No, normal human senses cannot detect an oxygen-enriched atmosphere, as our senses do not have the ability to directly detect or measure the percentage of oxygen in the air. Specialized equipment is needed to accurately measure the oxygen content in an atmosphere.
Deforestation would interfere most directly with the production of oxygen in the environment by reducing the number of trees available to photosynthesize and release oxygen into the atmosphere.
The lungs take in oxygen directly from the air.
Our bodies utilize oxygen from the atmosphere.
The balance of oxygen and carbon dioxide is maintained in the atmosphere by the oxygen released by plant during photosynthesis and carbon dioxide released by human ,animal's etc in the atmosphere

The lungs are the part of the human body that absorbs oxygen directly from the air. When you breathe, the lungs take in oxygen from the air and transfer it to the bloodstream to be transported to cells throughout the body.
The composition of a planet's atmosphere, including the presence of oxygen, is crucial for human respiration. Depending on the composition, a thick atmosphere might not contain enough oxygen for human survival, making it impossible to breathe. Additionally, other gases or compounds in the atmosphere can be harmful or toxic to humans.
protect the earth and havee oxygen to human breath
Oxygen is the most essential element in Earth's atmosphere for human life. It is needed for cellular respiration, the process by which our cells generate energy. Without oxygen, humans would not be able to survive.
