Carbon is found in the atmosphere mostly as carbon dioxide.
Darwin lived in a time where natural selection was a strange theory among scientists and researchers. This was especially true when other researcher Lamarck argued that organisms passed on helpful traits to their offspring, that they magically could form a new trait to adapt to their environment and then pass it onto their offspring. For example, if a giraffe was too short to reach food, it would grow a larger neck in its lifetime and then pass that trait onto its offspring. Darwin argued that, through the process of survival of the fittest, that short giraffe would die off and never receive the chance to pass on its shortness to future populations. Thus, taller giraffes would survive— they can reach food, shorter giraffes can’t— and the short genes would disappear. The fact that Darwin was introducing a new theory that nobody was used to at the time was peculiar, so he had few people on his side until long after his observations.
Another problem Darwin had was the lack of technology. To travel, Darwin would have to use boats to reach far away places, and of course, this took time.
The final problem Darwin had was the extra time it took for evolution, a process that can take up to millions of years. Evolution didn’t occur over night— it took time for Darwin to conduct experiments, observe, conduct them again, come to a conclusion, and so on.

Explanation:
Sulfur dioxide and nitrogenous oxide released from industries and power plants infiltrate river ways by acidic rainfall. Sewerage and effluent are released into rivers in some regions. Pollution can decrease the pH of the water, attacking all organisms from algae to vertebrates. Biodiversity reduces with reducing pH.
Well, the technical rule of thumb would be that if it is raw, it has about a good 2-3 days before it goes bad. If it's cooked, it has about 3-4 days before it spoils. If they are leftovers, you have, at the latest, a total of 4 days before they aren't "safe" to eat anymore. Hope this helps!
