" L ' ecology is the science that studies the relationship between the living and the environment. The ecology asks how to make living things suit the environment in which they live. The geography of giving helps the ecology of the contributions. The main one is the relationship between the environment and man . It 'very important because you can understand how people can live in a particular place, making enough natural resources of an environment. Ecology sa identify positive or negative consequences of human actions on the environment..

" E psychology helps us to know and environments population.
Ecology seeks to understand how a living being can live in a certain environment.
contributions that ecology can provide geographical survey are very numerous: the ecology are necessary to determine how many people can live in a certain environment, having a lot of resources.
Then there is the observation of positive or negative consequences of human intervention on a variety of environments, to discover states of degradation and make proposals for environmental remediation ..

"Ecology is the science that studies the relationship between living organisms and the environment.
It can not be separated from man and the man who created the ecological problem.
Primitive man looked after the environment, but after the invention of tools, fire and after the industrial revolution began to neglecting the environment and change it..

" E ffetto greenhouse generated by humans occurs over millions of years. The population has surpassed the 2 billion 80 years ago. The processes of production, in the twentieth century, made it unthinkable a result of human activities on climate. Since the advent of 'industrialization there was a growing population. Since then, the fuel consumption are becoming more usual in everyday life. This has led to increased pollution by man 's through carbon dioxide, but also because of methane generated by the steps of digestion-rot. It seems that, according to some Russian scientists also
the melting of ice at the North Pole will result in the release of a large amount of methane, which will further enhance the greenhouse effect. ". Digimon King and Cia 778, 1G
I CLIMATE CHANGE IS A GLOBAL ISSUE
Over the past 100 years, the climate has changed very quickly. According to European scientists temperatures will rise by 6 ° C and this rapid increase in temperature could cause melting ice caps . Climate change is detected for example by increased precipitation, which may cause disastrous floods. According to many scientists to global warming due to pollution and the greenhouse effect. The greenhouse gas are produced by industries and the heating of homes and offices. These are the greenhouse gases in the atmosphere blocking sunlight to dissipate heat into space. Some countries have signed international conferences and protocols, with which it was decided to undertake a struggle to emissions but the 'America and Australia have not signed the Kyoto Protocol, which is a maximum limit of emissions for each country.. "and I know , 1G
THE PENTAGON AND CLIMATE CHANGE "The Pentagon (U.S. military organ), studying the environmental effects of climate change, concluded that these could cause wars. The rising sea levels and high temperatures will cause problems on America and other continents. Scientific research has created imaginative scenarios in the filmography as well as Hollywood has produced several films catastrophic, including "The Day After Tomorrow." The average temperature in recent decades has risen by 1 ° and is thought to have already implemented a reduction in the intensity of ocean currents like the Gulf Stream, to the point that some scholars believe to rapid intensification and frequency of traffic extreme weather around the planet. Governments should therefore take quick resolutions with respect to the environmental problem, since even the available resources we looted, have already reached the limit: the planet Earth, in short, is already in the reserve last year. Hall and Christ, 2G.
"There are troubling news on the future of our planet : the process of global warming, which is spoken by many years, it is always faster and less controllable. Global warming is the phenomenon whereby the earth's temperature increases. The speed with which our planet is warming is greater than what was expected . In 2001 it was calculated a global warming of about half a degree higher than the average temperature of the planet as normal. But then with the new tools it is seen that between 2001 and 2006 the temperature has risen by 0.50 ° to 0.71 °.
What could happen in Italy?
seeing an increase in so-called extreme weather events, with the emphasis on the problem of drought. The climate conference in Paris has clarified the responsibility of the acceleration of global warming. Unfortunately, it is virtually guilt man. But now the word has to go to scientists and politicians ... it is their responsibility to save the world before us.

