Cymothoa exigua slips through a fish's gills, drains the blood vessels feeding the tongue until the organ withers away, and then hooks itself into the empty stump — the only known animal that functionally replaces a host organ.
Beneath the mud lies a carbon bomb that makes rainforest destruction look modest by comparison.
Pando has been regrowing itself from the same root system for somewhere between 16,000 and 80,000 years. That range is not a rounding error, and researchers still cannot narrow it.
After the 1995 floods forced 250,000 people to evacuate, the Netherlands stopped raising its dikes and instead spent €2.3 billion giving its rivers more room. Here is how the Room for the River program actually worked — and what happened when the water came back in 2021.
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.
