I\u2019m a big fan of the scientific method. …\u00a0\u00a0I also support the general principle of evidence-based policy.<\/em><\/p>\n Ma non siamo pi\u00f9 nel 1996:<\/p>\n \u00a0The global acreage of GM crops has grown consistently without broad acceptance from Europe. It is now topping out. Last year, it grew by only around 3%, according to industry figures, to 181\u00a0million hectares \u2014 a little more than one-tenth of the 1.5\u00a0billion hectares of land that the United Nations estimates to be under crop cultivation.<\/span><\/em> Quanto allo scontro sulle etichette:<\/p>\n Some critics still hope that universal labelling on food packaging means the beginning of the end for GM crops. More probably, it will mark the end of the beginning \u2014 if it prises out a fresh approach from the scientific community and the agricultural biotechnology industry to come clean with the public on what they\u2019re doing.<\/em><\/p>\n Interessanti anche i commenti…<\/p>\n Nelle news, c’\u00e8 la ricerca di Jo Clarke et al. su Current Biology<\/em><\/strong>.<\/em><\/a> Stando ai dati raccolti tra il 1978 e il 2013 la pesca pi\u00f9 devastante – calcolata in base alla quantit\u00e0 di pesce ributtata in mare – \u00e8 quella sotto i 600 m di profondit\u00e0 dove la biomassa \u00e8 pi\u00f9 abbondante.

We used a novel database, Global Naturalized Alien Flora (GloNAF), combined with data on the origins of the naturalized species and estimates of the numbers of native species per continent, to assess (1) which continents have accumulated the largest naturalized floras, and (2) which have been the major donors of naturalized alien plant species to other parts of the world.<\/em><\/p>\n Risultato:<\/p>\n Humans have strongly shaped the geographical composition and global distribution of alien plants among the World\u2019s continents, with the Northern Hemisphere being the major donor. The Pacific Islands and Australasia harbour the highest numbers of naturalized alien species, given their sizes and the extent of naturalization of species from other continents.<\/em><\/p>\n Il melting pot pi\u00f9 denso ed esteso si trova sulla costa orientale del Nord-America, pi\u00f9 accogliente verso gli immigrati umani – il che conferma un’intuizione di Darwin – ma ce n’\u00e8 uno anche in Giappone che invece li tratta malissimo.

\nFive-sixths of that GM acreage is in the Americas. The rest consists mostly of non-food crops (mainly cotton) grown in India and China. Little of the harvest is in nations that need improved yields to feed themselves. Twenty years in, the GM strains currently under cultivation are still best suited to the needs of large-scale industrial farmers who can afford the seeds and inputs that accompany them. Whatever Europe decides, the rest of the world isn\u2019t waiting to follow suit.<\/em><\/p>\n<\/p>\n
\n\u2022 The chemical compositions obtained for rainwater and HEPA air filter dust are only compared to chemical compositions obtained for coal-fly-ash leaching experiments. The author did not attempt to compare his results to chemical compositions of other potential sources. Thus, at this stage, the work is preliminary since it is not clear what the source of these chemicals is.<\/em><\/p>\n
