Let us assume that mankind genetically-engineered a microorganism which can photosynthesize using the following chemical reaction:
2N2 + 6H2O -> 4NH3 + 3O2.
Then, this microorganism is released into the Earth's oceans and after a period of time, it spread to the entire Earth.
- How would the ecosphere/biosphere get affected?
- How would the global climate & atmosphere get affected?
- What would generally happen to the Earth?
- After a long period of time, how would living things adapt to the changes?
