Earth's Oxygen cycle
Earth has a high concentration of oxygen gas.
The reason is the oxygen cycle:
Three main oxygen reservoirs on Earth
Life on Earth needs balanced biochem-levels
Do you know why there is oxygen on Earth?|
Photosynthesis is the main driving factor. Without photosynthesis Earth's atmosphere would be very different - not supporting life as we know it. Photosynthesis produces oxygen which rises into the atmosphere. Respiration, chemical reactions as decay remove oxygen from the atmosphere
Oxygen = chemically OOxygen got its name from the Greeks, a long time ago.
Oxygen is highly reactive
Oxygen can form compounds with almost all other elements. Chemists call them oxides.|
When we look at all the masses in our universe, oxygen is the third most abundant element, following hydrogen and helium. By mass Oxygen is the most abundant element in the Earth's crust.
Earth's air contains 20.8 percent diatomic oxygen
Without oxygen proteins, carbohydrates, and fats, bones, teeth, animal shells, would not exist - imagine us without all that... Humans would not exist.
Life on Earth started in Earth's oceans, when cyanobacteria produced O2 Oxygen. Later, algae, green plants and trees produced oxygen with photosynthesis
All cells use oxygen in their cellular respiration.
The onion-like layers of a massive star
Oxygen is part of every star
All elements of a star:
H = Hydrogen
He = Helium
C = Carbon
Ne = Neon
O = Oxygen
Si = Silicon
Fe = Iron
Most of all living organisms contain + need oxygen
Imagine life without amino acids, without neurotransmitters or alkaloids. Life on Earth would be very different!
Humans, of course, need oxygen.
We breath in oxygen O
We breath out carbon dioxide CO2
And we are healthier and happier when
there are not too many pollutants in the air!
Life on Earth depends on a good balance - some human decisions unbalance Nature, endangering all life on Earth!
Bear Springs Blossom Nature Conservation Group's mission is to fight for a safer future of our children and grand children.
NASA scientist Hansen's statement:
"I decided that I didn't want my grand-children to say, 'grandpa understood what was happening but he didn't make it clear, he didn't act .."
This is exactly our motivation and the motivation of BSB members.|
Members of BSB show responsibility and state clearly:
We recognize the problem and we DO as much as we can to lower the impact on our children's life!
