This is a normal post Just a thought
Does the total weight of everything on the planet basically remain constant?

If 45,439,259 tonnes were added to the total weight of the world's population, this would not in fact make the planet heavier, as resources are finite and the weight would be taken by the surrounding environment - ie, 45,439,259 tonnes of chips

Any science people available for comment?

This is a normal post You're right

Mass is not gained or lost, just dissipated. However, that does add to a lot of water and other minerals, compounded hugely when less appetite equals less demand for further resources.

This is a normal post It does vary ever so slightly.
Sending rockets into space diminishes the planet's mass slightly; meteors add to it. There's a list of things that might make a difference, but the list is small, and the difference is smaller.

This is a normal post Yep, meteors burning up in the atmosphere,
trickle down to the earth as dust, and add about 25 tonnes each day.