" forms of energy
In the world there is the energy of the sun, wind, water, fire, volcanoes and water. In the world of solar power plant with carbon dioxide and water means that plants can feed themselves through photosynthesis. Energy can take many forms: chemical, mechanical , heat, light , electricity, nuclear .
The energy sources can be: renewable and nonrenewable . Renewable energy sources are natural, inexhaustible, which are continually being renewed: solar energy , wind, biomass , geothermal, hydroelectric , Maritime . Are all the other non-renewable forms of energy that can not be renewed as: gas, coal , oil.
Solar panels are a kind of radiators blacks containing a fluid (air or water), exposed to solar radiation, generate hot water for sanitation purposes, and we warm up the rooms
Solar energy: the sun causes reactions of nuclear fusion and transform hydrogen into helium, releasing enormous amounts of energy.
Energy from biomass : plants, through photosynthesis, converting solar energy accumulated carbon dioxide into organic matter (biomass). The forest is a huge plant biomass (wood). The wood can then be cultivated as any other plants. Although the residues of agricultural crops are used to produce biomass energy.
Hydropower is produced by the rainwater that can be collected in large artificial vessels: the dighe.L 'water contained in these basins, is dropped into a penstock, which leads the hydroelectric real own, which turns a turbine. The turbine is coupled to an alternator that rotates to produce electricity. Since the fall of water are obtained great powers. This energy is the most used and least expensive.
energy from waste?: each citizen produces about 500kg of waste annually. The most recent legislation imposes an obligation to reduce waste at source and recycle the collected fractions separately. The incinerators should use part of the waste that can not be recovered or recycled to produce electricity or heat. They are also called cogeneration from waste. - Ed : Recent news of the news disseminated by the media concerning the incinerator Colleferro (Roma), there are encouraging virtuous use of these facilities, which too often end up toxic waste illegally disposed dall'ecomafia. Unavoidable then the issue of dioxin that has a high public health impact .-.
Nuclear power: whenever the nuclei undergo a transformation is a liberation of energy. Energy is generated by fusion reactions and nuclear fission.
In other words, the matter turns into energy. In nuclear fusion, hydrogen atoms fuse into helium atoms and in nuclear fission exploits the properties of some elements, to break down into lighter elements, releasing energy.. BUGGIANO 3, 1G
" The energy savings can be achieved by increasing the ' energy efficiency in homes. What to do? For example, follow these simple rules :
1) Lighting: Use energy-saving lamps
2) Household: Use full load washing machine and dishwasher choosing programs at low temperatures.
3) Do not keep the doors open the refrigerator and check the seals every day.
4) Heating: Keep the daytime temperature of 19-20 degrees and 10 degrees at night 5) C ondition : clean the filter often conditioner 6) Do not leave TVs on standby, radio, telephones. V al. Sam., Fed, 1G
Ang. and Lor., 1G on savings enegetico: "To save energy, we must reduce daily consumption. To do this we must buy energy-saving bulbs that last longer and consume less. Even if you have these bulbs in the house should not be left on continuously, especially during the day. In Italy you should put more solar panels on the roofs of houses, because they exploit the 'power of the sun, transforming it into electricity. Another source of renewable energy is that of wind turbines, which use wind to turn it into energy. There are many other ways to produce and save energy, but in Italy they still practice as in other countries..
"The paper recycling (Science and Technology Laboratory, 1G).
The problem of pollution due to paper recycling exists throughout the world. In fact, many items that are purchased are wrapped with paper or cardboard.
Paper is a material made of fibrous materials and, depending on use, these are added dyes, mineral fillers , adhesives and other additives .
Paper is a hygroscopic material and is made from cellulose derived from tall trees from forests now threatened with extinction. The paper is one of the most polluting, there are about Earth and accounts for 35% of municipal waste worldwide. And 'Well, then, to follow the rules to reduce pollution
1) Save boxes: our purchases, for the most part, are contained in cardboard boxes. Do not throw away because we could reuse for wrapping gifts or for removals.
2) Recycle mail : When we receive flyers, mail is not acceptable, do not throw him into the garbage, because 99% of it is recyclable paper and can be useful if we throw in the bins provided.
3) Paying bills online : now you do everything on the internet, it is possible to recharge the phone, pay bills and taxes.
4) Print on both sides: we must not only print on one side of the sheet of paper, but on both sides, so we save 50% of paper.
5) Buy recycled paper: saves the lives of hundreds of trees, acres.
6) Do not for a subscription to the library to photocopy the book
7) the telephone directory Recycle: Do not hold the telephone directory yellow pages and throw them in the closet but in the box provided. San

"Paper ( Science and Technology Laboratory, 1G)
China was an inventor, using old rags, who managed to produce a material suitable for writing. The technique spread to Spain. paper produced from cellulose has the fibrous component that is extracted from the trees. It 'a substance that has a hardness and rigidity. In addition to cellulose can be used for paper making, rice, flax, cotton, silk, cloth, corn, hops, algae and other natural materials. When the paper has no consistency can be used as fuel to produce energy. Paper is a material that has a good calorific value. To produce a piece of paper it takes 3 months working . Paper should be recycled in 'suitable housing..
"Reflections on the hunt ...
Leo, 1G: According to me the hunt is not as destructive as you think, but rather a way to keep the animal population under control, such as wild boar destroying the crops of corn and salad, while the wolves eat their livestock: sheep, goats, chickens and sheep, etc.. The foxes eat chickens and crows, which are fond of corn and small animals.
Lor, 1G: I AM ONE OF THE MANY, HOWEVER, CONTRARY TO HUNT. One reason is' THE FOLLOWING: The Earth is warming with the greenhouse effect and many species of animals are endangered, especially the animals that live in the cold as bears, wild boars, foxes and many others.
A SECOND REASON FOR NOT hunting and 'that animals are living beings like us is, in my opinion, have feelings. For example, are very scared and shocked by the hunters..
In 1G are conflicting views on hunting, while the prevailing opinions totally opposed to this practice. And 'well, however, noted that' objective Primary future generations will be to preserve the BIODIVERSITY ' , threatened predatory attitude with which the human species is doing to the environment.
GLOBAL WARMING AND ITS CONSEQUENCES
"Most scholars who deal with the problem expected that the increase of carbon dioxide in Earth's atmosphere will lead to an increase in future years global average temperature. With regard to the increased precipitation is expected to be significant in the northern hemisphere in terms of increased concentration at certain times of the 'year, there will be a reduction of rainfall in the tropics and subtropics. Again, it is reasonable to expect a increased frequency of extreme weather events as floods, torrential rains, storms and heat waves and extreme cold, an increased risk of desertification in temperate zones, a decrease of glaciers in the world's most important mountain ranges, and finally a average sea level rise (in the last 100 years have witnessed an increase of 10.25 cm)..

