Litter corresponds to all the plant biomass that is delivered to the soil as dead organic matter. Its decomposition carries a big amount of CO2 production in the soil. (Wikipedia 2017). Litter decomposition is measured as the mass remaining of initial litter after a period of incubation. According to Lou and Zhou 2006, the decomposition is fast during some time from the beginning of the incubation, but after that, the remaining mass does not decrease so fast (figure 2.2.3). (Lou & Zhou 2006, 51). FIGURE 2.2.3. Theoretical litter decomposition. This behaviour is because decomposition can be organized in three phases: leaching, fragmentation and chemical alteration of dead matter. In leaching, rapidly growing bacteria can take really fast soluble materials as amino acids, organic acids and sugars for metabolic activities. During fragmentation, soil animals transform big pieces of litter in smaller ones. Chemical alteration consists in the degradation by bacteria and fungi of organic compounds to obtain energy, as some exoenzymes are released. These exoenzymes convert macromolecules in soluble products, that are processed by microbes and CO2 is released as a product. (Lou & Zhou 2006, 51) …show more content…
The exchange of litter mass can be described as: X=X_0 e^(-kt) Equation 2 Where X is the mass of litter, X0 is the initial mass and k is the specific decomposition rate (litter mass lost per unit of time and per unit of litter mass). (Lou & Zhou 2006, 54) Therefore, the equation shows the same as the graphics, that the mass remaining decreases exponentially with time. Oxidation of soil organic
In the Rio Grande Valley littering is a big issue when it comes to animals and their habitats. Many individuals tend to throw trash on the streets and oceans when they go to beaches, for example South Padre Island. When people go on vacations, they always leave their trash on the sandy beaches and do not pick it up. This kind of action result in a bird confusing the plastic garbage for food and consuming it. Garbage is very dangerous for animals it can injure them and damage their digestive system which can sometimes result in death.
The food that they throw away first goes to the dumpsters and then they end up in landfills. This is also where the dumpster divers, or “scavengers” as Eighner prefers to be called, begin their search for food (353). Where he mostly found a great deal of dumpsters was in the city. As he puts it, “the land is now covered with cities,” which means that there will be an abundance of trash that needs to be disposed of (361). This leads to more landfills needed to be made and that takes a toll on the earth. Dockterman has stated that “the buildup of decomposing organic material accounts for 16% of environmentally harmful methane emissions in the U.S.;” these emissions go into the atmosphere that we breath our oxygen from (Dockterman). Not only does this practice affect people survival-wise, but also the earth that billions of people live

Heather Roger's essay Gone Tomorrow: The Hidden Life of Garbage offers a compelling outlook on society’s excessive and uneconomical mass-production of goods (585). Rogers explains the process in which our garbage and waste are collected, processed, and discarded (Roger 585). From your kitchen, to the curb, then into collection trucks, to the processing unit, where they separate, recycle, burn, compact, and deposit your garbage in our Earth (Roger 585). Roger quotes “… Dumps are comprised of a series of earth covered cells” (Rogers 586). Landfills have used “Cells” to burry trash for decades and today’s cells are lined with a special material preventing the trash from leaking into the ground and rainwater (Roger 586). A cell can be up to 100 acres across and up to hundred feet deep (586). It takes years to fill a cell and after the cell is full it is “capped” and covered over with several feet of dirt (586-587).
Cai Gup-Qiang’s ‘Head on’ is overall an extremely large display. It consists of 99 wolf replicas and a glass wall. The wolves are running up then overhead then smash off a glass wall just to get up and start again. A single wolf by itself is a life size scale sculpture that is covered with fur; each one stands in a different pose some bearing their teeth others crashing into the glass wall. Many of the wolves are suspended on cables as to give the appearance of running. Then several are posed against the glass to give the look of crashing into it. The few wolves that are left look to be going back to the end of the line to begin again. There seems to be an inconsistency in the look of the wolves in the piece some look very ferocious and realistic, while
We always hear "do not litter!" or "throw your litter in the bins", maybe some of you bored to hear that yet we still do not throw it in the correct place. Litter is a serious habit problem to just throw away objects on the ground or leave them lying on the ground, instead of putting them in the garbage can. In Indonesia, the amount of litter is 175.000 ton/day and this is increasing every day. But we don't have to see that far, just look around us, our campus, Sanata Dharma University is still facing the littering problems. Each day, although there are various spots of bins and it is never full yet there are many litters lying in the floor, you can see the student hall as the evidence that even though it has 10 spots of bins, we still find people throwing their litter everywhere.
Almost two billion tonnes of food is waste around the world every year. Meanwhile, twenty million people suffer starvation in countries such as Yemen, South Sudan, Somalia, and Nigeria. Moreover, while farmers work hard to sustain the most essential element in civilization, almost one-third of the world’s population doesn’t even receive anything. Which is maddening that first world nations’ governments does not make actions on how to donate or maybe sell them for cheaper to countries that are in need instead of just dumping the food waste on landfills. Landfills have a huge impact on Earth for removing oxygen, which causes to break down aerobic process and as a result it releases methane. Furthermore, landfills will affect animals near it and

