Αναστάσιος Βελιγράδης
Πηγαίνοντας στο 1ο Γυμνάσιο Σερρών δεν περίμενα αυτό που βρήκα μπροστά μου και η αλήθεια είναι ότι ενθουσιάστηκα με τον τρόπο που μπορώ να βοηθήσω. Σαν απλός νέος, σαν εθελοντής της Πράξης, σαν Αναστάσιος Βελιγράδης μου ήταν σχεδόν αδιανόητο να βρώ τέτοιου είδους αρχείο. Για να ξεκινήσω απο την αρχή επισκεφτήκαμε το σχολείο με τον Bjarne, ο οποίος είναι ένας άλλος εθελοντής, με στόχο να συζητήσουμε με την Κυρία Σοφία για το πώς θα δημιουργηθεί ένα Blog στο ίντερνετ. Σε αυτό θα αρχειοθετήσουμε όλα τα αρχεία όλων των σχολείων του Νομού Σερρών, τα οποία είναι στοιβαγμένα σε συρτάρια και ντουλάπες, ουτώς ώστε να είναι εύκολα προσβάσιμα για τους χρήστες του ίντερνετ. Στην ουσία αυτή η δουλεία προσφέρει πολλά κέρδη στην κοινωνία διότι απο την μια πλευρά μπορούνε οι πρώην μαθητές των σχολείων να βρούνε τις δραστηριότητες που έκαναν στο παρελθόν. Απο την άλλη είναι εύκολο για εξωσχολικούς αλλά και νύν μαθητές των σχολείων να δούνε με ποία πράγματα ασχολήθηκαν οι προηγούμενες γενιές αλλά και να πάρουνε κάποιες ιδέες και να επεκετίνουνε τις γνώσεις τους. Προσωπικά μπορώ να πω οτι πρίν μπώ στην αίθουσα με τα αρχεία δεν πίστευα ότι γίνεται τέτοιου είδους δουλειά και στην Ελλάδα. Θεωρούσα πως δεν γίνονται δραστηριότητες και ότι γενικότερα το σχολικό σύστημα έχει μόνο λάθη και δεν υπάρχει τίποτα το σωστό. Ευτυχώς ο ισχυρισμός μου ήταν λανθασμένος και βρήκα μια ευχάριστη έκπληξη μπροστά μου. Αυτή η έκπληξη μου έδωσε δύναμη και όρεξη να δουλέψω για να στήσουμε μια ιστοσελίδα, μου έδωσε να καταλάβω ότι μπορώ να βοηθήσω και εγω κάπου και ότι υπάρχει ελπίδα για αυτή την χώρα. Θέλω να επισημάνω ότι τίποτα δεν μας χαρίζεται και ότι δουλεύοντας σκληρά και συλλογικά μπορούμε να πετύχουμε απίστευτα πράγματα, τα οποία δεν ονειρευόμαστε ούτε στα πιο μεγάλα μας όνειρα. Κάθε βήμα που κάνουμε μας φέρνει λίγο πιο κοντά στον στόχο μας, μας αναβαθμίζει σαν ανθρώπους και μας δίνει δύναμη να κάνουμε τα επόμενα βήματα. Μόνο έτσι μπορούμε να πετύχουμε τους στόχους μας και πίστεψε με μπορούμε! Ονειρέψου γιατί ΜΠΟΡΟΥΜΕ!
Αναστάσιος Βελιγράδης According to an UN report, the ozone layer, which procets the Earth from UV radiation, is healing. The ozone layer is a protective blanket of gas that shields us from harmful UV radiation emitted by the Sun. It started to become thinner during the 1970s and in 1985 scientists spotted a seasonal hole over Antarctica, prompting governments to start taking action to prevent further decline. It’s known that gases such as CFCs (chlorofluorocarbons) and halons, which were commonly used in products such as refrigerators and aerosols, can accelerate the depletion of ozone in the Earth’s stratosphere, so scientists and politicians across the globe put their heads together in a bid to reduce their use. In 1987, countries all around the world agreed on the Montreal Protocol to subtract these harmful subtances from industrial production and replace them with others. The impact of the Convention is examined every four years at a conference that was held this time in Equador. As a result of this, the ozone layer can be completely restored above the northern hemisphere by 2030, and the ozone hole may disappear from the top of Antartica in 2060. The ozone layer over the southern hemisphere can be healed by the middle of the century. It was said at a Quito conference. Paul Newman, leading Earth Scientist at NASA’S Goddard Space Flight Center, noted that if we had continued to emit ozone-depleting subtances to the atmosphere, it would have had a serious consequences, however we succeded to stop that. Without these serious measures the 2/3 of the ozone layer could have been destroyed by 2065. This year the size of the ozone hole above the southern hemisphere was almost 25 million square kilometer meanwhile in 2006 it was 30 million square kilometer. We reached points in time when the emission was increasing again, but in overall, it’s decreasing, fortunately. This report also noted that chlorofluorocarbons-emission growth has been measured in East Asia, where CFC gases have been forbidden since 2012, although the emissive country or countries has/have no been identified. Scientists are saying that it’s not yet a complete success story, we only reached that point where the healing process can start. According to Newman, it is not possible to report total success before 2060, as he said, "it will be up to our grandchildren to do it." Without the Montreal Protocol, it is estimated that atmospheric levels of these gases could have increased tenfold by 2050. Furthermore, according to the UNEP, the protocol will have prevented some two million cases of skin cancer annually by 2030, alongside protecting wildlife and agriculture. Personally it was thrilling to read these information because nowadays we hear so much bad about environmental issues that we have to face, finally it was something good that we have achieved by global collaboration. My other reason was that when I was younger, when we started to have environment classes in primary school this was the first big problem that I got to know about. Now as I recall I haven’t really heard news about it, this was the first after a lot of time that I read something regarding to this topic and I am really happy about it. Hopefully, this will contribute to the fight against the global warming, as the hole becoming smaller and smaller and the layer becoming thicker it can protect the Earth more effectively from the Sun. On one hand we are on the right track to tackle one huge problem that contributes to the global warming on some level, but on the other hand those subtances that we use now to avoid damaging the ozone layer are causing the global warming. Anyway this is huge success, just imaging what could have happaned to the nature, wildlife, how many lives were saved from getting cancer and danger of food supply because of the agricultural damage was eliminated this way. At least from the aspect. It gives us hope for other problems. Written by Edina Szathmári Sources:
Last year, the ZEvent raised 450,000 euros for a charity association “la Croix Rouge” after the 2018 edition, 1 million euros were raised for the benefit of “Médecins Sans Frontières”.
