How animals adapt to air pollution

Air pollution is a common phenomenon mostly in third world countries like Kenya. With factory emissions taking the lead, use of firewood for cooking is also a major contributor. Over 80% of the rural population use firewood for cooking. This puts the plants, animals, humans and in extreme cases buildings to higher risks which are in most cases visible even to the naked eye. Notably, the magnitude of pollution, extent and duration of exposure to such kinds of pollution determine whether a population can  survive in short-term, succumb or even evolve in long term.

Fortunately or unfortunately, humans and animals  have overtime learnt to adapt to the various forms of air pollution. After all it is something within their environment so they have to live with it.

Studies show that some animals adapt through a change in their genes  that is, adaptation through evolution. I know you have heard of the evolution of moths during the industrial revolution in 1800s when the heavily polluted regions in Britain  had walls turn black with soot. The originally peppered moth through mutation turned black making it hard for predators to spot them hence surviving to breed more unlike the peppered moths.

In lakes, the Killifish has also proved to survive extremely toxic water pollution (which can also result from air pollution) in the eastern rivers.

 However, despite such animals evolving to survive, it is worth noting that the organisms that survive through evolution brought about by any form of pollution whether anthropogenic or natural, are different from their ancestors who evolved without influence of pollution. Animals which evolve also pass their genes to their next generation hence ease in survival of such next generations.

In conclusion, although animals are finding ways to adapt to polluted environments, we have an obligation to do away with the unnecessary air pollutants and also maintain the controllable  air pollutants at bearable levels which would see the adverse effects in animals reduced.
