Oceans produce approximately 80 percent of the oxygen our planet needs to support animal life. pollution that reaches the ocean through dumping, oil leaks, runoff, and other processes interferes with that oxygen production and poses a real threat to the oxygen content in our atmosphere. if the oxygen content decreases, it is likely that carbon dioxide will increase. this could have dramatic consequences for life as we know it. which does this passage indicate causes a decrease of oxygen in the atmosphere?

Pollution in the oceans

Explanation:

This passage is simply describing the effect that the pollution of the ocean waters had on the composition of the atmosphere. It is a fact that the pollution of the ocean waters i enormous, and unfortunately the oceans became the ''sewage'' of the human kind.
