TRIBUTE TO RACHEL CARSON. By reading the kids book “Rachel Carson and the book that changed the word”, this video explains the story of the biologist and conservationist Rachel Carson, who discovered the environmental and health problems caused by pesticides at the beginning of S. XX. |
Water pollution with pesticides and other toxic substances not only affects aquatic organisms, but also poses a considerable risk to organisms that consume them, such as birds, mammals, or even humans.
As Rachel Carson discovered, once in the water, some contaminants that do not mix well with water are very persistent and difficult to degrade. These contaminants accumulate along the food chain, exponentially increasing their concentration with the trophic level of each organism. In 1962, Rachel Carson published the book titled Silent Spring. This book is considered one of the most influential environmental books in history and deals with the significant impact that humans have on ecosystems. Thanks to her research, the widespread use of pesticides and chemical substances that contaminate aquatic ecosystems was curbed, and had a significant impact on the environmental movement.
Prolonged exposure to pesticides and high concentrations found in organisms at higher trophic levels, such as humans, can have harmful consequences for human health. This is especially relevant for women and the future of their offspring, as exposure to contaminating substances during pregnancy can have detrimental effects on fetal development. The effects of pollution can be stored and affect organisms and humans if we do not curb the production, exposure, and dispersion of these compounds in the environment. |
