Save the Moon

The moon revolves around the earth, and the gravity of the earth and the moon causes the circulation of the earth's atmosphere, the movement of ocean currents, and the changes in tides... What would it look like if one day the gravity of the earth and the moon changed drastically? The answer is that earthquakes and volcanoes will continue to erupt; super hurricanes and tsunamis will arise; Newton's laws will no longer apply; science and technology such as aerospace communications will become useless; high-rise buildings will tilt and collapse... There will be no tomorrow for mankind! Of course, this is not science fiction, a quiet change is coming quietly...
