For millions of years, nature has basically been getting by with just a few elements from the periodic table. Carbon, calcium, oxygen, hydrogen, nitrogen, phosphorus, silicon, sulphur, magnesium and potassium are the building blocks of almost all life on our planet (tree trunks, leaves, hairs, teeth, etc.). However, to build the world of humans — cities, healthcare products, railways, aeroplanes and their engines, computers, smartphones — we need many more chemical elements.

Science histpry often doesn't visibilize all people equally. Some of them people who have inspired big changes, in this case in ecology and evolution. Many of them are women, and that is why we want to take advantage of the International Day of Women and Girls in Science to make them known.
