What plays a vital role in our existence on planet earth atmosphere or gravity if gravity becomes like that of moon(1.6) and atmospheric pressure remain same(like on earth) what would be its impact on?

If gravity were to decrease to that of the Moon (1.6 m/s²) while atmospheric pressure remained the same as Earth’s, it would significantly impact life and ecosystems. Lower gravity would reduce the weight of objects, affecting how organisms move and grow, potentially leading to taller plants and different animal adaptations. However, maintaining Earth-like atmospheric pressure might not be sufficient for sustaining current life forms, as many biological processes are influenced by gravity, such as fluid circulation and muscle development. Overall, such a scenario could lead to a drastically altered environment, with unpredictable consequences for existing life.