LIGHT POLLUTION
"The starry night sky is no longer what it once was, as the film in town is precluded because of light pollution. The Italian Parliament approved a text against the 'Light pollution: in fact the area was always changed from' man who has a positive effect when it improves the quality of his life, negative if it worse. The most significant negative effects they have in Europe's most populated areas , because 'man has safeguarded the area but thought only to economic development. To repair the damage must make a development compatible with the environment and reclaim degraded environments.

"Light pollution is due to ' irradiation of artificial light into the sky, when the artificial light affects the atmosphere and the particles are transformed into brightness sky. This results in a low light: stars, planets, etc.. The problem is astronomical because it makes less efficient use of the instruments used in observation. Increasing the brightness of the night sky can alter the rhythms as the biological sleep, etc. photosynthesis. This form of pollution is increasing. Compared to the past, it is estimated that the brightness of the sky four times..

"The geography and ecology address topics relating to the environment. This must be respected by humans to improve their civil society. But most importantly of all, in addition to the familiar arguments, you know how to put into practice.
global pollution is the set of all types of pollution that we see every day and produce. The night sky is polluted by street light pollution.
Because of this, the night, instead of seeing a beautiful starry sky, we can only observe the yellowish-gray clouds that cover the vision of stars and planets.. Mill96
" How to reduce pollution
Industries could use clean energy sources. In town we install heating systems are cleaner and take action on the road in traffic, which increases the amount of electric vehicles.
Each of us could help by:
-using public transport
-checking the quality of the gas in your vehicle;
non-working spray cans that damage the ozone layer;
-recyclable waste disposal in your household.

"Technology today is one of the causes of environmental disasters, but also invented of sophisticated monitoring tools to detect pollution of the Earth .
For example, in major cities have installed the units that monitor the air pollution. In addition to these there are also tools that analyze samples of soil pollution. We must first know the causes of and formulate possible depending on the problem solutions.. Mill96, Giudy96
Biodiversity " to biodiversity is the sum of all forms of animals and plants, genetically diverse on Earth and its ecosystems. The importance of biodiversity lies in the fact that life on earth, including humans, it is possible mainly thanks to ecosystems. Biological diversity is the key to the functioning of the ecosystem earth and is considered not only the diversity of existing species and subspecies, but genetic diversity and ecosystem diversity. The loss of species, subspecies and imposes a variety: ecological damage and a degradation of ecosystem functions; cultural damage, or you lose the human knowledge related to biodiversity; economic damage because it reduces the potential genetic resources.. me., 1G
BIODIVERSITA'2 "Although we are part of biodiversity and use the services that we offer: food, water, energy and resources to our everyday lives. It is a universal heritage for all humanity and for this store must become our priority. Biodiversity therefore is understood as the richness of life on earth. All life depends on biodiversity on the planet, which is why we need to reduce the extinction of some species of animals and plants.. And hello

BIOBUILDING : energy efficiency homes. The traditional housing (small percentage) is responsible for the pollution and excessive energy consumption. The green building is to improve the quality of buildings to improve the quality of life and 'environment, using natural materials and recyclable through systems and installation of high efficiency and low consumption. Energy saving is achieved, for example, thanks to ' insulation of the roof and exterior walls, installing insulation panels behind radiators, installing new seals on windows and double glazing ; insulation of pipes carrying hot water, installing thermostatic valves on radiators and a thermostat.

SUSTAINABLE DEVELOPMENT. " To ensure that the various types of pollution do not cause serious damage to nature, we should achieve sustainable development by man, that use of resources in a moderate way, reduce the production of waste and recycle what nature can not dispose . To enable this you should do a lot of investment. The EU has always supported sustainable development and since 1972 has encouraged countries to join this project, using, for example, alternative energy sources or by creating environmentally friendly materials or substances. In 1996 The EU has carried out checks on industries, tourism, transport, energy and agriculture. He also secured places natural as brugherio Belgian, the coasts of Britain, the dry places of Sardinia and the marshes of Finland. In 1993, the EU established the EUROPEAN AGENCY FOR THE ENVIRONMENT for the enactment of laws against pollution, based in Copenhagen. In Italy there were many laws on the environment as in 1996, the anti-smog laws in order to moderate the use of household and industrial gas, in 1976 the Merli law for the control and water purification and in 1985 the law against Galasso pollution of the landscape. Unfortunately, many laws continue to be waived..
