Oxygen
Atoms are not constantly being destroyed and recreated. According to the law of conservation of mass, atoms cannot be created or destroyed, only rearranged in chemical reactions. However, the nuclei of some unstable atoms can undergo radioactive decay, releasing particles and energy in the process. These decayed nuclei can be considered as "destroyed" and new atoms can be formed through nuclear reactions.
Assuming you meant atoms, no it is not. The atoms are broken into their constituent particles (IE. protons, neutrons, and electrons) but no matter is lost.
Being replaced.
Iron, being a metal does not form molecules. Being an element it consists entirely of iron atoms.
The ozone layer present in the stratospheric region of the atmosphere is being destroyed by certain chemicals. These chemicals are CFCs.
The ozone doesn't quite destroy its own molecules. Ultra-violet rays from the sun, that penetrate through the ozone break it's molecules apart. One molecule of ozone contains 3 atoms of oxygen. When the molecule splits, it releases heat. Then, one molecule of oxygen (2 atoms) and one atom of oxygen join together again, and become ozone (3 atoms of oxygen).
there constantly being hunted for their fur, there habitats are being destroyed.
yes, Ozone layer is being made and destroyed consistently. It is due to UV rays that fall on the ozone layer.

Atoms don't have wings but atoms in a gas like the air we breathe are constantly in movement, like people being knocked about in a crowd. Atoms in a liquid move a lot less and atoms in a solid hardly at all.
It is impossible to know how many cookies there are in the world. There are cookies being made and cookies being destroyed (commonly referred to as eaten) at any given moment, so the number constantly changes.
the lithosphere is the solid upper part of the mantle and the crust, which are spilt up into plates on the earth surface, which are constantly moving. at destructive plate boundaries the plates can get subducted and "recycled" into the mantle, hence lithosphere is destroyed. at mid ocean ridges new crust (lithopshere) is constantly being made. this all leads to the dynamic and continuous cycles of lithosphere being destroyed and created, hence continually changing.
trees are being destroyed by people cutting them down.
The wetlands are being destroyed because people want to build on them. The wetlands are being destroyed because people want to build on them.
Yes, stars are constantly being created and destroyed. Stars can last millions or billions of years, but there are so many of them out there that it's pretty common for them to come and go.
The rain forest is being destroyed by destruction.
The wetlands are being destroyed because people want to build on them. The wetlands are being destroyed because people want to build on them.
