Some of the ideas presented by the meeting of Lies ing ideas. Presented by Laclau Mr. Larguizabal in working joran of 12/18/2009 city council.
The reasons for promoting and maintaining the trees ornamental obey human, spiritual, and ecological health. Local governments spend large sums to produce (or acquire) trees, planted and maintained in good condition and in accordance with the limitations of space in which they develop
- In these terms the company has the benefits of an urban landscape embellished and healthy and although these services are enjoyed by the society in general, are close neighbors or those who routinely frequented a particular neighborhood who benefit most.
- You do not have the same appreciation of value (monetary or non- monetary) that a treeless street trees. Nowhere in the world. Or between one with small trees or other plants years, often related their own growth with the personal history of many neighbors. Society and governments know that there are ordinances and defending the biological heritage of vandalism or replacement arbitrary management of prunings even when performed by unauthorized personnel.
- Being a property has value and this value is not only subjective. Monetarily, the sum of all the investment and expenditure for maintaining street trees, which is paid by taxpayers, is at least the capital value of these assets alive. However, payments are not only for its perceived benefits (as a tree grows or purchase initially sustained for many years), but also for the present and future.
- In this sense, the trees on city streets meet ecological and social functions that provide services such as: (1) improvement of the urban landscape through the many attributes of form, color, occupation of space, angles vision, etc., which follow similar rules of artistic expression and disciplines dealing with landscape assessment, (2) green lung function, attenuating towards dissipation housing carburizing gas motor, retaining soot and solid contaminants and oxygenate the air through biological processes, (3) recreation and spiritual solace for the vast majority of people, one of the few urban elements that link the man with the environment, (4) refuge from urban macro and micro, including birds that are appreciated by the people, with its consequent negative impact morigeración (eg litter, etc.) on buildings and other public or private works, (5 ) cases, temporary shelter for migratory birds coming from long distances and require strategic OWL to support their routes, (6) mitigation urban microclimate, particularly (i) the heat from direct sunlight in summer, combined with (ii) as a light filter that attenuates or reflects radiation that are harmful to human health, (iii) mitigation of impacts of heavy rain, wind or hail, direct interception and runoff from the trunks, or by diverting and weakening wind fillets, (7) together with the adjacent quarry, are the only reservoirs of pet droppings before absolute lack of control that exists in the city about responsible pet ownership, (8) substantial element of climate change mitigation, the remove atmospheric carbon dioxide (and retain soot and other solid pollutants that cause the greenhouse effect) that transforms wood and keeps it stored for long periods of time, sustaining this process continuously throughout their lives.
- The above services will meet and grow with ancient trees, which to keep these functions must be preserved and maintained so as to minimize risks to people from falling ill or thick branches, or even senescent trees and other obstacles. In Mar del Plata, in general the management of pruning is appropriate to meet these conditions and maintain trees for many years in good condition.
- Services Comments adaptation (2, 5, 6) and mitigation (8) are climate change, along with aesthetic and spiritual values \u200b\u200bthat result from the existence of urban trees, which are fundamental for local development and contribution to ecological processes with global implications .
- In that sense, it is highly disturbing that mature trees are removed to widen streets in a city that has few green spaces in terms of size and No of inhabitants. Since February ultimo, more than 1000 cities around the world have pledged to work to reduce or offset emissions of greenhouse gases in an agreement of mayors promoted under the current Climate Change Summit in Copenhagen.
- For Liberty Street, where there are a variety of tree species (white acacia, ailanthus, banana, etc) of good development and size, one can assume that, considering stem, branches and roots permanent (and foliage , rootlets and twigs in constant regeneration) each tree, on average (based on diameter, height and wood density) remains sequestered from 100 to 200 kg of carbon (C), equivalent to 367-784 kg of carbon dioxide equivalent (CO2 equivalent, a unit of measure or capture emissions of greenhouse gases in the atmosphere). Multiplying this amount by the number of trees to remove (Almost all found in single file, and at least half of those planted with double row) would have the amount of total emissions from deforestation could contribute to climate change by the City. In addition to this contribution, add cement consumption (whose industry is important causal greenhouse nationally and globally) and the fossil fuel use in asphalt and machinery for the proposed expansion. In addition to the emissions caused by tree removal would eliminate the annual capture function, while new plants (if installed again) take many years to reach the levels of plant uptake current.
- also on an estimated basis, one might assume that (assuming that the current carbon storage has been acquired in 40 years), each adult tree of Liberty Street to absorb an average of 9-18 kg of CO2 equivalent. These estimates should be refined but show an idea of \u200b\u200bthe magnitude of carbon sequestered or kidnapping are not considering the proposed work.
- On the other hand, in times of pruning this year and even in inner-city disadvantaged people can be seen gathering pruning branches. This service also unthinkable to poverty would be lost with the loss of trees.
- Today, is moving a central terminal, to take it to another central location, with casts doubts the usefulness of a medium-term measure that does not seem to solve the current problems of movement of buses. Currently, however, buses run by large sections of town (Av. Champagnat, Juan B. Justo, Luro and Columbus, and streets around the terminal Sarmiento). With the new terminal, the input or output using a much smaller segment of Av Champagnat (considering that most of the minibus runs to and from Buenos Aires) and Liberty Avenue in the state that is, changes positive transit should be apparent, no need to proceed with any expansion that affects other social services, such as those discussed above.
- In any case, an expansion would be a logical consequence of a formal impact study on the implications of traffic shifted from the old to the new Terminal. And there should be a work attempt "in case" or "to improve", offsetting the benefits already mentioned.
- Finally, many elements of society would have to ask the current leaders accountable on investment and effort applied by his predecessors in the generation and biological heritage of the city as capitalizing on the values \u200b\u200bapplied in urban forestry payable by taxpayers would have to be an important asset not only social, but real monetary assets (although the national or municipal accounts not counted), which continues with its life, and you can not terminate an interest but higher consensus and in consultation with affected parties, particularly the residents of that street. Again, if realized, Mar del Plata would be a wrong way to your destination city clean. In light of sanitation activities (eg the landfill), which is facing the Municipality with support from the national government, a negative attitude in this case it would be surprising and inappropriate.
n therefore is where marplatenses said he wanted to be. 
. 
In fact, Liberty is an artery-widening subject to the advice of the Zoning Code, but much of its consolidated afforestation drive a landscape that many of the neighbors want to preserve, as well as the extension of sidewalks . 
too many lies for so brief an article that we reproduce 
In that regard, he recalled that "since he started this several years ago, I was opposed to the place because I felt it was inappropriate" and argued: "I always thought the place was the loading station of Avenida Juan B. Justus is a conceptual error put two terminals in a place that is traditional in Mar del Plata, as is the neighborhood of the station. " 
They add that "there are other reasons we have considered: The floors throughout this area are defeated in life (to be built over 50 years), are broken, maintenance and breach slopes drains, so the water remains stagnant with each rainfall, however small it may be. The constant heavy traffic will affect the vast majority of the buildings in this neighborhood are old and cause cracks, leaks, burst pipes, as well as public facilities infrastructure. The announced route will produce profound changes in this neighborhood, it will cause air pollution, vibration and noise, all harmful to health, "he enumerated.
