To float in air, the density of the balloon (divide the combined mass of balloon + contents by its volume) must be LESS than that of the same volume of air. If the gas inside the balloon has a greater density than air, the combined object (balloon + contents) won't have less density than air, either.

What do you think makes balloon stay up?
balloon stay up because of the air inside it. to make the balloon stay up the air should be light. inside the balloons you can find the air we called helium. helium is a light air that makes the balloon stay up. that's why if you blow the balloon it wont float because the air that comes from your mouth is not helium but carbon dioxide and carbon dioxide is heavier compared to helium so it wont float.

How does cutting down forests affect the carbon cycle?
It affects the carbon cycle because when photosynthesis happens plant take in Carbon Dioxide and release oxygen. When the trees in the forest are cut down photosynthesis is reduced. Meaning, carbon dioxide will remain in the air that we breathe.
Why descover carbon dioxide?
carbon dioxide of coarse is able to kill a person so scientists are finding gases liquids and solids that are able to kill people and in doing so help prevent it like led if it got inside you you could die but it depends on the dose of the led that entered your body. and carbon dioxide is good too it helps vegetation grow. so it is bad and good but i still wont go sticking your head in a all rich carbon dioxide environment.
