Bad ozone , near ground level the pollutants emitted by cars, refineries etc react in the presence of sunlight. these are very harmfull . they get in bodies while breathing hope u understand . plzz upvote and follow.

What is Bad Ozone?
Bad ozone, often referred to as ground-level ozone, is a harmful air pollutant that affects both human health and the environment. Unlike the protective ozone layer in the stratosphere, which shields the Earth from harmful ultraviolet radiation, ground-level ozone is a byproduct of chemical reactions between volatile organic compounds (VOCs) and nitrogen oxides (NOx) in the presence of sunlight.
Health Impacts
- Ground-level ozone can cause respiratory problems, including asthma and bronchitis.
- It can aggravate existing lung diseases and reduce lung function.
- Prolonged exposure can lead to increased hospital admissions and premature deaths.
Environmental Effects
- Bad ozone adversely affects ecosystems, including forests, crops, and wildlife.
- It can damage plant leaves, reducing photosynthesis and crop yields.
- Sensitive ecosystems, like wetlands and grasslands, may experience disruptions in their natural processes.
Role in the Food Chain
- The impact of bad ozone on plants can have cascading effects on the food chain.
- Decreased plant health results in less food available for herbivores.
- This reduction in food availability can affect predators and entire food webs, leading to biodiversity loss.
Mitigation Strategies
- Reducing emissions from vehicles and industrial sources can help lower ground-level ozone levels.
- Promoting public transportation and using cleaner energy sources are effective approaches.
- Raising awareness about the sources and effects of bad ozone can lead to community actions that improve air quality.
In summary, bad ozone poses a significant threat to human health and the environment, necessitating collective efforts to mitigate its effects and protect ecosystems and food chains.
