how do the landfills affect the earth?

Landfills require a LOT of space. Only certain areas can become landfills. There is also the smell and the cost. Some older landfills have no lining at the bottom so sometimes liquids in the landfill can seep deep into the ground and destroy the fertility of the soil and possibly contaminate the water supply.

They don't care about what happens to the Earth,but\nIF everyone littered,then the world would be a big garbage\ncan,and it will get hot,and the sun would make the Earth\nsmell just like Garbage Dump!\n\nGross! KEEP THE WORLD CLEAN EVERYONE! PLEASE!

Forest cover tends to create areas of groundwater recharge and generally slows runoff. Trees tend to buffer the speed which rainfall hits the ground and because they often create areas covered with organic material like leaf litter, the ground has more time to absorb rainfall before it runs off. Bare ground will be subject to erosion as well as higher rates of runoff. \n\nThe burning of trees may contribute to CO2, but is probably insignificant because it is a one time event. The removal of the trees is likely to be accompanied by a long term loss of soil organics, which will also contribute CO2 over time. The real change may be through albedo effects and changes in rainfall related to loss of trees may be an even bigger factor. In Brazil,when trees were removed to be replaced with even darker colored soil, the average temperature of the area increased by about 3 degrees C. Most cities have a heat island around them, often 10% warmer, due to changes in albedo. The lack of trees may change the rainfall patterns, and some hypotheses actually predict that even rain drop size may change. A study in Amazonia known as the Large Scale Biosphere-Atmosphere Experiment is investigating these ideas.

It is true.  I don't know that they can be recycled, and they don't break down.  That is a problem.  This stuff will fill landfills soon.

Disposal methods also vary widely. In Australia, the most common method of disposal of solid waste is to landfills, because it is a large country with a low-density population. By contrast, in Japan it is more common for waste to be incinerated, because the country is smaller and land is scarce.\n\nMany local authorities (especially in urban areas) have found it difficult to establish new landfills, due to opposition from adjacent landowners. Few people want a landfill in their local neighbourhood. As a result, solid waste disposal in these areas has become more expensive as material must be transported further away for disposal.

The worst thing that'll hurt the Earth is getting melted by the Sun when it grows from a small yellow star into a red giant star in about seven billion years, as estimated by astrophysical calculations.\n\nThe Sun will  transform all the hydrogen it has into helium by fusion of hydrogen nuclei into helium nuclei. The helium will accumulate in the Sun's nucleus, and the Sun's volume will increase. Its temperature will also increase. As a consequence, In about three billion years, water in the Earth's oceans will evaporate. In about seven billion years, the Sun will ultimately swallow Mercury, and its temperature will be so high that the Earth's rocks will melt.\n\nAfter that, the Sun will have burned all the helium in it and shrink into a white dwarf star, so the Solar System, including the Earth, will freeze.\n\nThat will mark the end of the Earth, and so it will be the thing that will hurt it most.

It kills the microorganisms.  It also tends to remove air from the soil making it harder for larger organism (like insect grubs and earthworms) to breathe.\nIn addition it upsets the natural chemistry or the soil.

Greenhouse effects increases the temperature of earth and it will make the poles melt. This would result in cold water entering the oceans and everything will eventually freeze. And then the production of Greenhouse gases will stop so greenhouse effect will exist no longer leaving an Ice Age. But if it continues then finally one day (after 1000 years or more...) earth will become a barren rock.

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.

