A waste product of photosynthesis organisms need for cellular respiration is oxygen. We breathe out carbon dioxide and plants use carbon dioxide during photosynthesis and in return they give us oxygen which is their waste product.
Tons of rain can cause an ecosystem to flood, killing species that are not meant to withstand lots of water. Ocean temperature can slow down or speed up evaporation, affecting precipitation rates.

<span>The labs were unable to reproduce the pharmaceutical company’s data
An important characteristic of scientific experiments is that their results can be replicated. In this case, assuming that the laboratories followed the same procedure as the pharmaceutical company, the fact that the data could not be replicated means that the company's claims are invalid. The validity of the claims is more questionable given the huge difference in the final conclusions, with the company reporting a 35% decrease, while the maximum decrease observed by the labs was 8%.
