The growth of mega cities in developing countries is affected by issues such as high population, an ever increasing need to expand in order to accommodate this population bulge and unequal access to basic public services among the different social classes. Urbanization of this trend has an adverse effect on the environment due to lack of sanitation, excessive waste, various forms of pollution (air, water and soil) and lack of proper waste treatment methods.
In my individual work I studied the provided material that focuses at discussing types of waste, waste-related problems in cities and waste treatment techniques. After I grasped the main content of the material, I reflected my gross ideas as below:
Waste is produced almost everywhere. Homes, industries and farming produce wastes of different type and varying proportion. What makes it difficult for cities to manage waste is due to a number of reasons such as rapid population growth, poor city planning which stems from bad governance, improper waste dumping process (such as mixing of toxic and domestic wastes), lack of knowledge among the local community concerning waste management and reluctance on the side of the government to promote the virtues of proper waste management.
There are a number of waste treatment methods that can be applied depending on the type of waste. Some of the techniques, however, are rather controversial. One example is taking the waste to landfills, as it results in the release of methane in to the atmosphere and also it consumes a lot of land space.
For waste management to function correctly - it is important to educate the society to increase awareness, laws not only need to be passed but also need to be implemented and there must be a social welfare.
