Lucianne Walkowicz: Let's not use Mars as a backup planet

The video discusses the balance between exploring new planets and preserving Earth. It highlights NASA's Kepler mission, which has discovered many potential planets, and the environmental challenges Earth faces. The speaker, an astronomer, emphasizes the importance of appreciating Earth while exploring Mars and other planets. They critique the idea of Mars colonization as a backup for Earth, advocating for planetary preservation alongside exploration. The video concludes with Fermi's paradox, questioning why we haven't found alien life, and stresses the need to safeguard Earth.
