Industrial forest plantations are not forests, denounce environmental activists

Leave a Comment
LPN, GEOTA, GAIA, FAPAS, rock, Oikos, Quercus and SPEA have been organizations that rallied today, world day of forests, to assert that the forests are multidimensional systems that combine the structural, functional and biological diversity. This definition includes elements not ferns such as soil, water, microorganisms, fauna and flora and the interaction between species and human communities.

According to the statement sent by the "industrial short rotation crops in monoculture regime are nothing of this and this confusion only serves to harm the forests".

These organizations argue that the various initiatives that are taking place during the day, across the country and around the world, "deserve clarification that many celebrated forests are not in fact".

The proliferation of forest plants for the industrial exploitation does not reverse deforestation. On the contrary, it has contributed to the replacement of ecosystems and biomes rich and complex, as are the forests, for authentic "green deserts", i.e. plantations of Palm, eucalyptus, Acacias or rubber trees, among other monocultures.

"A forest is often the most advanced step in relation to the potential balance of an ecosystem. A forest plantation monoespecífica is a basic and eco-system too lean ", clarifies the statement.

For the loss of the richest forest areas all over the world have contributed and pernicious use of the idea that eucalyptus or acaciais are effectively forests.

In Portugal, although they point to a large forest area, the truth is that plantations of eucalyptus and pine forests, in particular when used in very short rotations schemes for maximum extraction of raw materials, have led to serious environmental, social and economic problems.

One of the proofs is the destruction of biomes such as savannas or grasslands, now occupied by forest plantations with little or no contribution to local economies and to the balance of ecological, biological systems, hydraulic and soil.

Kiss giraffe keeper suffering from terminal illness

Leave a Comment
These are the photos that depict the exciting moment when a giraffe bids farewell to the keeper of several years, who suffers from terminal cancer. The groom, of 54 years, spent most of his life taking care of giraffes at the Zoo Diergaarde Blijdrop in Rotterdam.

The handler, only known by Mário, asked his hospital bed was transported into the giraffe cage so that he could see the animals one last time. One of the animals approached then handler's bed and gave him a kiss goodbye, referred to the Dutch press.

"These animals have recognized it and felt that things weren't right," asserts Kees Veldboer, founder of Ambulance Wish Foundation â€" an association that is dedicated to fulfill the last wishes of terminally ill-treater's bed that transported to the zoo.

Mario, who had a mental deficiency, may also fire if the coworkers of the zoo, where he worked for almost 25 years.

Why is Paris so polluted?

Leave a Comment
Last week, Parisians have experienced moments that no longer lived for several decades, all of them with a very specific objective: combating pollution. Thus, public transport were free for three days, and the cars just might carry over every other day, depending on their license plates.

Now that the air becomes more breathable, want to read about an old controversy to justify the pollution of Paris â€" subsidies to diesel. According to Le Monde, this pollution is "a reflection of 20 years of inertia of France, that falls on everyone ... and the car industry lobby, which covers drivers, operating system, manufacturers of diesel-powered vehicles, which have stifled the debate on legislation".

According to the French newspaper, Paris is more prone to pollution than other European capitals because of subsidies to diesel, which produces seven times more harmful pollutants than gasoline.

The love story of France with diesel come a long way. A report in the website Huffington Post explains that she date of rural economic stimulus policies of the postwar period, implemented by Governments.

The measures sought to encourage the recovery of the field (about half of the French population lived in rural areas at that time), making diesel for agricultural machinery and trucks cheaply. Taxes and fuel taxes were reduced and continue to be facilitated even today. To give an idea, the reduction of taxes on diesel cost the French economy nearly € 8 billion in 2011 (about US $ 26 billion).

In 2011, diesel cars accounted for 70% of car sales in France. In a city where 60% of the car fleet is moved to this fuel, is not to cause surprise the explosive framework resulting from the combination of local emissions of transport and a climate that prevents â€" or prevented â€" the dissipation of pollutants.

