The rain forest.
Planting more trees and preserving existing forests is the best way to maintain the world's oxygen supply. Trees absorb carbon dioxide and release oxygen through photosynthesis, helping to balance the oxygen and carbon dioxide levels in the atmosphere. By protecting and expanding forest areas, we can help mitigate the decrease in the world's oxygen supply.
Most of the world's oxygen is produced by phytoplankton in the ocean. These microscopic marine plants carry out photosynthesis, using sunlight to convert carbon dioxide into oxygen. Phytoplankton play a vital role in producing oxygen and supporting marine ecosystems.
Planting more trees and preserving forests would help maintain the world's oxygen supply. Trees absorb carbon dioxide and release oxygen through the process of photosynthesis, making them crucial for balancing oxygen levels in the atmosphere. Supporting reforestation efforts and reducing deforestation are key activities to sustain the oxygen supply.
The most important endothermic reaction is photosynthesis, where plants use sunlight to convert carbon dioxide and water into glucose and oxygen. This process is essential for producing oxygen, removing carbon dioxide from the atmosphere, and providing energy for plants and other organisms in the food chain.
The world's total water supply is estimated to be around 1.4 billion cubic kilometers, but only about 2.5% of this is fresh water. Of the fresh water, only a small fraction is easily accessible and clean for human use.

OIL!

Because most of the Amazon Rainforest is within its borders, and the Amazon Rainforest prduces most of the oxygen we use to breathe.

The Earth's grass produce 20 to 30 percent oxygen. The other 70 to 80 percent of oxygen is produced by marine plants.
Marine Phytoplankton. Contains over 70% of the world's oxygen.
Varies considerably depending on where you are.however the relative concentration in the amazon area is higher in the amazon area than most places on earth.Amazon Area has 50% of the CO2 to O2 conversion forests of the world and supplies 20% of the worlds oxygen.
The temperate deciduous forest is a forest in the temperate zone of the world . It contains over 66 percent of the worlds species. You can find out more about and what the temperate deciduous forest on wiki.answers.com it is simply only a click away! LOL!!
Current thinking places it at between 50 to 85 percent, depending on time of year and the state of phytoplankton bloom.
The Pine forest in Northeast Texas.
The Amazon is the worlds biggest rain forest
