Citalopram And Sleeping Lots

Gold Blue Dolphin, an increasingly 'precious

In part to climate change, but especially for the increasing world population, that of water and 'a problem that becomes more and more' dramatic, not because availability of 'theory, and in relation to distribution.

is estimated, in fact, currently being used maybe 30% of available water, but in this 30% are included as Iceland, which has 500 thousand cubic meters of water per capita per year, as well as' Canada, which has 20% of global water resources, as Egypt that, despite the Nile water has only a few cubic meters per capita per year.

The average requirement of water is estimated between 600 and 860 cubic meters per capita (from 1,600 to 2,400 gallons per day) but 'various international organizations consider the "shortage" a situation in which every resident has less than 1,000 cubic meters per 'year. Even more 'imbalances are also evident in respect of drinking water availability against a' day of 600 liters per capita in the United States and 200 in Europe, the people of Africa can only count on 40 liters, and even with them considerable differences country to country. Over the past twenty years the global need for water and 'increased by 40% and most of the increase and it' occurred in countries of the precious liquid already 'they had little, greatly exacerbating the difficulties' transport and distribution.

The impairment of the environment caused by industrial development is manifested not only in cases of frequent and deliberate pollution of waters and groundwater, even in deforestation, which leads shortage 'of rain in some areas and floods in other periodic and violent .

Our country and 'one of the most' high water in the world with 155 billion cubic meters per year, equivalent to 2,700 cubic meters per capita. Pero, 'irregularities' and inefficiencies flows reduce this willingness' to total 110 billion cubic meters and 2,000 cubic meters per capita. The availability 'is further reduced if we consider only fresh water (fresh water) term which means the water contains low concentrations of salts and other dissolved solids. In Italy the availability 'per head of the precious liquid and' lower than other major industrialized countries and also from different countries in the developing world.

In fact, the availability 'of water continues to decrease and for four months a year on 15% of the population, or about 8 million people, and' below the water needs at least 50 liters of water a day per person. This also because 'water and' output a myriad of agencies and other entities through 13 thousand water systems: one third of the available water is lost along networks often crumbling and corroded, enters the water pipes but is lost on the road. Even in many homes are made waste: taps and leaking pipes, water left to flow unnecessarily long, excessive waterings and then practically non-existent recycling and reuse of water.


To remedy this situation, it is in Italy as in the world, huge investments and especially the adoption of economic policies geared to the principle of charging consumers the real costs of water (very similar to what is happening already ' for gas and electricity). Altrettutto useful other strategies which would be a massive use of desalination plants from which to obtain water for agriculture as well as' the use of alternative and innovative irrigation systems to save water.

And then, there should not be surprised if in the coming decades was just the water to become an economic and even prominent political relations among nations and also within them. On the site

Altroconsumo lists the recommendations for the best use of the precious liquid and spend less on economic and environmental terms.

Squamous Metaplastic Cells

Ecotourism helps

Ecotourism , if properly regulated, can 'be very useful to nature.

It 's the result of a study published in Ecological Applications , the journal of the companies' American label. Through the pictures taken by tourists, an Australian researcher and 'able to "count" the people of the atoll a whale shark in Australia, and to monitor their health.

The Australian scientist began in '95 to study the huge sharks (known as "gentle giants") and found that the white spots along their sides and back are like "fingerprints" that allow us to distinguish one from 'else. With the help of an astronomer at NASA has adapted a program uses Hubble telescope to be able to recognize the different specimens. Submitting to the program more 'than five thousand photographs taken by tourists at Ningaloo, a marine park in Western Australia, the researcher and' failed to recognize many "old friends". At least two thirds of the sharks at Ningaloo returns season after season - explains the researcher - and this suggests that the population is increasing.
According to the researcher, the study confirms that the strict rules, designed to show ecotourists whale sharks, they have worked.

Oceans whale sharks as deserts

According to a satellite NASA surfaces marine biological death increased by 15%.
between water and land, deserts now cover 40 percent of the planet's surface.
~
was revealed in a study on the health of the oceans being published in the journal Geophysical Research Letters.
~
Viewed from space, the sea without life takes on a dark blue color, in contrast to the green chlorophyll of the areas in which the food chain prosper in peace. The paradox of the desert in the water is added to that of the planet became too blue, without which they draw sustenance from that green fish and cetaceans. The warming of surface water that blocks the movement currents and the exchange of nutrients between the layers of the ocean is not the discovery of today.
~
Over the past 9 years, deserts have expanded at a speed 10 times higher than expected. In Italian waters, the situation is even worse: "The extension of desert areas in the Tyrrhenian and the Adriatic is around 20 percent," said Silvio Greek, researcher ICRAM, Central Institute for Scientific and Technological Research Applied to sea. "The interruption of water flow acting on an ecosystem already compromised by over-fishing and pollution."

The lack of cold winters prevent the water surface to cool and then to sink to the lower layers of the oceans. Out of the depths, usually, is the warm water to rise, leading to the surface is rich in nutrients. The decomposition of marine organisms in fact fills the depths of salts such as nitrates and phosphates: substances that are in the depths be unused, while on the surface, combined heat and sunlight, to allow photosynthesis to trigger in some tiny single-celled algae. It is with the transformation of inorganic salts in organic elements such as beginning the phenomenon of life.
~
What happens on the ground with the chain of grass, herbivorous animals and carnivorous predators, repeat (Or at least should) in the oceans. In areas that appear green in the eyes of a satellite feed on unicellular algae living things bigger and more complex, up to whales. But at the heart of the great ocean, far from the mouths of the rivers that issue, however, some form of nutrient, even drugged by pollution, the NASA satellites every year have found more and more skimpy green areas. The absence of chlorophyll has sliced \u200b\u200bcleanly through the food chain, removing one after another all living species from the blue areas.
~
The extension of the deserts in the oceans - the study reveals - is linked to the increase in surface temperature. The phenomenon is spreading rapidly, especially in the North Atlantic. But no basin is saved, except the South Indian Ocean. Each year, on average, the blue area of \u200b\u200bthe desert grows to 800 thousand square kilometers. And to think that one of the strategies devised to combat the greenhouse effect consists in increasing its population of unicellular algae, casting iron and other nutrient salts in the ocean. Accelerating photosynthesis, in fact, scientists hope to increase the absorption of carbon dioxide by algae, cleaning up the atmosphere by greenhouse gases, which remains the number one suspect in the phenomenon of global warming. Increasingly convinced that the changes taking place are the work of man and his activities facilities are also scientists of the Geological Society of America.

Over the past two centuries, so deep were the scars inflicted upon the Earth and its atmosphere of our species, which U.S. geologists have proposed to rename the current was "Anthropocene" ages of man. Characterized by high concentrations of lead in air and water, a flood of carbon dioxide and other greenhouse gases in the atmosphere, rivers and dams that harness to prevent sediment flow into the sea of \u200b\u200bfertilizers, poor ocean of life and a more intense blue.
