Plants take water and use it in photosynthesis to produce energy. Oxygen is produced from the processing of H2O (Water). Does this mean that the world's oxygen is produced from water?

About 80% of the world's oxygen is produced by the humble alga, believe it or not.

Plants produce sugars from Carbon Dioxide and water. At the same time oxygen is evolved as shown below:
6CO2 + 12H2O------ C6H12O6 +6CO2 + 6H2O
Water appears on both sides of this equation because it has been shown that all the oxygen evolved originates from the water.
The oxygen atoms in the glucose and water molecules on the right-hand side of the equation are those which are originally combined with carbon in the carbon dioxide.
The equation is relatively simple but it shows only the starting materials and final products of a series of complex reactions
It seems that you are right - all oxygen is produced from water.

Well, to think in a nutshell...yes, your statement makes pure scientific sense. However, you missed out on two important parts of the photosynthesis process - Carbon Dioxide and Light from the Sun. For further details: read -
http://en.wikipedia.org/wiki/Photosynthesis
So, this means global warming is in a very big part connected to human activity. How so?? easy :
Humans burn fossil fuels that produce greenhouse gases (Carbon Dioxide plays a huge part in this), with our daily activities (example: lighting up at home, playing video games, powering the computer[yes, I admit that i use a computer that contributes to carbon emissions - but hopefully I get to use it for the benefit of educating people about global warming], driving the car, traveling, etc).
Furthermore, we chop down trees and forests that help turn carbon dioxide into oxygen. We pollute the air with smoke/smog, limiting sunlight from helping out the photosynthesis process. That being said, we are our own fools if we continue on with our lives being ignorant about the issue of Global Warming and Climate Change.

No, oxygen comes from a lot of nature process not just by photosynthesis alone. Chemical reactions in the ozone can break the molecules to oxygen you see and that's only one of thousand phenomenon

I believe you are correct.
