is the sum of the total of the elements, factors and conditions in the surroundings which may have an impact on the development, action or survival of an organism or group of organisms, such as, we human beings.
Humans and Environment Humans have had the ability to change their environment for thousands of years. Today this ability is greater than ever. This is because there are more people living now than ever before and human activity is concentrated in huge cities. Also, science and technology allow us to interfere with natural processes in more direct ways. Environmental pollution threatens human health.
Environmental Pollution Any undesirable change in physical , chemical or biological characteristics of air , land , water or soil, that is likely to have an adverse effect on the natural environment or life, is termed as environment pollution. The three major types of pollutions are: Air Pollution Water Pollution Land (soil) Pollution
Air PollutionAir pollution is actually harmful substances in theatmosphere, which damages the environment.With the development of industries, came alongthe increase in air pollution.
of Air Pollution onImpact h Human Health Polluted air contains one, or more, hazardous substance, pollutant, or contaminant that creates a hazard to general health. It is usually measured in terms of "particulate matter", or, the number of particles of these potentially hazardous substances as a percentage of air. Air pollution in cities causes a shorter lifespan for city dwellers.

Water Pollution Water pollution is the contaminationof water bodies(e.g. lakes, rivers, oceans, groundwater). Water pollution occurs when pollutants aredischarged directly or indirectly into waterbodies without adequate treatment toremove harmful compounds.
Impact of Water PollutionInfectious diseases such as typhoid and cholera can becontracted from drinking contaminated water. This is calledmicrobial water pollution. The human heart and kidney heart scan be adversely affected if polluted water is consumedregularly. Other health problems associated with pollutedwater are poor blood circulation, skin lesions, vomiting, anddamage to the nervous system. In fact, the effects of waterpollution are said to be the leading cause of death for humansacross the globe.

•Land Pollution is the degradation of Earths land surfaces often caused by human activities and their misuse of land resources. It occurs when waste is not disposed properly. Health hazard disposal of urban and industrial wastes,exploitation of minerals, and improper use of soil by inadequate agricultural practices are a few factors.
Impact of Land PollutionOver a long period of time, landfills start to emit landfill gases.Landfill gas is produced due to the anaerobic conditions that organicwastes decomposed in.Most waste buried in landfills give rise to hazardous and toxic liquidsknown as leachates. These leachates contaminate water sources,like the ground water below the landfills, leading to water pollution.Besides the points mentioned above, it is also important to note thatthese over-crowded dumps, contaminated sites and carelessdisposal of waste also contributes to air and water pollution, as wellas, acid rain.
The key Health Problems Caused by Land Pollution Since direct impacts of land pollution are air pollution and waterpollution, the key health problems caused by land pollution are sameas those of air pollution and water pollution and the additions areincreased human injuries, from syringes, broken glass and canswashing onto river banks and beaches.
Environmental Pollution a major concern Abating pollution is an exceptionally importantconcern because of pollutions’ harmful effects on theperson’s health, on climate and on the environment. Everybody is a stakeholder as we are all inhabitants of this one and only mother earth. Everyone should therefore be personally responsible for the upkeep of the environment through cooperation and active participation in making the atmosphere pollution free.
Students may also share the responsibility Lots of people are still unaware of the detrimental effects of pollution.Students can also help controllingpollution by informing and educatingpeople about pollution, in differentways. Some are like these:
