REDUCED VISIBILITY/CLARITY OF AIR

A combination of the following happenings:
Debris and particulate release due to rapid economical activities in mining and timber
Occurrence of natural disasters due to volcanic eruptions
Mass utilization of transportation of diesel-petrol fuel based
Uncontrollable emission of volatile chemicals as byproduct from machineries in industrial plants
Indiscriminate open burning at large scale on land

will result in
Haze and Smog

LIFESTYLE

Combined extent impacts of air, water, and land pollution will cause irreversible environmental damage which is permanent, and will lead to toxic environment similar to Mars and Jupiter. As a result, the earth will be uninhabitable environment for every living organisms. This will lead to:
  • high rates of extinction of biodiversity and high rates of death rates of human
  • the rapid undergoing of adaptable species to mutate to better evolve in the sudden change in environment.
Therefore in search of survival on Earth for humans:
  • a city is covered up with shield where communities activities are one freely together and protected from the harsh environment outside.
  • water resources becomes scarce, leading to rationing and search for alternatives, development of synthetic liquid similar to water.
  • unusable land due to toxic soil will change agricultural practice; poisonous foundation for humans to stay on in effect human habitat will be shifted underground to support large population.
  • artificial synthetic air/recycled air/purified air used as a result of poisonous atmosphere.
  • a protective suit with astronomical-like features are used in rendezvous outside shielded city into the polluted environment.
  • alternative food supplies consumed as wide spread species extinction and mutation which are toxic and poisonous.
  • emergence of evolved species due to mutation which are predatory and dangerous to human populations.
  • economies change due to changing human activities in order to adapt to the new living environment.

OZONE DEPLETION AND ACID RAIN

Ozone depletion
Ozone layer is a protective layer in our atmosphere (O3, three oxygen atoms). It's about 19 to 30 km in distance from the Earth surface. It plays an important role of blocking ultraviolet (UV) rays that come from the sun, which, if there was no ozone layer ever, cancer would dominate and even no life would be in this world! The concentration of the layer is usually under 10 parts ozone per million. The ozone layer is made up by the action of sunlight to oxygen, and the amount is stabled by the existence of nitrogen. 
In today's trends there is a noticeable depletion of the ozone layer. It's popularly known since 1970 that a substance called CFC (chlorofluorocarbon) is threatening the layer


Acid rain
Acid rain is the kind of precipitation that contains larger amounts of acid than normal. Rainwater is usually slightly acidic, with pH level between 5 and 6. Water that evaporates from earth is neutral (pH 7) and it becomes weak acid when mixed with carbon dioxide in the atmosphere. Acid rain contains more pH than ordinary. This is caused by the presence of air pollutants, like sulfur dioxide and nitrogen oxides. They produce acids if combined with water. Acid rain is considered as the wet deposits of air pollutants, where it's combined with moisture before falling into the ground. While air pollutants that fall without combining with moisture is called dry deposits.
Acid rain can occur naturally, from the volcanic eruptions. However we are also causing this, from the emission of vehicles and of industrial plants that include the burning of fossil fuels. If we continue to increase rate of air pollution, we are increasing the risk of acid rain to happen.
What's the impact of acid rain?
  • Deteriorates building that is made of rock
  • Acidification of soil and lakes
  • Separation of poisonous minerals such as aluminum and mercury from the surrounding ground, increasing the risk of contamination to lakes/water sources
  • Deteriorates trees and forests

CLIMATIC PATTERN CHANGE

A combination of the following happenings:
  • Rapid emission of greenhouse gases from mass utilization of transportation & heavy industrial economic activities
  • Clearing of land leaving an exposed idle barren land
  • Chemical composition of atmosphere altered
  • Natural disasters of frequent volcanic eruptions
finally cause

ALTERATION TO GEOGRAPHICAL LANDSCAPES

A combination of the following happenings:
  • Constructions of housing and industries for development
  • Economical activities of mining, timber and agriculture
  • Clearing of rainforest and hillside, with natural disasters like earthquake which involves the shifting of earth surface 
finally cause

ECONOMICAL EFFECTS

In the course of development, many basis for sustainable development is often ignored. In the aim for environmental management, private investors often opting for lowest risk with highest profit takings in its ventures are ignorance to thorough plans, analysis and assessments on environmental impacts done.
Even if such assessments are taken into account and cautious measures implemented, pollutions are still happening rapidly as each nations would not want to be left out in the race for globalization, and also inevitable as pollution has been happening for a long time.
Continuous development for globalization due to increasing activity of agriculture, industrialization, fisheries, timber and mining will lead to:
  • rapid and excessive constructions of factories and building
  • increase in emissions of toxic and poisonous gases
  • destruction of ecosystems
And finally they will lead to permanent and irreversible damage to the environment. 
In the events of pollution occurs which are reversible, greater finance and grants are needed for the following purposes:
  • conservation of remaining ecosystem
  • rehabilitation contaminated ecosystems
  • clean up of toxic waste
  • restoration of historical landscapes
  • revival of biodiversity to a new ecosystem
  • preservation of endangered species

FOOD CONTAMINATION AND FOOD WEB DISTORTION

Food contamination leading to food shortage
A combined event of (a) free flow and emission of non biodegradable industrial discharge and noise disturbances due to usage of heavy machineries; (b) illegal dumping and spraying of toxic and hazardous chemicals on land and water; and (c) mismanagement in regulation of treatment and control of heat and radioactive substances; will lead to high density toxicity concentration on soil, water and air. The impacts of this are:
  1. Fertile land becoming poisonous for living organisms underground and agriculture practice, nutrients lost, locked up or becomes toxic
  2. Aquatic ecosystem depletes further and non-consumable water supplies noxious fumes and gas permeates, blanketing atmosphere
  3. Detrimental health to psychological and physiological being of organisms in ecosystems

Food web distortion
A combination of (a) mass viral infections and attacks on certain organisms; (b) contamination and pollution of food supplies which is inedible; and (c) uncontrollable hunting of exotic/rare/endangered species will lead to the disequilibria of species population. The next impact will be the imbalance in the ration of producers, consumers and decomposers in the ecology system, which consequently distorts the pattern of energy flow through the chain/web. This will bring to disruption of ecological food pyramid.
When ecological food pyramid is disrupted, insufficient consumption of food cause organisms deprived of energy, thus affecting the organism's metabolism of its biochemical activities. Then, growth and development of organisms will be affected, and leads to mass starvation and mortality in world population. On the other hand, particular species extinction occurred while its predators dominates, thus ecological niche in ecosystems change.