We were given the work of caretaker of the earth.\nThe Earth Will Be Saved. In spite of the environmental gloom hanging over the earth, we would like to think that it will survive. After all, it is our home—and hopefully the home of our children and their children.  The truth is that while most people are concerned about the environment, many think nothing of throwing trash on the ground, dumping garbage in a river, or leaving lights turned on when they are not being used.  Such acts may seem like small things, but if each of the billions of individuals on earth were careful about how he treated the earth, it could make a difference.  Such things as being conservative in the use of energy, cooperating with recycling programs, and disposing of trash properly make a contribution toward preserving the environment.  By our habits we can demonstrate our care for the earth now.\n\nA comment by Thilo Bode of the Greenpeace organization, as quoted in Time magazine, touches on the core of the environmental problem:  “Our principal aim has been that corporations should consider how their products are disposed of.  They must think in terms of a trilogy: production, use and disposal.”  Sadly, we are able to make goods, we know how to use them, but we do not dispose of them properly. In some cases humans simply do not know how to do so safely.\n\nHowever, there is a greater solution.  Humans are limited, but earth’s Creator is not. He has already demonstrated his excelling wisdom in the creations we see on the earth. He knows how to make, to use, and to dispose of things properly.  Many of the systems he has made are automatic.  A seed germinates, and a plant grows and produces fruit.  It then dies—with all of its elements breaking down in nonpolluting fashion, ready to be reused.  This is recycling at its best!  There is no toxic pollution!\n\nThe Creator does not intend to let the earth deteriorate into an uninhabitable trash dump. In the Bible, at Isaiah 45:18, we read:  “This is what Jehovah has said, . . . He the true God, the Former of the earth and the Maker of it, He the One who firmly established it, who did not create it simply for nothing, who formed it even to be inhabited.”  The Bible explains that man was originally put in a paradise. In fact, God purposed that this Paradise reach the ends of the earth and be filled with people. (Genesis 1:28.)  However, rebellion broke out.  The first man and woman did not want to continue subject to God’s rule.  \n\nNevertheless, God has not turned a blind eye to earth’s ruination. He will act before it is too late, before the earth becomes an uninhabitable wasteland. How do we know that?  Revelation 11:18 explains: “The nations became wrathful, and your own wrath came, and the appointed time . . . to bring to ruin those ruining the earth.”  \n\nGod’s original purpose for the earth, that it be a paradise, will still be fulfilled.  God issued statements showing this.  For example, he said:  “My word that goes forth from my mouth . . . will not return to me without results, but it will certainly do that in which I have delighted.”  (Isaiah 55:11)  You may enjoy reading Isaiah chapter 35, where God describes the transformation of ruined lands into gardenlike parks and fruitful fields.\n\nEven now, when pollution is stopped, the earth has shown a remarkable capacity to renew itself.  God created it to do so. If the overloading of the earth with pollutants is discontinued, a wide variety of microorganisms in water and soil can heal much of the damage.  Additionally, there is reason to believe that when God steps in and directs things, this rejuvenation process will be even more effective. He can provide the training and perfect direction that humans now lack.\n\nHence, the earth’s future is not hopeless.  Plants and animals will be saved.  Endangered species lists will be gone.  Our air and water will be fresh again.  Obedient humans will be there to enjoy it

If is landfill u mean hear is this:\nLandfill is a waste disposal site for the deposit of the waste onto or into land (i.e., underground), including: internal waste disposal sites (i.e., landfill where a producer of waste is carrying out its own waste disposal at the place of production), and a permanent site (i.e., more than one year), which is used for temporary storage of waste, but excluding: transfer facilities where waste is unloaded in order to permit its preparation for further transport for recovery, treatment or disposal elsewhere, and storage of waste prior to recovery or treatment for a period less than three years as a general rule or storage of waste prior to disposal for period less than one year. [1]\n\nIn the U.S., landfills are regulated by the state's environmental agency that establishes minimum guidelines; though no guideline may fall below that of the U.S. EPA. Most modern landfills require a minimum of one containment liner, consisting of a compacted clay with a minimum thickness and maximum hydraulic conductivity; compacted to 95% of maximum compaction. Others also require the addition of a layer of high density polyethelene (HDPE), as an impermeable membrane. Various final cover (capping) systems are used, depending on the type of wastes present within the landfill.\n\nIn eras before the mid-20th century, landfills were the main method of waste management. In the late-20th century, alternative methods to waste disposal have been suggested, including recycling, converting to biodegradable products, incineration and cogeneration facilities, all of which assist in reducing the total amount of wastes disposed in to landfills. Some countries, such as Germany, have entirely banned the disposal of untreated waste in landfills in the early 2000's; there, only the ashes from incineration or the educt of mechanical biological threadment plans are still deposited.\n\nA landfill also may refer to low-lying ground that has been filled in so that it can be used for a specific purpose, such as building houses. Soil and rocks are use to fill in the space instead of waste materials. Unless they are stabilized, these areas may experience severe shaking or liquefaction of the ground in a large earthquake.\n\nFor More:http://en.wikipedia.org/wiki/Landfill

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

Both are present in small amounts in soils and rocks.  Spillage from waste dumps can be a source also.

I would guess it would include old solar panels and various pipes, etc. that no longer function.  There would also be industrial waste from the manufacturing of this material (air pollution, water pollution, etc.)
