Natural Oxygen is necessary, it has to be saved at all costs from pollution..
- What is Oxygen?
Oxygen is a chemical element with an atomic number of 8 (it has 8 protons in its nucleus). Oxygen forms a chemical compound (O2) of two atoms which is a colorless gas at normal temperatures and pressures.
Oxygen atoms are very reactive and are incorporated into many common chemical compounds, such as water (H2O), carbon dioxide (CO2), carbon monoxide (CO), sulfur oxides (SO2 and SO3, and nitrogen oxides (NO and NO2).
About 21% of Earth’s atmosphere is oxygen. This has not always been the case, though. Early in our planet’s history, the atmosphere had almost no oxygen. Microbes that produce their food via photosynthesis generate oxygen as a by-product. Oxygen from photosynthetic microbes eventually built up in the atmosphere, drastically changing our planet’s environment and the history of life in the process.
Oxygen plays a critical role in respiration, the energy-producing chemistry that drives the metabolisms of most living things. We humans, along with many other creatures, need oxygen in the air we breathe to stay alive. Oxygen is generated during photosynthesis by plants and many types of microbes. Plants both use oxygen (during respiration) and produce it (via photosynthesis).
Oxygen can also form a molecule of three atoms, which is known as ozone (O3). Ozone in Earth’s stratosphere plays a helpful role by blocking most of the harmful UV radiation from the Sun, while ozone in the troposphere is a hazardous pollutant.
2. How to save it?
Ten Simple Things You Can Do to Help Protect the Earth
- Reduce, reuse, and recycle. Cut down on what you throw away. Follow the three “R’s” to conserve natural resources and landfill space.
- Volunteer. Volunteer for cleanups in your community. You can get involved in protecting your watershed, too.
- Educate. When you further your own education, you can help others understand the importance and value of our natural resources.
- Conserve water. The less water you use, the less runoff and wastewater that eventually end up in the ocean.
- Choose sustainable. Learn how to? form free resources.
- Shop wisely. Buy less plastic and bring a reusable shopping bag.
- Use long-lasting light bulbs. Energy-efficient light bulbs reduce greenhouse gas emissions. Also, flip the light switch off when you leave the room!
- Plant a tree. Trees provide food and oxygen. They help save energy, clean the air, and help combat climate change.
- Don’t send chemicals into our waterways. Choose non-toxic chemicals in the home and office.
- Bike more. Drive less.
