In February 2016, Death Valley in California (the place where the hottest temperature ever was recorded) had a “superbloom” as millions of seeds of desert ephemeral plants germinated, leading to a massive floral bloom. See pictures and a video of this once-in-a-decade event.

If a few decades ago environmental and climatic changes were the remit of scientists and activists only, now concerns over the future of the planet have gone mainstream.
Climate change and industrial pollution are now threatening the availability of food, and given the current rate at which humans are multiplying, within a few decades there may not be enough food to feed the world’s population.
Now scientists are racing to protect our most precious asset, the world’s plants, 20 per cent of which are currently threatened.
Following the publication of one landmark study showing how plants’ diversity is under- represented in the world’s genetic archives, and how this could spell disaster for food security in the decades to come, we traveled to the world’s largest seed bank to investigate.