For the occasion, 40 french streamers took turns for 50 hours live the 9-10 and 11 November on the streaming platform named Twitch. We could count on Zerator, the creator of the event obviously, but also lot of famous streamers. The instigator of the project, Zerator, was able to count on a fairly complete press coverage, with a passage on the national radio NRJ tonight. But at midnight, while the pot was 830 000 euros, the donations arrived massively, and in the space of fifteen minutes, it is 150 000 euros. Not less than 280,000 viewers watched the event on average, on all streams and the total of the donation are reach the million of euro for "Médecins sans frontière" only with the donation. They also sale a t-shirt for an amount of 140 000 euros. Médecins Sans Frontières tweeted soon after, thanking all the users for their donations:

In my opinion it should be the absolute maxime of any scientist to dedicate their research to the well being of all people, to peace and sustainability.For that cause the World Science Day for Peace and Development was declared by UNESCO in 2001 and it is celebrated yearly on the 10th of October. The day promotes the peaceful use of science and the solidarity and cooperation of international scientific communities. Furthermore it attempts to strengthen the interest of the public in current scientific developments and their implications for peace and sustainability. This year the World Science Day for Peace and Development stands under the motto of “Science A Human Right” to further celebrate the 70th anniversary of the Universal Declaration of Human Rights. A special focus is layed upon the 27th article of the Universal Declaration of Human Rights, witch declares that every human has the right to participate in scientific development and protects the author of any scientific development. Another focus is to further develop and ease the access to education and science especially for girls, in order to make the current and all future scientific advances available and beneficiary to all humans. -Bjarne Hundt International Day for Preventing the Exploitation of the Environment in War and Armed Conflict6/11/2018 Considering the environmental damage caused by war conflicts, the United Nations General Assembly declared on November 6 each year as an international day for the prevention of environmental exploitation in war and armed conflict. One aspect that is often not duly taken in consideration in the study and analysis of conflicts is the fact that they, in addition to a human and economic catastrophe, are also an ecological disaster. Just think of the animals, the destroyed plants and woods, the polluted waterways and air, and the poisoned land. So, why is it important to disseminate this information in the community? Because the new generations represent the future of humanity and developing an awareness of respect for nature and the environment is important for preserving our planet. To get an idea about the devastation of the planet earth during the wars, we can refer to the Gulf War. According to the University of Kuwait, the pollutants dispersed by oil field fires during the Gulf War, in 1991, caused a tripling of cases of tumors in Kuwait and an increase in the incidence of neurological diseases, asthma and allergies. Pollution has also contaminated food, with 98 percent of the locally produced grain and milk now containing nickel and vanadium. Sea water salts to turn off the fires have incorporated heavy metals into metallic organic salts: in this form they are soluble in water and some are carcinogenic. "Vanadium, which can replace iron in hemoglobin, is particularly dangerous, as it inhibits numerous biological processes. The repercussions on the environment in terms of wars were already in the First World War with underground mines, but the negative effects of armed conflicts on the environment began to grow exponentially since the 1960s. In fact, since then, the weapons used are spread in the air and in the water without stopping at the borders of the individual States and have effects on health and the environment that we do not know well and that are destined to last. During the first Gulf War, in 1991, over 700 million liters of oil poured into the Persian Gulf. About 300 km of the coast of Kuwait and Saudi Arabia were covered with crude oil, resulting in damage to wetlands and swamps.Between 15,000 and 30,000 birds died as a direct result of this conflict and a high number of migratory birds perished as a result of oil contamination during transit in the area.Iraqis sabotaged about 600 oil wells, and as a result of the fires about half a billion tons of carbon dioxide were released into the atmosphere, causing air pollution even in India. Observing this aspect, we could say that preventing wars doesn't only mean protecting the civilian population from unnecessary massacres, but also means preserving the planet earth, avoiding permanent disasters. Written by Luigi Auriemma The word "tsunami" comprises the Japanese words"tsu" (meaning harbour) and "nami" (meaning wave.) Tsunamis are rare but devastating. A tsunami or tidal wave, also known as a seismic sea wave, is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake.
Over the past two decades, tsunamis caused almost 10 per cent of economis losses from disasters, causing slow development especially in countries that border the Pacific and Indian Oceans. World Tsunami Awareness Day is an opportunity to emphasize again the importance of disaster prevention and preparedness, including early warning, public education, science to better understand and predict tsunamis, and development that takes account of risk in seismic zones and exposed coastal areas. Like I wrote tsunamis are rare but extremly deadly. In the past decade, there were 58 tsunamis and they claimed more than 260,000 lives so it is an average of 4,600 per disaster. The tsunami that has the highest number of deaths in this period was in the Indian Ocean what was in december 4. It has 227,000 fatalities in 14 countries. Petra Kántor |
