Honestly, the effects are endless. I'm currently working on this topic for my Master's (that what I should be doing right now) and when you really start to delve into the study of it, it's really quite disgusting because it affects everything we rely on to live.  But to sum it up, when the land is polluted, it really leads to pollution, destruction, and loss of everything else. The pollution makes it way into our water sources, kills plants, and  consequently, that is one cause that leads to the loss of animal species.  Polluted land is often treated with chemicals to "clean it up" that ends up in the soil and poisons our food sources.  The issue really is complex, but I encourage you to study it further.  You won't look at this world the same.

Arguably the principal source of air pollutants worldwide is motor vehicle emissions. While the U.S. has adopted stringent emissions controls, the EU has not been as assertive in this field; nevertheless, the U.S. is still the leading contributor to mobile source air emissions merely due to the very high number of vehicle miles travelled per capita. Underdeveloped countries lag severely in emission controls on motor vehicles, especially roadway vehicles, and on a per vehicle mile travelled basis produce many times the emissions of the U.S fleet.\n\nThe U.S., Russia, China and Japan lead the world in air pollution emissions; Canada is the number two country if measured in emissions per capita.\n\nPrincipal stationary pollution sources include chemical plants, coal-fired power plants, oil refineries, nuclear waste disposal activity, incinerators, large animal farms, PVC factories, metals production factories, plastics factories, and other heavy industry.\n\nSome of the more common soil contaminants are chlorinated hydrocarbons (CFH), heavy metals such as lead, which is found in lead paint and until recently in gasoline, MTBE, cadmium, which is found in rechargeable batteries, chromium, zinc, arsenic and benzene. Ordinary municipal landfills are the source of many chemical substances entering the soil environment (and often groundwater), emanating from the wide variety of refuse accepted, especially substances illegally discarded there, or from pre-1970 landfill that may have been subject to little control in the U.S. or EU.\n\nPollution can be the consequence of a natural disaster. For example hurricanes often involve water contamination from sewage, and petrochemical spills from ruptured boats or automobiles. Larger scale and environmental damage is not uncommon when coastal oil rigs or refineries are involved. Some sources of pollution, such as nuclear power plants or oil tankers, can produce widespread and potentially hazardous releases when accidents occur.\n\nIn the case of noise pollution the dominant source class is the motor vehicle, producing about ninety percent of all unwanted noise worldwide.

INTRODUCTION\nPollution, contamination of Earth’s environment with materials that interfere with human health, the quality of life, or the natural functioning of ecosystems (living organisms and their physical surroundings). Although some environmental pollution is a result of natural causes such as volcanic eruptions, most is caused by human activities.\n\nThere are two main categories of polluting materials, or pollutants. Biodegradable pollutants are materials, such as sewage, that rapidly decompose by natural processes. These pollutants become a problem when added to the environment faster than they can decompose (see Sewage Disposal). Nondegradable pollutants are materials that either do not decompose or decompose slowly in the natural environment. Once contamination occurs, it is difficult or impossible to remove these pollutants from the environment. \n\nNondegradable compounds such as dichlorodiphenyltrichloroethane (DDT), dioxins, polychlorinated biphenyls (PCBs), and radioactive materials can reach dangerous levels of accumulation as they are passed up the food chain into the bodies of progressively larger animals. For example, molecules of toxic compounds may collect on the surface of aquatic plants without doing much damage to the plants. A small fish that grazes on these plants accumulates a high concentration of the toxin. Larger fish or other carnivores that eat the small fish will accumulate even greater, and possibly life-threatening, concentrations of the compound. This process is known as bioaccumulation.\n\nTYPES OF POLLUTION\nPollution exists in many forms and affects many different aspects of Earth’s environment. Point-source pollution comes from specific, localized, and identifiable sources, such as sewage pipelines or industrial smokestacks. Nonpoint-source pollution comes from dispersed or uncontained sources, such as contaminated water runoff from urban areas or automobile emissions.\n\nThe effects of these pollutants may be immediate or delayed. Primary effects of pollution occur immediately after contamination occurs, such as the death of marine plants and wildlife after an oil spill at sea. Secondary effects may be delayed or may persist in the environment into the future, perhaps going unnoticed for many years. DDT, a nondegradable compound, seldom poisons birds immediately, but gradually accumulates in their bodies. Birds with high concentrations of this pesticide lay thin-shelled eggs that fail to hatch or produce deformed offspring. These secondary effects, publicized by Rachel Carson in her 1962 book, Silent Spring, threatened the survival of species such as the bald eagle and peregrine falcon, and aroused public concern over the hidden effects of nondegradable chemical compounds.\n\nA  Air Pollution \nHuman contamination of Earth’s atmosphere can take many forms and has existed since humans first began to use fire for agriculture, heating, and cooking. During the Industrial Revolution of the 18th and 19th centuries, however, air pollution became a major problem. As early as 1661 British author and founding member of the British Royal Society John Evelyn reported of London in his treatise Fumifugium, “… the weary Traveller, at many Miles distance, sooner smells, than sees the City to which he repairs. This is that pernicious Smoake which fullyes all her Glory, superinducing a sooty Crust or Furr upon all that it lights.…”\n\nUrban air pollution is commonly known as smog. The dark London smog that Evelyn wrote of is generally a smoky mixture of carbon monoxide and organic compounds from incomplete combustion (burning) of fossil fuels such as coal, and sulfur dioxide from impurities in the fuels. As the smog ages and reacts with oxygen, organic and sulfuric acids condense as droplets, increasing the haze. Smog developed into a major health hazard by the 20th century. In 1948, 19 people died and thousands were sickened by smog in the small U.S. steel-mill town of Donora, Pennsylvani

