HOPE YOU ALL HAVE AN ENVIRONMENT FRIENDLY YEAR AHEAD!!!!!!!!!!

    From this point of view the primary purpose of knowledge environments is to host and support activities of knowledge building, the means including cognitive ergonomics, social software, immediate information access exploiting means of multimedia and hypertext, content contribution functionalities and structured ontologies.
From another perspective, the purpose of a knowledge environment can be defined as to facilitate consistent knowledge outcomes. Knowledge outcomes reveal themselves as learning, communication, goals, decisions, etc. Consistent knowledge outcomes imply predictable learning results or replicable communication results and predictable quality of decisions. The design of knowledge environments is both commonplace activity and specialised expert work. At a simplistic level every teacher, every author, every librarian and every database manager is a creator of a knowledge environment. At a specialised level knowledge environments need sophisticated architecture and modeling capabilities. This is necessary when the creator of the knowledge environment wants to deliver replicaple results in hundreds of specific instances of the same knowledge environment. On the other hand, the strengthening trend of public authorship leads to open-ended ontologies by means of, say. tagging or folksonomies. In a significant sense, knowledge environments are in such cases created not only by their authors or owners but also by the contributors of their ontologies.

POLLUTION

                                                             POLLUTIONPollution is the introduction of contaminants into the natural environment that cause adverse change.Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Pollution is often classed as point source or nonpoint source pollution.There are four types of pollution.They 
are :
1]AIR POLLUTION 
2]WATER  POLLUTION
3]SOIL POLLUTION
4]NOISE POLLUTION

                            AIR POLLUTION

Air pollution is the introduction into the atmosphere of chemicals, particulates, or biological materials that cause discomfort, disease, or death to humans, damage other living organisms such as food crops, or damage the natural environment or built environment.

The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth's ecosystems.

                                                 WATER POLLUTION

Water pollution is the contamination of water bodies (e.g. lakes, rivers,oceans, aquifers and groundwater). Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds.

Water pollution affects plants and organisms living in these bodies of water. In almost all cases the effect is damaging not only to individual species and populations, but also to the natural biological communities.

                                                        SOIL POLLUTION

Soil contamination or soil pollution is caused by the presence of xenobiotic(human-made) chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals, or improper disposal of waste. The most common chemicals involved are petroleum hydrocarbons, polynuclear aromatic hydrocarbons (such as naphthalene and benzo(a)pyrene),solvents, pesticides, lead, and other heavy metals. Contamination is correlated with the degree of industrialization and intensity of chemical usage.

The concern over soil contamination stems primarily from health risks, from direct contact with the contaminated soil, vapours from the contaminants, and from secondary contamination of water supplies within and underlying the soil.Mapping of contaminated soil sites and the resulting cleanup are time consuming and expensive tasks, requiring extensive amounts of geology, hydrology,chemistry, computer modeling skills, and GIS in Environmental Contamination, as well as an appreciation of the history of industrial chemistry.

NOISE POLLUTION

Noise pollution is excessive, displeasing human, animal, or machine-created environmental noise that disrupts the activity or balance of human or animal life. The word noise may be from the Latin word nauseas, which means disgust or discomfort. The source of most outdoor noise worldwide is mainly construction and transportation systems, including motor vehicle noise, aircraft noise, and rail noise. Poor urban planning may give rise to noise pollution, since side-by-side industrial and residential buildings can result in noise pollution in the residential areas.

High noise levels can contribute to cardiovascular effects in humans, a rise in blood pressure, and an increase in stress and vasoconstriction, and an increased incidence of coronary artery disease. In animals, noise can increase the risk of death by altering predator or prey detection and avoidance, interfere with reproduction and navigation, and contribute to permanent hearing loss.

SMOKING KILLS

                 PLEASE STOP SMOKING

SMOKING POLLUTES THE EARTH 

                                        *]  (NEW YEAR CELEBRATION IN AUSTRALIA)

Deforestation, clearance or clearing is the removal of a forest or stand of trees where the land is thereafter converted to a non-forest use.^] Examples of deforestation include conversion of forestland to farms, ranches, or urban use.

About half of the world's original forests had been destroyed by 2011, the majority during the previous 50 years.^] Since 1990 half of the world's rain forests have been destroyed. More than half of the animal and plant species in the world live in tropical forests.

The term deforestation is often misused to describe any activity where all trees in an area are removed. However in temperate climates, the removal of all trees in an area—in conformance with sustainable forestry practices—is correctly described as regeneration harvest. In temperate mesic climates, natural regeneration of forest stands often will not occur in the absence of disturbance, whether natural or anthropogenic, biodiversity after regeneration harvest often mimics that found after natural disturbance, including biodiversity loss after naturally occurring rainforest destruction.

Deforestation occurs for many reasons: trees are cut down to be used or sold as fuel (sometimes in the form of charcoal) or timber, while cleared land is used as pasture for livestock, plantations of commodities and settlements. The removal of trees without sufficient reforestation has resulted in damage to habitat, biodiversity loss and aridity. It has adverse impacts on biosequestration of atmospheric carbon dioxide. Deforestation has also been used in war to deprive an enemy of cover for its forces and also vital resources. A modern example of this was the use of Agent Orange by the United States military in Vietnam during the Vietnam War. Deforested regions typically incur significant adverse soil erosion and frequently degrade into wasteland.

Disregard or ignorance of intrinsic value, lack of ascribed value, lax forest management and deficient environmental laws are some of the factors that allow deforestation to occur on a large scale. In many countries, deforestation, both naturally occurring and human induced, is an ongoing issue. Deforestation causes extinction, changes to climatic conditions.

CLEANLINESS IS IMPORTANT

1) THE CLEANEST COUNTRY IN THE      WORLD (CANADA)

2) ONE OF THE DIRTIEST COUNTRY IN 
THE WORLD (GHANA)


BUT IF WE TRY WE CAN BRING THE CHANGE .............
