After a 1991 cyclone killed roughly 138,000 people, Bangladesh planted around 200,000 hectares of salt-tolerant keora mangroves along its Bay of Bengal coast. When a comparable storm hit in 2007, the death toll fell to about 3,500.
China's Loess Plateau shed roughly 1.6 billion tonnes of silt a year into the Yellow River for millennia. Then Grain-for-Green, check dams and terracing cut that discharge by nearly 30 billion tonnes cumulatively in two decades — with hydrological costs that are still being counted.
Twenty metres under a Romanian wheatfield, Movile Cave holds 35 species found nowhere else on Earth — a food web powered by bacteria that eat hydrogen sulphide instead of sunlight, sealed off from the surface for roughly 5.5 million years.
A volcanic lake in Cameroon turned into a lethal trap when the invisible gas trapped beneath its surface suddenly rose to the top, suffocating thousands in their sleep.
Astronauts on six-month ISS missions come home up to 3 percent taller as their spinal discs expand without gravity's compression — a temporary stretch that quietly reverses within months, often bringing back pain in its wake.

The future of travel beyond Earth.
Space Travel is an independent publication covering human spaceflight, commercial missions, rocket technology, launch operations, and the engineering driving the future of exploration. The site pairs a deep archive with current reporting on the agencies, companies, research programs, and technical breakthroughs shaping how people and payloads move beyond Earth. We employ modern AI technologies to support our editorial workflows; every published piece is editorially directed and reviewed.
