Hmmm I am not sure I understand your question! Are you asking about the number of humans living in earth increasing more and more? It is true that the population of the earth has increase a lot over the last several decades. This has also lead to many other animals going extinct because the way in which we use and manipulate the environment for our benefit is frequently bad for other animals on the planet. So I am not sure how the mass on earth changes exactly when the number of humans changes…. But overpopulation is certainly something to worry about specially when there are many of us that do not care about the earth!

An other interesting thing to think about is that when living forms die there is a recycling of mass and energy. So for example when insects or animals die their mass turns into food for plants and that helps the plants grow which then provide food for other animals and humans and so on. So there is a kind of cycle going on when it comes to mass on earth ;]
