcasing the various organisms comprising biomass as well as the materials making up the technomass.

China makes 90% of the world's fireworks, with Liuyang as its production capital

How microchips are made

Our increasingly electronic world depends on tiny devices called microchips to function. It takes half a year to create one, which is approximately the size of a fingernail. Engineering them is a highly involved process that starts with silicon-rich sand and eventually turns into billions of transistors packed into one small area. Watch this video to understand the complex feat of creating microchips and how they’re relevant to our daily life.
