Earlier this month, I saw a video about terraforming and really made me start thinking. First, take a spin with the video if you are interested in our species' future on our home planet Earth.
The video talks about terraforming options. This includes Mars, Venus, Titan, and Europa. To be honest, I always thought that we wouldn't need another Earth for a good 5-7 billion years. That's when the sun will expand until becoming a white dwarf. In this expansion, earth would die. But if we continue with how we are treating Earth today, the expiration date is much closer. It's still well after my life span on Earth, but it's harrowing to think that humans might cause the demise of our planet.
