In 1962, the American marine biologist and writer Rachel Carson (1907-1964) published a book called The Silent Spring. In it, she wanted that the indiscriminate use of pesticides and weed killers was poisoning the natural world. Her pioneering book was fundamental in starting an environmental movement and in making ecological information accessible to the public.
Boudicca (d.61 AD) was queen of the Iceni, one of Britain’s Celtic tribes. When the Romans conquered Britain after 43 AD, the Iceni joined forces with them to defeat a rival tribe. However, the Romans then seized Iceni lands and flogged Boudicca. She led a huge revolt, destroying the Roman settlements at St. Albans, Colchester, and London. The Romans finally defeated the rebels, and Queen Boudicca killed herself by taking poison rather than risk being captured.
