In the Fall of 2010, we had many Alside window sets put in. When Spring came, we opened all but four of the windows 1/4 to 1/2 way. We never fully closed and locked the windows until late July/early August when the hurricane was due to come up the east coast.

Early bacterial life introduced oxygen to the atmosphere. As the first free oxygen was released through photosynthesis by cyanobacteria, it was initially soaked up by iron dissolved in the oceans and formed red coloured iron oxide, which settled to the ocean floor.arly life affected the structure of the planet. Presenter Aubrey Manning and geologist Professor Maarten De Wit investigate iron rich rocks known as banded iron formations, which formed when stromatolites, some of the earliest known life forms on Earth, produced oxygen that combined with iron dissolved in the oceans.
