Urban Gardening is a fairly new idea that is countering the mindset that food should be grown in rural areas only. Not only does urban gardening help you with lower food prices and creates more green space in an urban area but it also helps produce more oxygen in a urban area. Along with urban trees, urban gardens create their own food from the carbon dioxide from the water, soil, sunlight, and atmosphere. During which the release oxygen to which we breathe. Not only do they produce oxygen but they also trap and hold pollutants and dangerous gasses such as ash, dust, smoke, pollen, and carbon dioxide while they produce oxygen. This helps prevent “dead zones” which is an ecology term for low oxygen areas off the world’s oceans and larger lakes of the world caused by pollution to water. Which affects the overall health of the city because you need oxygen to breathe. By increasing urban trees, gardening, and overall green space within a high-density population you can produce enough oxygen to accommodate for the high population. You can even improve the air quality within your own home by adding plants to you living room, dining room, or even bedroom. This way you can produce fresh oxygen within your own home. Consuming plentiful amount oxygen will help you avoid medical symptoms caused by oxygen deficiency stomach acid, bacterial, viral, parasitic infection, chronic hostility, circulatory problems, increased proneness to common infections such as the flu, fatigue, dizziness, bodily weakness, poor digestion, and irrational behavior. Urban gardening and urban trees are essential to a city’s health because of the high demand for oxygen with limited areas for green spaces.
