Speculate the probable causes of each of the following phenomena: Insomnia, High blood pressure, partial or complete deafness Decrease in the concentration of dissolved oxygen in water and floating of dead fishes Dwindling populations of alligators were the result of hunting and loss of habitat, Inflammation in the respiratory tract of lung Decrease in the number of pollination insects

Air pollution refers to the release of pollutants into the air—pollutants which are detrimental to human health and the planet as a whole. According to the World Health Organization (WHO), each year air pollution is responsible for nearly seven million deaths around the globe. Causes of Insomnia, High blood pressure, partial or complete deafness: Air pollution is a cause of such diseases. Hypertension is an accelerating factor in the degeneration of the auditory system and hearing as people age. Low dissolved oxygen primarily results from excessive algae growth caused by high levels of nutrients such as phosphorus and nitrogen. This is known as water eutrophication (nutrient enrichment) resulting from anthropogenic activities such as agriculture, industry, and sewage disposal. Dwindling populations of alligators and crocodiles were the result of hunting and loss of habitat. Lung inflammation can come from exposures, infections, and diseases like asthma or bronchitis. When airborne toxins enter the lungs, irritation results. Common irritants include: Cigarette smoke, Pollutants, Chemicals, Fumes. The main problem affecting most pollinators is thought to be the loss of suitable habitat. Including forage and nesting or breeding sites.
