Carbon dioxide other greenhouse gases in the air causes an increase of people with respiratory issues. [29] There is a common relationship between air pollution and population. Africa widely diverse between areas that are overpopulated versus areas that are scarcely populated.
Aquaculture allows for fish to be farmed for production and provide more jobs for the local people of Nigeria. Overfishing is not the only impact on marine communities. Climate change, habitat loss, and pollution are all added pressures to these important ecosystems. The banks of the Niger River are desirable and ideal locations for people to ...
Animal agriculture is a cause of harmful particulate matter pollution in the atmosphere. This type of production chain produces byproducts; endotoxin, hydrogen sulfide, ammonia, and particulate matter (PM), such as dust, [61] [62] all of which can negatively impact human respiratory health. [63]
The air pollution in downtown Cairo is more than 10 to 100 times of acceptable world standards. [8] Cairo has a poor factor because of lack of rain and its layout of tall buildings and narrow streets, which create a bowl effect (bad ventilation and consequent trapping of pollutants). The main air pollution problem in Egypt is particulate matter.
If oxygen depletion progresses to hypoxia, fish kills can occur and invertebrates like worms and clams on the bottom may be killed as well. Still frame from an underwater video of the sea floor. The floor is covered with crabs, fish, and clams apparently dead or dying from oxygen depletion. Hypoxia may also occur in the absence of pollutants.
Air pollution can cause diseases, allergies, and even death; it can also cause harm to animals and crops and damage the natural environment (for example, climate change, ozone depletion or habitat degradation) or built environment (for example, acid rain). [3] Air pollution can occur naturally or be caused by human activities. [4]
This form of pollution can lead to many problems. One is the degradation of aquatic ecosystems. Another is spreading water-borne diseases when people use polluted water for drinking or irrigation. [155] Water pollution also reduces the ecosystem services such as drinking water provided by the water resource.
Diseases caused by pollution, lead to the chronic illness and deaths of about 8.4 million people each year. However, pollution receives a fraction of the interest from the global community. [1] This is in part because pollution causes so many diseases that it is often difficult to draw a straight line between cause and effect.
