While the answer may seem obvious, in an era of misinformation, it may be hard to find the facts & science. Climate change refers to long-term temperature & weather shifts, which can occur naturally but have been mainly driven by human activity since the 1800s: www.un.org/en/climatech...

Jane Goodall said she would launch Trump and Musk on one-way trip into space
Primatologist said in interview released after her death she would also put Putin, Xi and Netanyahu on that spaceship In a lifetime studying the behavior of chimpanzees, Jane Goodall became something of an authority on the aggressiveness of alpha male adults. Now, in an interview released just days after her death, the famed primatologist reveals what she would do with Donald Trump, Elon Musk and other human beings she saw as showing similar traits: launch them on a one-way trip into space. The insight into Goodall’s thinking comes in the Netflix documentary Famous Last Words, recorded in March and kept under wraps until her death last week at the age of 91. Continue reading...
