Ekologija in okoljevarstvo

[free]

Ekologíja je znanstvena veda, ki preučuje porazdelitev in bogastvo živih organizmov in odnose med živimi bitji ter živim in neživim okoljem.

 

Okolje organizma vsebuje njegovo fizično naravno bivališče (habitat), ki ga lahko opišemo z vsoto krajevnih samovzniklih dejavnikov kot sta podnebje in geologija in tudi drugih organizmov, ki si bivališče delijo. Pojasnjuje, kako živijo rastline in živali v povezavi druga z drugo, kako so odvisne od naravnih virov in dobrin (tla, voda, zrak, sončna svetloba). Preučuje prilagoditve življenjskim razmeram, kjer organizmi živijo. Znanstvenik, ki deluje na področju ekologije, je ekolog.

 

Kadar govorimo o konkretni vrsti ali drugem taksonu, pomeni ekologija skupek vseh interakcij tega taksona z živim in neživim okoljem, torej habitat, kjer lahko živi, njegovi plenilci, zajedavci, plen idr. V zadnjem času se izraz pogosto, a nekoliko neustrezno uporablja kot sopomenka za sorodno, a mnogo ožje področje okoljevarstva (oz. naravovarstva), ki obravnava človekovo prizadevanje za zmanjšanje lastnega škodljivega vpliva na okolje.

 

Sistemska ekologija - je področje ekologije, ki pri preučevanju povezav med različnimi prvinami ekoloških sistemov uporablja matematične metode. Sistemska ekologija se ukvarja z raziskovanjem preprostih sistemov (odnos plenilec - žrtev), kot tudi z raziskovanjem sestavljenih sistemov (raziskovanje pokrajin). Kadar se poslužuje matematičnih metod ustvarja modele ekoloških sistemov in preučuje različne medsebojne povezave sestavnih delov sistema. Analiza modelov omogoča določitev manjkajočih segmentov ekološke vede glede na modelirane sisteme, lahko pa tudi spodbuja in usmerja k natančnejšim raziskavam.

Ozonski plašč manjši za 13%

 

Ozonski plašč nad Arktiko se je pozimi zmanjšal za 13 odstotkov, kar ni slab rezultat glede na minulo desetletje, je sporočila Svetovna meteorološka organizacija (OMM). Luknja v ozonskem plašču je nad severnim tečajem zelo gibljiva, zaradi česar jo je težje raziskovati kot na ozonsko luknjo na južnem polu, navaja OMM.

 

Popolne obnove ozonskega plašča, ki ščiti Zemljo pred škodljivimi sončnimi ultravijoličnimi žarki in ki ga je onesnaževanje v 20. stoletju resno načelo, ne bo pred letom 2065, je sporočila organizacija, ki je doslej predvidevala, da se bo ozonski plašč obnovil do leta 2049. Uporaba večine kemičnih snovi, škodljivih za ozonski plašč, je prepovedana ali s protokolom iz Montreala iz leta 1989.

OCEANA - EUROPE

 

ILLEGAL MORROCAN DRIFTNETTERS

One hundred fifty Morrocan driftnetters fish illegally in the Alboran Sea and the Straits of Gibraltar. Oceana has filmed and photographed the activities of fishing vessels operating from the ports of Nador, Alhucemas and Tangiers. The Moroccan driftnetters are overfishing the stocks of swordfish and killing 15,000 dolphins, pilot whales, sperm whales and other cetaceans, as well as 100,000 sharks per year. =0&tx_pressrelease_pi1[showUid]=500]>>>

SHARKS AT RISK

Launching a report about the dangerous decline in shark populations caused by European fishing policy, the newly formed Shark Alliance expressed dismay at the European Parliament Fisheries Committee’s push for weaker restrictions on shark finning.

