Can we live without trees?

No, humans cannot survive long-term without trees. They are essential to life by providing oxygen, filtering breathable air, regulating the climate, and storing carbon. Their removal would trigger catastrophic drought, massive flooding, soil erosion, and the collapse of ecosystems and biodiversity

Can we live without clean water?

Humans cannot survive without water, and lacking clean water is fatal. While a person might survive for 3 to 7 days without any fluids, drinking contaminated water causes severe disease and death. Globally, over 2 billion people lack safe drinking water.

Can we live without other living animals?

No, humans cannot survive long-term without other animals. While we might survive a few weeks, the collapse of ecosystems—specifically the loss of pollinators (bees, insects) and decomposers (worms, microbes)—would stop food production, destroy soil quality, and cause widespread famine and ecological collapse within months.

David Attenborough

Born May 6th 1926

English broadcaster, natural historian and writer.

His presenting career began as host of Zoo Quest in 1954, and has spanned eight decades; it includes the nine documentary series forming The Life Collection, Natural World, Wildlife on One, the Planet Earth franchise, The Blue Planet and Frozen Planet. He is the only person to have won BAFTA Awards in black-and-white, colour, high-definition, 3D and 4K resolution. Over his life, he has collected dozens of honorary degrees and awards, including three Primetime Emmy Awards for Outstanding Narrator and one Daytime Emmy Award for Outstanding Daytime Personality – Non-Daily.

Sir David Attenborough's older brother was Lord Richard Attenborough (1923–2014), a renowned actor, director, and producer known for films like Gandhi and Jurassic Park. The brothers were giants in their respective fields—one in cinema, the other in natural history broadcasting.
