It is crucial to address and mitigate the sources of air pollution to protect public health and reduce the burden of disease associated with polluted gases.

The impact of polluted gases on wildlife and plants

Respiratory and Health Issues

Wildlife experiences many similar negative health effects from air pollution as humans do. Damage to respiratory systems is the most common issue, but neurological problems and skin irritations are also frequently observed. For instance, high levels of ground-level ozone can induce muscle contractions in the lungs, making breathing difficult. Long-term exposure can lead to lung inflammation and permanent lung damage in both animals and humans.

Impaired Growth and Development

Plants and crops are particularly vulnerable to the effects of polluted gases. Ozone pollution, for example, harms plants by damaging stomata, tiny pores on the underside of leaves that allow plants to breathe. This reduces their growth rates and makes them more susceptible to pests and diseases. From 1980 to 2011, the United States lost $9 billion worth of soybeans and corn due to ozone pollution. Additionally, acid rain, lead toxicity, and exposure to nitrogen oxides change the chemical nature of the soil, robbing plants of essential nutrients and impairing their growth and survival.

Disruption of Ecosystems

Polluted gases can also damage the habitats, water sources, and food sources that plants and animals rely on. Ecosystems are changing faster than plants and animals can adapt, leading to species extinction. For instance, marine ecosystems are vulnerable to ocean acidification caused by carbon dioxide emissions, which makes it difficult for marine species to grow shells and skeletons. The decline of even a few species due to air pollution can topple the delicate balance of entire ecosystems.

Impact on Biodiversity

Air pollution reduces biodiversity by damaging vegetation and crops. Ground-level ozone, in particular, affects agricultural crops, forests, and plants by reducing growth rates, lowering yields, and impacting biodiversity and ecosystem services. In 2019, economic losses due to the impacts of ground-level ozone on wheat yields amounted to €1.418 billion across 35 European countries.

Climate Change

Polluted gases, especially greenhouse gases, contribute to climate change. The burning of fossil fuels, deforestation, and agricultural practices release carbon dioxide, methane, and nitrous oxide into the atmosphere, leading to an enhanced greenhouse effect and global warming. This, in turn, affects wildlife and plants by causing more frequent and intense extreme weather events, altering precipitation patterns, and raising sea levels.

Overall, the impact of polluted gases on wildlife and plants is extensive and has far-reaching consequences for the health and survival of various species, including humans. Addressing these issues requires a combination of global efforts to reduce greenhouse gas emissions and mitigate climate change, as well as local actions to protect and restore affected ecosystems.
