How old can the Earth live to be?

If I learned anything from the heart-wrenching movie The Lion King, everything that lives has to die; it’s the circle of life. Well, our planet is kind of like a living thing, so how long until it goes to a better place? According to researchers from the University of East Anglia in the United Kingdom, Earth should sustain life for another 1.75 to 3.25 billion years (assuming humans don’t blow up the planet before then).

You see, it’s currently orbiting around the Sun in what is know as the “habitable zone.” This region is just close enough to be not too hot nor too cold, and perfect for liquid water. If Goldilocks were picking planets, she would say the distance is “just right.” However, in about 1.75 billion years, the Earth is slowly going to creep closer to the Sun and enter the “hot zone.” When it does, temperatures are going to be so hot that the ocean water will evaporate. Hopefully humans will be colonizing Mars by then!
