Since the beginning of civilization, there has always been this question, “Where are we going to put all of our waste?” Well before the late 1800; garbage, which consisted of spoiled food, broken items, and sewage, was simply thrown on to the street. The issue was that such habits gave rise to diseases and had numerous sanitation problems, thus garbage-men were born. They transported the trash on the streets to be burned, buried, or dumped into the ocean. Today, we have landfills for our garbage. Now a properly managed dump can be a very safe, almost cleanly area.
Abstract This study focussed on the waste pickers from the Free-State region and the impact of their activities on the environment. I also focussed on the factors that influence successful waste picking, such as weather conditions and proper storage areas. This study indicates that male waste pickers usually have a greater income than female waste pickers. Reasoning for this is, in most cases the waste that is collected requires a lot of muscle strength and the distances between the Buy Back Centre and the collection site is quite far. These conditions are not in the favour of the ladies.
These form of pollutants are more often removed from the communities by local municipal authorities. The reason for which it is named waste water is because of the presence of 99 % water in its composition. The remaining segments of these materials include: bacteria, human waste, detergents, soaps and other related chemicals. In Kuwait, due to the lack of proper sewage management and control measures is the reason for which most of these waste materials are returning to the environment. The developed regions of the world make use of numerous state of the art wastewater management and processing plants.
Nitrogen dioxide is another pollutant which is a fuel combustion as a result of electric utilities, vehicles, and wood burning. Sulpur dioxide which is another heavy pollutant comes from fuel combustion of electric utilities, industries, and the natural phenomenon such as volcanoes. An additional air pollutant in Cameroon is particulate matter which comes as a result of chemical reaction via fuel combustion such as the burning of wood, farming, forest burning, construction
 Natural sources of air pollution • An example of natural air pollution can be found from the smoking hills found in the wilderness of the Canadian Arctic. The local environment around the smoking hills is virtually uninfluenced by humans. It occurs naturally due to low-grade coal deposits found in the area have spontaneously ignited from time to time, causing the release of clouds of sulphur dioxide over the nearby tundra. Those gasses are carried to the surface, soil and freshwater, and they become acified. • When a volcano erupts it releases gasses like sulphur dioxide and carbon monoxide, and also releases solid material and all those are dangerous to the human health to an extent that mortality can occur and also plants and animals can be harmed by the substances and solid materials.
In different beaches around the world there is a problem with sand erosion. Sand erosion is the wearing away of land and the removal of beach or sand dunes sediments by water. Although the building of the structures in Monaco isn 't creating sand erosion directly it is still making sand erosion a bigger problem. The way that Monaco are building these structures on the ocean there is a lot of sand involved. After they have built the foundation they fill the sea trapped inside with various rocks and sand shipped from the beaches of Sicily.
Pollution emitting from vehicles including cars, trucks, jeeps, airplanes and trains cause huge amount of pollution. Although we rely on them for our daily lives they kill our environment with dangerous gases, Carbon Mono-oxide caused by irregular combustion and produced from vehicles and other major pollutant like Nitrogen Oxides, that is produced by both natural and man-built
Another reason contributing to this could’ve been the heavy commercial vehicles passing through the city which are responsible for most of city’s pollution due to vehicles (46%). The Delhi government hadn’t completely banned their movement through the city, the commercial vehicles could enter the city in the night time till early morning. It was also found later that the emissions from two wheelers was responsible for 33% of the total vehicular pollution, even more than petrol cars. Exemption of these made the policy less effective. A large part of three-wheelers also contributed to this which were running on kerosene.
get mixed in water and if the toxic elements are in large quantity then optimal concentration then it will pollute water. 1.3.6. Thermal sources of water pollution: Thermal pollution is generated by power plants. Industrial sources such as pulp and paper mills, petroleum refineries, chemical plants. Warm water from these industries domestic areas directly discharged into the rivers, lakes and other water bodies.
