(Rajagopal, Zilberman, 2007). Nevertheless, there are many uncertainties around the biofuels' carbon neutrality. In the production process, biofuel require significant amounts of energy for tillage, fertilizers, pesticides, irrigation and for harvesting. Nitrogen oxide from fertilisers are known to be particularly potent greenhouse gases with 300 times more potential than CO 2 and it has a harmful effect on the stratospheric ozone (Schaerlmann, Laurence, 2008). Also, as in any other agricultural production, biofuels can cause erosion and eutrophication due to fertilizer runoffs (Rajagopal, Zilberman, 2007). According to the International Energy Agency Report (2007), the fossil energy balance for different biofuels varies greatly, depending on the feedstock productivity, production and conversion technologies.

"(E.Kyrö, 1993, lk 3,4) 1991 aastal Colorado ülikoolis koostatud arvutimudel viitas kolmandiku osooni kadumisele Antarktika kohal. See muutis tõsiseks nii atmosfäärifüüsikute kui ka poliitikute suhtumise. Tõsist tähelepanu hakati p öörama varasematele mõõtesarjadele. E.Kyrö(1993) andmeil leiti kõigist umbes 40-st Antarktikas asuvast uurimisjaamast üle 30 aasta pikkusi vaatlussarju, kus oli selgelt näha osoonikihi olukorra pikaajaline muu tus. Kävitati EASOE (European Arctic Stratospheric Ozone Experiment), milles osaleb 250 uurijat 17 erinevast riigist. Nende käsutuses on 3 erilennukit. Umbes 50 piimvalget õhupalli tõstavad igaüks 40 kg mõõteriistu kuni 35 km kõrgusele(seal on pallide kubatuur 100000 kuupmeetrit). Põhja Rootsist Kirunast startisid geofüüsikalised uurimisregatid. Kokku kulutatakse projektile EASOE 40 miljonit DEM-i. E.Kyrö(1993) andmeil kestis EASOE pr ojekt 1991-1992. M.Kannineni ja P
over the cross-ruled paper on his desk, would glimpse the skeleton of a pattern in a few scattered letters; he tried fitting a fragment from another recovery into it; he tested the new values that resulted and found that they produced acceptable plaintext; he incorporated his essay into the over-all solution and pressed on. Experts in Japanese filled in missing letters; mathematicians tied in one cycle with another and both to the tables. Every weapon of cryptanalytic science—which in the stratospheric realm of this solution drew heavily upon mathematics, using group theory, congruences, Poisson distributions—was thrown into the fray. Eventually the solution reached the point where the cryptanalysts had a pretty good pencil-and-paper analog of the PURPLE machine. S.I.S. then constructed a mechanism that would do automatically what the cryptanalysts could do manually with their tables and cycles. They assembled it out of ordinary hardware and easily available pieces of
