The earth’s gravity is increasing as space dust and meteors are constantly added to the total mass of the earth.

Not to mention the population increase each year :).

Yes, but we're losing mass as we lose atmosphere. I think it's a net gain, but there are multiple processes working no the total mass of the system.

Some scientists claim that the earth is losing more mass than it’s gaining, especially via the escape of hydrogen and helium from the planet’s gravity well into space. The estimated 50,000 metric tons of that loss offsets the 40,000 metric tons of mass gained from space dust et cetera, per that set of calculations.