Oil refineries pollute the air by releasing or burning gaseous by-products of the refining process, such as naphtha, petroleum gas, sulfur, etc.  They also pollute the air by burning fuel to create heat and electricity which are used to refine oil.

Environment pollution is pollution of water, air, soil, noise, light , visual and radio active .\n\n Pollution is the release of chemical, physical, biological or radioactive contaminants to the environment. Principal forms of pollution include: air , water....\nAir pollution is a broad term applied to any chemical, physical (e.g. particulate matter), or biological agent that modifies the natural characteristics of the atmosphere. The atmosphere is a complex, dynamic natural 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.\n\nWorldwide air pollution is responsible for large numbers of deaths and cases of respiratory disease. Setting of air quality standards, such as the U.S. Clean Air Act, has begun to improve air quality for some pollutants. While major stationary sources are often identified with air pollution, the greatest source of emissions are actually mobile sources, principally the automobile. There are many available air pollution control technologies and urban planning strategies available to reduce air pollution; however, worldwide costs of addressing this issue are high. The most immediately available method of improving air quality is adoption of greater use of ethanol fuel (and other bio fuels) and increased reliance upon hybrid vehicle technology.\n\nYou can check out more your self.\nAir pollution :

lithosphere ,hydrosphere,atmosphere and biosphere are realms of earth.Deforestration should be stoped ,stop polluting ,there should not be extreme rise in population as more population more pollution and more deforestration.Deforestration and pollution are the main reasons that would be a danger to our echo system which will surely destroy echo system and our planet earth.

I guess you mean the gas ethylene ... this gas is released by ripening fruit and can cause unripe fruit to ripen. Insect damage is also known to stimulate ethylene release, but not necessarily damage by just any insect. Ethylene can affect plant growth negatively ...\n\n"The effects of ethylene on greenhouse-grown crops can range from none to severe. No other air pollutant causes a greater range of damage symptoms than ethylene gas (Rodgers, 1980). Symptoms include malformed leaves and flowers, thickened stems and leaves, lack of growth (stunting), abortion of flowers and leaves, bud and leaf abscission, epinasty (drooping and curling of leaves.)"

For benzene to undertake this addition reaction, it must be subject to heat (323K) and approx 400atm pressure.  In direct sunlight alone, there may be no reaction.  Addition of a catalyst drives electrophilic substitution towards C6H5CL + HCL

Well of course if you spill them, it's kind of nasty. Think of engine oil scattered in your garage. It doesn't smell good - can cause respiratory problems. It can contaminate your drinking water. It can kill fish and other marine organisms.\n\nIf you burn them, like you use them to generate electricity. They will produce carbon dioxide which can contribute to global warming. This carbon dioxide gas functions like a glass .. (Have you ever seen a greenhouse?) wherein heat is trapped and cannot get out. This is what we call " greenhouse effect". And since heat is trapped, earth becomes warmer. This could lead to melting of icebergs and polar caps and some islands to submerge.\n\nLooking for a tutor?

I am not exactly sure what answers you are looking for but here is what I can tell you.\n\nBenzene rings are very very stable because they are aromatic structures.  The Pi system of the benzene ring can however react with an electrophile.\n\nBenzene rings can also undergo substitution reactions with a number of constraints.  Because rings can not undergo SN1 and SN2 reactions like alkanes because their sructure does not allow for a backside attack with the nucleophile, nor do they have the ability to form a carbocation upon the dissociation of a leaving group.\n\nBenzene rings undergo two specific types of substitution.  \n1) Addition-Elimination\n-The nucleophile attacks the benzene ring at the carbon containing the leaving group.  A negative charge results.  The negative charge form resonance back in the ring by kicking out the leaving group.\n\n2) Elimination-Addition\n-A base grabs a proton in the ortho position to the leaving group and the electrons from the C-H bond are thrown into the ring forming a triple bond (benzyne).  A nucleophile attacks one carbon of the triple bond causing it to form a double bond and a negative charge in the ortho position to the nucleophile.  Upon acidic workup, the negative charge is protonated.\n\n---\nWith all of this said hopefully, you can deduce the correct answers to your question under the context of what you are currently doing in class.  Many different answers could fit the blanks.\n\nIf I were to answer your question as given, I would say: Benzene rings are very unreactive, but undergo substitution relatively high speed when an electron withdrawing group is present, on the carbon containing the best leaving group, but unlike alkanes do not participate in SN1 or SN2 reactions.\n\nI hope this helps!