The report, entitled “Shark Alert: Revealing Europe’s Impact on Shark Populations,” details the depletion of European shark populations and threats to global populations as a result of European Union (EU) policy. Highlighting shark finning as a major and escalating threat, the Shark Alliance stresses that the EU finning ban is already fraught with loopholes and urgently needs tightening rather than weakening. =0&tx_pressrelease_pi1[showUid]=506]>>>

Chronic oil pollution

THE POLLUTION OF THE SEA from hydrocarbons (crude oil, fuel, petrol, oily waste, etc) is a global problem that entails between two and ten million tonnes of these products reaching the sea each year. Although the bulk of public attention is focused on the oil slicks caused by major oil tanker accidents, chronic dumping of these substances – in other words, the residue from ordinary maritime traffic – is three times higher.

Washing out the tanks of oil tankers, dumping bilge water and minor spillages on board or in port are the main sources of hydrocarbon pollution of marine origin.

Read more about illegal oil dumping >>

 

The other side of oil slicks

In December of 2003, Oceana Europe made a splash by exposing the routine illegal dumping practiced by most tankers and transport ships. Every year, the European community learned, three times more oil is intentionally poured into the ocean during routine (but illegal) cleaning procedures than is spilled in accidents like the Prestige disaster.

Update: EU Parliament approves oil dumping sanctions!

A year and a half after Oceana began its intensive advocacy effort, the EU Parliament voted to approve strict sanctions for violators of oil dumping laws... (or some such text here. needs to be rewritten.)

Preventing 20,000,000 Tons of Oil from Being Illegally Dumped in the Ocean.

After advocacy work in Europe on pollution from ships, Oceana is very pleased that a new law was passed by the European Union that imposes criminal sanctions, including heavy fines and even jail terms, for the owners, operators and financiers of boats that illegally dump oily waters and residues into the sea. The new law could prevent as much as 20 000 000 tonnes of these polluting substances from getting into the ocean every year – the single biggest reduction in oil pollution in decades, anywhere in the world.

The Bialowieza Forest situated on the border of Poland and Belarus is the last remaining natural lowland forest in Europe.

It is abundant in wildlife, especially on the Polish side, and is home to lynxes, wolves as well as European bison whose history is closely related to the struggle for the conservation of the forest.

Take action now and help save Europe's oldest lowland forest

Unfortunately, the natural wealth and reputation of this unique place have not ensured its effective protection, with only 17% of the Polish area protected as a national park. The rest is subject to the logging of old trees – an enormous threat to the natural harmony of the forest and the survival of its wildlife.

If this exploitation continues it soon may be too late! Help us save this truly special place by signing our petition demanding that the national park is extended to cover the whole area of the Bialowieza Forest in Poland.

 

Sincerely,

WWF International

Time to get serious in Nairobi

To coincide with the critical UN climate talks taking place next month in Nairobi, demonstrations will be held around the world on Saturday 4 November to demand that world leaders take urgent action to tackle global warming.

Governments are meeting in Kenya to discuss what happens when the first phase of the Kyoto Protocol ends in 2012. If we are to slow climate change before it becomes too dangerous they need to commit to make deeper cuts in emissions. Find out how you can get involved in your country

Latin America - Up in Smoke?

Climate change impacts are being felt across Latin America, ranging from drought in the Amazon to floods in Haiti; from vanishing glaciers in Colombia to hurricanes, not only in Central America but even in southern Brazil.

Across the region the capacity of natural ecosystems to act as buffers against extreme weather events are being undermined, leaving people more vulnerable. [/color]Find out more

 

 

Climate ChangeInsurers looking to ensure their future

The insurance industry needs to do more to address the growing impact of climate change-induced damages, according to a new report by WWF and the Allianz Group, one of the world's largest insurance providers.

It examines the latest scientific findings about climate change, including the impacts of forest fires, storms and floods, and the potential impact on the insurance industry and its customers. Find out more

 

 

One thing you can do today to fight global warming... Switch to renewable energy!

Conventional electricity generation produces huge levels of carbon dioxide emissions - the principal cause of climate change.

So you can make a real difference by buying non-polluting green electricity from your electricity supplier. And if they don't sell it, you can change to a supplier that does!

