Living in city has the number of drawbacks
pollution
air pollution
increased risk of heart attack, wheezing, coughing, and breathing problems, and irritation of the eyes, nose, and throat
Acid rain contains high levels of nitric and sulfuric acids that are created by oxides and sulfur oxides released into the air by the burning of fossil fuels
Nitrogen oxides released into the air by the burning of fossil fuels also contribute to the nitrogen responsible for toxic algae blooms.
The release of man-made compounds including hydrochlorofluorocarbons, chlorofluorocarbons, and halons formerly used as coolants, foaming agents, pesticides, solvents, aerosol propellants, and fire-extinguishers are depleting the ozone
water pollution
Bodies of water that are near urbanized areas tend to be heavily polluted by dumbing of garbage and chemicals, both legally and illegally, by industrial plants, health centers, and individuals.
Pollutants such as cadmium, mercury, and lead are eaten by tiny aquatic organisms that are then eaten by fish and shell fish, becoming more concentrated with each step up the food chain and causing serious problems in humans and wildlife.
Nutrient pollution can cause toxic algal blooms in drinking water sources that create toxins that kill fish and other aquatic animals. Direct exposure to this toxic alga causes serious health problems in humans including neurological effects, respiratory problems, stomach and liver illness, and rashes
disinfectants used to treat drinking water reach water polluted with toxic algae, they react creating dioxins. Dioxins are extremely harmful chemical compounds that have been linked with reproductive and development problems, and even cancer.
land and soil pollution
has substantial consequences for humans, animals, microorganisms and aquatic life. Contaminated land and soil can cause various problems on the skin, respiratory problems, and even different kinds of cancers.
These toxic substances come into contact with the human body directly through eating fruits and vegetables that have been grown in polluted soils, being consumed through drinking water that has been contaminated, direct contact with the skin, and breathing in air polluted with particles and dust.
Clear cutting of vegetation and tree cover creates harsh conditions that destroy ecosystems and habitats.
creates an imbalance in atmospheric conditions, reducing the amount of carbon that is naturally taken out of the atmosphere
noise and light pollution
cause stress, anxiety, headaches, irritability, hearing loss, and sleep loss resulting in decreased productivity
Oil drills, submarines, and other vessels on and in the ocean can cause excessive noise that has resulted in the injury or death of marine animals, especially whales.
Too much light causes eye strain and stress, harming our eyes and decreasing our quality of life
Light pollution also causes a decrease in the hormone melatonin that helps us to fall asleep, resulting in restlessness and fatigue
giving rise to higher rate of homelessness
High cost of living
at a higher risk of stress, depression, anxiety disoders
housing crisis
high poverty rates
High unemployment rate
over crowding
traffic jams
lack of sufficent housing
increased physical contact, lack of sleep, lack of privacy and poor hygiene practices
