Most of the mass extinctions of life on earth have been linked to meteor crashes volcanic eruptions ultra violet radiation climate change

Ima go with climate change because meteor crashes killed the dinosaurs but not every one believes that they existed volcanic eruptions woulds be it either ultra violet radiation couldnt be it so climate change is the answer

Unique question.well, using science, you cannot create or destroy even if you do eat yourself so you would not grow twice as big, nor would you disappear. you would stay the same but change states potentially, or at least change your appearance (obviously).hope this . keep up these unique questions.