After a week of sunny days and cold nights, much of the Air France â€" and not just in Paris â€" has become a kind of toxic soup. The sudden change of temperature exacerbated the problem, creating a bubble that prevents the polluted air is dissipated. And the cause of everything, apparently, comes from behind â€" very rear.

Red squirrel back to Portugal after extinction of centuries

Leave a Comment
Hundreds of years after having been presumed extinct in Portugal, the red squirrel is returning to the country, after an expansion from Galicia, in Spain, in the years 80. In 2000, the animal was already distributed throughout the north country by the River Douro, and today there are already reports of Red squirrels almost to the Tagus River.

According to the biologist Rita Garcia Rocha, of the University of Aveiro (UA), nobody knows for sure, however, exactly where this species occurs. The biologist of the AU, which is studying the expansion of that species in the country, launches an appeal for them to be reported sightings of animals and traces of their presence: "If you see a squirrel be sure to tell us where you found it."  Records can be sent to the Facebook page.

The project, called red squirrel in Portugal, aims to "understand the expansion of the red squirrel in the national territory, what are the factors that influence this expansion and their behavior patterns", reveals the researcher.

In development in wildlife Unit of the Department of Biology of the AU, the project wants to still do the genetic characterization of the species for which, in the final set of results, show what the future of the squirrel in the national territory.

The biologist describes the squirrel as "a friendly rodent, with a very fuzzy tail and which can be sighted in Portuguese forests, mainly in the treetops. Despite its name red squirrel, the coloration varies from Brown to black completely ".

The biologist also asks for being reported indications of their presence, such as pinecones gnawed on the floor of forests, with a peculiar pattern, because the animals leave the scales from the top, forming a small Tuff, and are fairly easy to recognize.

Plants can generate sustainable energy as they grow

Leave a Comment
A Dutch start-up, Plant-and developed a way to use the plants as a continual source of clean energy â€" you only need a light source, carbon dioxide, water and plants.

When plants create their own food through photosynthesis, much of the organic matter generated is excreted into the soil through the roots. This matter is consumed by microorganisms that live in the soil. In turn, these microorganisms release electrons, as byproduct of this consumption. This start-up system consists of placing an electrode near the root system of the plants, which stores this wasted energy and converts it into electricity, referred to Inhabitat.

The process is similar to simple school experiences made with electricity, using apples or potatoes to create batteries. However, this system has the advantage of not harming plants, which continue to grow normally even in the presence of the electrodes, and can be, in this way, a constant source of energy, both day and night.

The system works best in damp or flooded land, as the rice fields, and it doesn't matter if the water use is polluted or has already been used. This factor allows improper areas to cultivation can be reused as an energy source. The system does not require the installation of elaborate infrastructure, which can allow carry electricity to isolated regions that are not served by mains.

Is already being tested in the Netherlands a prototype green roof that uses this technology. Currently, the Plant-and can produce enough energy to power a mobile phone, but the aim is that this method be used soon to collect a larger amount of energy â€" enough to power a home.

Leave a Comment
For nine days, from Saturday to March 30, the GuimarãeShopping will be the stage of the exhibition "recycling of Tetra Pak Packings", sensitizing visitors to the importance of this theme.

The exhibition aims to answer several questions, including: "do you know what are made the packaging normally used for the consumption of milk? And that destination must have once used? " The questions will be addressed by Tetra Pak.

Aimed at children and families, the initiative will be present on the Floor of 0 GuimarãeShopping, aiming to raise awareness of the importance of separation of cartons for liquid foods and for recycling after being deposited in the yellow recycling facility.

Visitors can try games, watching movies and participate in educational workshops â€" where recycling can learn how to build various objects from the material that composes the Tetra Pak packaging.

