Air pollution is the present of contaminated in the atmosphere with the potentials of causing adverse effects to human and it environment. It comes from natural sources such as volcanic eruption, wind blown dust and anthropogenic source such as fossil fuels combustion, Bush burning, industrial activity, waste treatment processes, livestock cultivation just to name a few. Examples of some of these pollutants include; methane, hydrochlorofluorocarbons, chlorofluorocarbon, carbon dioxide, nitrous oxides, ozone, water vapor, particulate matters, aerosols just to name a few. The greenhouse gases have the highest potential of causing harm as there are the driving forces behind the much talk about climate change which is as a result of an increasing global temperature.
Livestock farming is one of that sector that is often neglected when talking about potential sources of air pollution. The rising demand for food, especially form livestock production, has elicited great concerns over their negative environmental impacts. In different parts of the world, animal production is highly concentrated and is expanding rapidly. Not only are there more animals in the farms, but the farms themselves are becoming more specialized, consequently increasing their environmental load which doesn't exclude air contamination. Aerial pollutants generated by the animal farms affect the quality of the local atmospheric air, the neighborhood, and the health of both animals and workers. The concentrations of air pollutants are influenced by the design of the housing systems and their ventilation rate, as well as animal waste management practices. Housing systems are a very common feature in concentrated and intensive livestock cultivation such as piggery and poultry farming. In order to limited the local atmospheric pollution, it is important for farmers to take into consideration the installation air filters such as; biofilters, air scrubbers, electrostatic precipitators, settling chambers and odour control systems when setting up a farm. The manner in which the animal waste is being managed should be taken into account due to it potential of releasing greenhouse gases into the atmosphere. The production of heat, electricity, biogas from this will not only reduce the amount of greenhouse gases released into the atmosphere but will limit the dependence on non renewable energy sources, controls odour, product of high quality compost fertilizer and will also act as a great source of income.

Hello Sandrine! This is your mentor Yewon.
I apologize for the late comment.
You have written a wonderful report about air pollution from livestock farming.
I have heard that livestock farming has large negative impact on air quality, but I didn't know the exact information about that. Thank you for sharing, I could learn a lot from your report:D
Thank you for your meaningful report! Great job!

Hello Sandrine! This is your mentor James!
I see that you have described the background information regarding air pollution in detail, and then illustrated the connection between air pollution and livestock farming! Along with increasing population, food resources are becoming more scarce. When it comes to meat and dairy products, its supply is always insufficient for the whole population. Thus, livestock farms are increasing as well to match the demand, which is leading to the greenhouse gas emission as you've mentioned above.
Thanks again for this meaningful report! Hoping to read your next writing as well!
