Given in no particular order:
Carbon dioxide is increasing in the atmosphere today primarily due to human activities such as burning fossil fuels, deforestation, and industrial processes. These activities release large amounts of carbon dioxide into the air, leading to higher concentrations in the atmosphere.
The carbon cycle is vulnerable today due to human activities such as burning fossil fuels and deforestation, which are releasing more carbon dioxide into the atmosphere than natural processes can remove. This imbalance is leading to an increase in atmospheric carbon dioxide levels, contributing to climate change and disrupting the delicate balance of the carbon cycle.
Nitrogen has, since plants and animals have existed, been the majority of gases in our atmosphere. Carbon Dioxide; however, has been increasing in our atmosphere since the industrial revolution. The causes are automobiles, coal-burning power plants and other carbon-emitting activities.
Carbon dioxide is 30% more prevalent in Earth's atmosphere today than it was before the Industrial Revolution. This increase is primarily due to human activities such as burning fossil fuels and deforestation. Carbon dioxide is a greenhouse gas that contributes to global warming and climate change.
The original atmosphere contained only nitrogen, carbon monoxide, carbon dioxide, methane, and water vapor. Today's atmosphere contains 78% nitrogen, 21% oxygen, 1% shared between argon, carbon dioxide, helium, methane, ammonia, and neon.
We are adding more and more carbon dioxide to the atmosphere. This is causing global warming and climate change.

The present levels of carbon dioxide dioxide in the atmosphere are causing global warming and climate change.
carbon dioxide
Ancient photosynthetic bacteria transformed the carbon dioxide atmosphere into oxygen through the process of photosynthesis. Over billions of years, these organisms released oxygen as a byproduct, eventually leading to the oxygen-rich atmosphere we have today that you breathe.
Today the average concentration of carbon dioxide in the atmosphere is approx. 4oo vpm; some scientists consider that values over 300 ppm are high.
As opposed to today's atmosphere, the Earth's early atmosphere would have been quite impossible for human life to thrive in. Today the atmosphere consists primarily of Nitrogen, Oxygen, and Carbon Dioxide, but early Earth's first atmosphere was probably made of Hydrogen and Helium.

The most of the oxygen in the Earth's atmosphere today comes from photosynthesis by plants and other photosynthetic organisms. They convert carbon dioxide into oxygen as a byproduct, which accounts for approximately 20.95% of the atmosphere.

Yes, before photosynthesis evolved, oxygen was rare in Earth's atmosphere. Early Earth's atmosphere was composed mainly of carbon dioxide, nitrogen, and water vapor. As photosynthesis evolved and became more widespread, oxygen began to accumulate in the atmosphere, leading to the oxygen-rich environment we have today.