"With this exhibition we want to show visitors how the recycling of our packages and applaud the critical role that all play in this process, through the separation and placement of used packaging in yellow recycling bin», explains Ingrid Hawk, head of Tetra Pak ' s Environment in Portugal.

One of Tetra Pak ' s environmental targets for 2020 is to double to 40% recycling rate of their packaging. In this sense, the company focuses many of its efforts in awareness-raising activities of consumers.

EVOA: a haven for birdwatching on the outskirts of Lisbon

Leave a Comment
Flamingos, eagles, marrequinhas, fishing-geese, herons, warblers. In total, the estuary of the river Tagus is home to about 200 different species of birds. Was the natural wealth of the estuary itself that it has boosted the site as one of the most important meeting points, at national level, of migratory species.

Among this wealth of the Tagus estuary and the Lezíria de Vila Franca de Xira-where the Tagus and Sorraia converge, giving rise to the largest wetland of Portugal, was born at the end of 2012 a natural paradise for birds EVOA name (space of Visitation and birdwatching).

Celebrating a year of life, this space is assumed already as a place of excellence for birdwatching and for those who want to learn more about the biodiversity that exists in the region of greater Lisbon.

About 70 hectares, EVOA integrates three freshwater ponds â€" the main, the Shallow and Wide. In each of these wetlands that are strategically placed observation points of birds, although the animals can be observed from any point of booking.

Although the estuary receive 200 different bird species, not all pass through EVOA. According to Sandra P, Coordinator of the space, this last winter were accounted for approximately 14 thousand birds of 45 different species.

In addition to the birds, visitors can still find wild boars and foxes, which circulate freely by booking online. Also there were otters, but currently no animal of this species inhabits the place.

Dissemination through the "pass it on"

Since the opening in April of 2013, who have passed away by EVOA about 4,000 visitors, being that most visits occur between November and January, when there are more birds in the reserve due to winter migrations.

Visits can be made autonomously, but this mode is more advisable to observers and experienced photographers. For amateur observers a guided tour is the best option â€" there is no risk of losing the tracks and the identification of birds is facilitated by the help of guides.

The best time of day to visit is during the high tide, since the flow of the river and estuary birds on refuge in artificial ponds EVOA, allowing for better observation.

According to Sandra P, most visitors never made bird-watching before and is from Lisbon. "Maybe the inhabitants of Vila Franca do not appreciate so much space for are already in the lezíria", points to the Coordinator. Most who visit this paradise undisturbed in the middle of the lezíria goes into groups or families or in study tours offered by various educational institutions. "It is customary to see a person who came in group go back some time later with another different group. Works quite the wrong word ", indicates.

According to the Coordinator of the space, the objective is that the Center will receive between 10 to 15 thousand visitors annually within three years, which should promote the self-sustainability of the place.

In addition to the rails and strategic points of observation of the birds, the EVOA has an interpretive center where visitors reception is made. In the Center there is a permanent exhibition where visitors can get to know the different bird species and their characteristics, migration routes and a little of the history of the estuary and the lezíria. There is also an interactive space with games and movies.

In addition to visitors, the playful and components still gathers EVOA pedagogical, by performing and workshops and ateliers, both for families and for the schools.

The project was born of a protocol EVOA, initiated in 2007, between the breeze and the Companhia das Lezírias, owner of the land, under the programme for Biodiversity Breeze. The space cost three million, with the breeze contributed €1,3 million. The remaining funds came from the National Strategic reference framework. Later, also the Institute of nature conservation and forestry, city of Vila Franca, of Aquaves, the Association of the beneficiaries of the Lezíria Grande de Vila Franca de Xira and the League for nature protection joined the project.

Currently, the space is guaranteed by the Breeze and the Companhia das Lezírias until 2017, at which time it is anticipated that the space becomes self-sustaining.

The EVOA can be visited throughout the year, with prices ranging between € 6.6 and € 12. However, this year the space will be closed during July for maintenance of Rails, month in which there are fewer birds in the reserve.