The passing of your beloved cat can be devastating. Your pet is a part of your family. When that time occurs, you will require closure the same as with other members of your family. Many people find that honoring them with a memorial service helps to commence their healing process.
Carbon-14 is unstable and its atoms decay into nitrogen atoms. (Biblical Chronologist). Willard Libby was the first person to measure the half life of radiocarbon, or carbon-14, recording it as 5730 years. When they are alive, plants absorb and digest carbon-14 from carbon dioxide.(Beta Analytic). They absorb their C-atoms via the foods that they consume. The absorption of the atoms stops when the organism dies. (Biblical Chronologist). Their carbon-14 content decreases gradually once they die. The rate at which the decrease occurs is determined by the law of radioactive decay. The amount of carbon-14 that is left in an organism after its death can be used to tell how old it is, its age. (Beta Analytic)
Composting is the process of biodegrading the waste material in which an enormous number of materials like hydrocarbons, nitrogenous compounds, acids, their derivatives and even other organic and inorganic substances can be remediated from the environment (Finstein et al., 1986). Compost pro...
Compost is an easy solution to eliminating the waste that our environment brings, while at the same time, providing many benefits to us, and the environment. By using compost, it improves our plant growth by enriching the soil that it drinks its nutrients from. It helps us avoid buying soil amendments such as peat, bark mulch and bagged manure. Compost also loosens the heavy clay that is in our soil, while improving the capacity to hold water and adding essential nutrients.
Humans and animals breathe out Carbon Dioxide, often referred to as the greenhouse gas, as a waste product. Plants take in this CO2 and use it to make food. This is called photosynthesis. During this process oxygen is released which is then breathed in by humans and animals. This procedure is repeated over and over and a natural balance is obtained. However this natural balance is disrupted by human activity. People of the world are putting more than 5.5 billion tons of CO2 into the atmosphere every year. 75% of this is caused from the burning of fossil fuels. These fuels are burnt all the time to run factories, power plants and vehicles. The main sources of CO2 emissions are electric utilities, residential buildings, industry and transportation. The other 25% is induced by the destruction of the world's forests. The reason for this is that there are less trees and plants to take in the CO2 but there is just as many, if not more, humans and animals to breathe it out.

...mproper way of disposing of waste and other materials. Littering not only impacts our environment but also many animals. Even though many people see littering being done they do not do anything to prevent this. One thing that may occur is that many of these wastes that are improperly disposed of finds its way to the ocean or other places. This is something that can be very dangerous for many aquatic creatures because they could think that it is food and this would cause them to choke on it and eventually die. A lot of people litter because they really have no idea of the damage that they are causing our environment. Another reason why people do this is because they are too lazy to dispose the materials into a proper trash can. Most of the litter that is being thrown on the ground eventually goes and finds its way into the sewers and goes into the oceans and lakes.
