The oxygen in the upper atmosphere combine to form ozone layer (o3) that allows to colonize surface water.
Explanation:
The fossil stomatolites are formed at about 3.0 ga laminated bacteria. they form the sediments to fall into a thin film of bacteria, these bacteria binds with the sediment and grows through it.
Cynobacteria uses water, CO2 and sunlight to create their own food and produce oxygen as a by product. The significance of stromatolites is that they are earliest fossil evidence life on earth.
They were first organism to photosynthesis and produce oxygen.
It can affect the environment because it could absorb into the ground and contaminate the groundwater, then this could runoff into a pond, river, lake, etc., which would then contaminate that water source. This also negatively impacts wildlife because they rely on these water sources to drink water, bathe, and/or catch food (ex: a bear catching a fish in a river).
