Consider the birth rate and death rate when doing calculations. What other events effect the weight?

The Earth doesn't weigh anything. It is floating in space and you need gravity to have any weight at all. It's mass may vary but it would depend on each person born and dying, each tree cut down, animal made extint... However I don't believe the mass changes at all unless a meteorite lands from space. Everything existing on earth was created on earth and therefore must have been created from something else that existed on earth already. The matter to make it up must already have been here before it existed.

Earth diameter increases about 25 cm every year, and as you can conclude it weight increases proportionally. The reason of that is not the increase in population, but that the green cover of our planet traps the sun energy and converts it to carbon systems which are trapped in our planet. That’s the only reason worth mentioning leading to increase in the weight of planet. While the increase of population increases consumption which means the total mass of humes grows while the total mass of things we consume like fishery for example goes down.
There are other things apart of sunlight leading to increase/ decrease of earths weight but there are so small that they are not taken into calculations unless we are talking about a long run, like at least 1000 years.

No. What makes up animals is the water and food the mummy eats. flora are created from water, carbon dioxide from the air, and a few minerals. those concerns are already in the international, so there is no strengthen interior the earth's weight.

Earth is not a closed system.
Meteors and (space) dust add approx. 10 tons per day to the weight of the earth.
However, biological systems are as others have stated above. Nothing lost nothing gained.

Eco system, everything gets recycled, molecular structure just changes. Example: every drop of water on planet earth is the same amount since earth formed. No more, no less. So I'd say no, about all I can think of that would increase the weight of the earth is when meteorites, etc., hit/land on it.

no as there is only a set amount of matter according to Einstein and also the every action creates a opposite blah blah blah... and its such a small amount it would not be possible to measure it. if every person on earth stood side by side they would all fit on jersey...that's how small the human race is compared to the size of the earth, its like a matchstick head compared to a football and it makes you wonder why we are supposedly having a over population problem.

No. You cannot create matter. You would have to increase the amount of matter on Earth for it to gain weight...i.e, mass.

No. Because the food is returned. Dust from space, gas escaping into space.

matter can not be created or destroyed, it can only be changed around. the only time earth loses its weight is when we send things into space and that is not enough to do any thing.

The mass of the earth will remain constant. Matter is neither created nor destroyed.
