Rachel Carson and the Origin of Scientific Environmentalism | AMS OpenMind

In wars, insect-borne diseases killed more than bullets. During WWII, DDT, a miraculous insecticide, was used by the Allies to annihilate millions of insects transmitting malaria and typhus, aiding troop advancement. After the war, DDT brought prosperity to agriculture, making crops more profitable than ever. But a famous writer saw unexpected consequences. Marine biologist Rachel Carson had a gift for communicating science and a passion for nature. 🌿 Her talent took her from editing radio scripts for the U.S. Fish and Wildlife Service to becoming a successful author. Her second book, “The Sea Around Us,” was an immediate bestseller, and its film adaptation won the Oscar for Best Documentary in 1953. 🎥 In the late '50s, a friend wrote to Carson about many songbirds dying near her land after a DDT spraying. This led Carson to investigate the effects of this synthetic pesticide for four years. She discovered three important phenomena: DDT kills all kinds of animals, not just pests, so it should be called a “biocide” rather than a “pesticide.” It doesn’t dissolve in water and remains in the environment for years, weakening ecosystems. DDT contaminates food by accumulating in fatty tissues, affecting human health by causing cancer and genetic damage. Carson published her findings in “Silent Spring,” a book that shocked the public and demanded the use of safe products to deal with pests. The chemical industry responded ruthlessly, even discrediting Carson personally. But many scientists supported her meticulous work. 🌍 Ten years later, the U.S. banned DDT as an agricultural chemical. However, Carson’s vision went beyond pesticides. She wanted society to control its impact on ecosystems and led a global environmental campaign based on facts, not just feelings. 🌱 #RachelCarson #SilentSpring #Environmentalism #DDT #ScienceHistory #Nature #Conservation #Education #learnsomethingnew A video by @scienseed4294 Ventana al conocimiento

https://www.bigspeak.com/speakers/xiuhtezcatl-martinez/ A 16-year-old indigenous change agent, environmental activist, public speaker, eco hip-hop artist, and the Youth Director of Earth Guardians– Xiuhtezcatl (Pronounced “Shu-tez-caat") is a powerful voice on the front lines of the youth-led climate movement. He performs internationally at music festivals, organizes demonstrations, and has spoken at over 100 high-impact rallies, events and conferences around the globe. He and his brother, Itzcuauhtli, regularly give school presentations to ignite and inspire youth to step up as leaders and take action on behalf of the planet. Xiuhtezcatl gives presentations on fracking and climate change in schools and conferences nationally. His work on climate change has led him to become a youth plaintiff against the United States for failing to protect the atmosphere. To support this litigation, Xiuhtezcatl met with representatives from all three branches of government working to garner support and create a climate recovery plan based on NASA scientist James Hansen's work. Over eighty members of congress, including the Congressional Progressive Caucus, publicly supports the youth delegation. He also uses his passion for music to inspire his generation. In 2012, Xiuhtezcatl was one of the youngest speakers at the RIO+20 United Nations Summit in Rio de Janeiro, Brazil. He spoke on UN panels and side events, and had the honor of lighting the sacred fire with indigenous elders from Brazil. He is traveling and initiating international Earth Guardian crews around the globe to fulfill the Earth Guardians mission with crews in Africa, India, Australia, New Zealand, Germany, France, Mexico, and Brazil.
