In fact, direct exposure can lead to diseases through chemical exposure as the release of chemical waste into the environment leads to chemical poisoning. Air pollution The pollution of the air is represented by the release of harmful chemicals and particulates into the atmosphere that are affecting the human health and the environment. People and animals that live close to: a factory, a commercial center, a railroad, a highway, an airport etc. In particular, plastic pollution has been on the rise in the first decade of this century due to rapid urbanization and population growth and most of the used plastic materials simply end up in the landfills. Moderate grazing can increase species diversity by opening up the community and creating more niches.
Many of them were on the endangered species list. Through the 19th century, water and air pollution and the accumulation of solid wastes were largely problems of congested urban areas. Getting rid of your trash in an environmentally sustainable way is one of the best things we can do for the earth! Thermal Pollution and Biodiversity One of the very important water pollution facts is that thermal pollution is a growing problem. A Plasma Power Plant can also utilise existing landfill content as a feedstock, thus cleaning up previously toxic sites and enabling them to be sold for other uses such as development. This approach is of growing interest to the major European energy providers, who must boost their renewable electricity output 15%-20% to meet the targets. Industrial Wastes : Industrial wastes are released from chemical plants, paint industries, cement factories, power plants, metallurgical plants, mining operations, textile industries, food processing industries petroleum industries and thermal power plants. When these wastes are in excess they act as pollutants and are not easily decomposed and they take much time for their decomposition.
The natural aquatic food chain goes like this: Algae and Phytoplankton consume carbon dioxide, inorganic nitrogen and phosphate from water as food They serve as food for Zooplankton Small fish feed on Zooplankton Small fish are consumed by large fish When nutrients become abundant due to waste accumulation,the growth of phytoplankton and algae increases, and consequently the penetration of oxygen, light and heat into the water body is reduced. Impact of Waste Accumulation on Aquatic Life Freshwater and Marine : Solid and liquid wastes that accumulate in water bodies affect the physical, chemical and biological characteristics of the aquatic ecosystem. They can cause cancer, developmental defects and reproduction problems. In brief, the process of dealing with waste is called as waste management. Remember, much of our stuff these days is made with chemicals. The harmful gases and substances released into the environment are causing in some cases, changes in the natural habitat that are affecting the local flora and fauna. Unattended waste lying around attracts flies, rats, and other creatures that in turn spread disease.
It is not something that we just put in a corner or secured area and work around. Similarly, old newspapers make great packaging material. A fact that is important here is the spoilage of soil by waste accumulation which can no more support tree species for a regeneration of forest as a climatic climax community. Pollution of drinking water, 3. We can see piles and piles of garbage everywhere around us. Other sources of radioactive wastes are from mining of radioactive substances and atomic explosion etc.
The dumping of solid wastes is hazardous to human health. With increase in the global population and the rising demand for food and other essentials, there has been a rise in the amount of waste being generated daily by each household. Also, this will set as an example for your friends, family and relatives and they will also start buying items made from recycled products. Any living organism relies on water to survive. Industrial waste from factories and plants is another issue. Over 46% of lakes are too polluted, the same as the rivers. The substances that pollute are called pollutants and they are either foreign substances or energies, or even naturally occurring contaminants.
Methane is a strong greenhouse gas and contributes to. Coloured plastics are harmful as their pigment contains highly toxic metals, such as copper, lead, cobalt, chromium and cadmium. Besides the chemicals from household and industrial products, electronic wastes contain lead, mercury and cadmium. Burning of coal,petroleum or fuel wood produce sulphur and nitrogen which react with oxygen to form their respective oxides. Of the animals that were affected that are still alive, only 6% have been cleaned. Prevention of Water Pollution The effects might seem irreversible, but they are not.
Some methods of waste disposal release air pollutants and greenhouse gases into the atmosphere. The solid wastes like the animal manure and other agricultural by products are collected and dumped in the landfills. Research reveals that 82% of landfills have leaks. Reuse old shopping bags and containers for maximum efficiency, and better yet, cloth bags. With improper sewage systems, sewage will often be dumped into rivers, as a means of disposal. Oil does not dissolve in water and forms a thick sludge. Moreover, many lightweight, single-use plastic products and packaging materials, which account for approximately 50 percent of all plastics produced, are not deposited in containers for subsequent removal to , centres, or.
In China, expanding cities are adding incinerators which are in turn adding to air pollution. Air pollution is caused by some sectors of the industry that are releasing due to their activity large amounts of chemical substances into the atmosphere every day, by the power plants and the engines that burn fossil fuels, by the stoves that are burning fossil fuels for heating during the winter , and by the daily human activities cooking, driving etc. The solid wastes usually find way to the landfills. This will hurt plants, along with animals and even humans who come into contact with the soil. A large numbers of industrial pollutants that come to human body through drinking water and contaminated food threaten the life and health.
