Define what ‘we are not being good to our planet’ means. Look at Jupiter, it is nothing more than a huge ball of hydrogen and helium gas with a solid core. One of the most hostile places in the solar system.
Earth has been through asteroid collisions, extreme temperatures, even a collision with another planet. You can’t be ‘good’ to a planet.
Also, what makes it ‘our’ planet? Because we’re the dominant species? Dinosaurs have lived on Earth for over 150 million years, we probably don’t even have 1% of that length.