Film Neprijetna resnica

 

http://blogs.chron.com/sciguy/archives/inconvenientruthonesheet.jpg

 

Premiera filma bo 19. oktobra 2006 v Kinoklubu Vič,

od 26. oktobra pa ga bodo predavajali v Koloseju.

Film se bo predvajal od 19. oktobra 2006 v Ljubljani, Mariboru in Celju, od 30. novembra pa v Kopru.

 

Za točen spored predvajanja filma lahko obiščete spletno stran www.kolosej.si (Ljubljana, Maribor, Celje, Koper) in http://www.planet-tus.com/ (Maribor in Celje).

 

Umanotera, Slovenska fundacija za trajnostni razvoj, sodeluje pri promociji filma Neprijetna resnica (An incovenient truth) zaradi njegove močne vsebine o podnebnih spremembah, na katere že dalj časa opozarjamo.

 

 

Film Neprijetna resnica tudi v Slovenijo prinaša dve osrednji sporočili :

 

• Segrevanje ozračja je dokazan pojav, ki ga povzroča človeštvo.

• Vlade in vsi prebivalci planeta se morajo takoj začeti boriti proti podnebnim spremembam in segrevanju ozračja: v 10 letih bomo dosegli točko brez povratka, ko ne bomo mogli ničesar več storiti in bo naš planet dolgoročno nepovratno poškodovan.

Umanotera sodeluje pri promociji filma Neprijetna resnica (An incovenient truth) zaradi njegove močne vsebine o podnebnih spremembah, ki jih čutimo že danes. In kaj nam napovedujejo strokovnjaki?

 

Človek ima samo še deset let časa, da se korenito začne boriti proti podnebnim spremembam, saj bomo po tem času dosegli točko brez povratka, ko bo Zemlja trajno uničena. Slovenec v povprečju prispeva 10 ton emisij CO 2 na leto, znanstveniki pa ocenjujejo, da je emisija na prebivalca Slovenije, ki bi bila pogoj za stabilno ravnovesje podnebja, okrog 2 toni CO 2 na leto...

 

 

Prispevek Slovenca k podnebnim spremembam je v povprečju 9 t CO2 emisij/leto. Znanstveniki ocenjujejo, da je emisija na prebivalca Slovenije, ki bi bila pogoj za stabilno ravnovesje podnebja okrog 2 t/leto. Izračunaj svoj CO2 odtis!

 

 

 

Klimatski profili županskih kandidatkov

Namen projekta izdelave klimatskih profilov županskih kandidatov je bilo preveriti, ali se županski kandidati zavedajo pereče problematike podnebnih sprememb, kakšne programe predlagajo na to temo in za kakšne cilje zmanjševanja emisij toplogrednih plinov se bodo zavzemali do leta 2020.

Hans-Josef Fell: Le obnovljivi viri energije lahko zadostijo energetskim potrebam človeštva

 

Naftna in premogovniška podjetja iz strahu za svoje profite zavirajo razvoj obnovljivih virov energije - Potrebujemo le nekaj velikih narodov, ki bodo razvili nove tehnologije

Promotor uporabe obnovljivih virov energije je nemški poslanec Zelenih Hans-Josef Fell, ki pravi, da lahko obnovljivi viri energije edini zadostijo svetovnim potrebam, primarni energenti so zastonj, cena tehnologije pada. Ustvarjajo tudi nova delovna mesta, v Nemčiji naj bi v tem sektorju v 15 letih dobili pol milijona novih delovnih mest, so zanesljivi in stroškovno učinkoviti, predvsem pa ne obremenjujejo okolja. Fell sam si je pred 15 leti zgradil hišo, ki vsako leto ustvari 1600 kilovatnih ur presežne energije. To usmeri v električno omrežje in prispeva k zmanjšanju potreb po fosilnih gorivih. Za osebne poti uporablja avto, ki ga poganja električna energija iz sončnih celic.
