Altieri and Peter Rosset University of California, Berkeley & Food First/Institute for Food and Development Policy Advocates of biotechnology affirm that the application of genetic engineering to develop transgenic crops will increase world agricultural productivity, enhance food security, and move agriculture away from a dependence on chemical inputs helping to reduce environmental problems. This paper challenges such assertions by first demystifying the Malthusian view that hunger is due to a gap between food production and human population growth.
Key words: biotechnology; transgenic crops; developing countries; Malthusian view; environmental risks. The effects of organic agriculture on biodiversity and abundance: a meta-analysis - BENGTSSON - 2005 - Journal of Applied Ecology.

The main negative impact on climate change is the emission of greenhouse gases (CO2, CH4, N2O), which is directly or indirectly due to the burning of non-renewable resources (carbon bound in mineral oil or coal). Tropical rainforests hold the biggest living biomass on very delicate soils that may lose their fertility completely when clear cutting is performed as in recent decades. Agriculture contributes to over 20 percent of global anthropogenic greenhouse gas emissions89 . Moreover, agricultural intensification has had major detrimental impacts on the terrestrial and aquatic ecosystems of the world. Organic Farming May Not Be As Beneficial As It Seems. Contrary to popular belief, organic farming may not necessarily be better for the environment. ... to According to a research study out of the United Kingdom's Oxford University, researchers have stated that organic farming has similar benefits as well as similar environmental impacts when compared to conventional farming.

ECONNECT - Supermarkety dovážejí mnoho biopotravin z ciziny. 22.6.2007BRNO [Hnutí Duha]Autor: Lenka Kaspříková, tel: 724 506 446 České supermarkety sice nabízejí stále více biopotravin z ekologického zemědělství – ale velkou část z nich dovážejí ze vzdálené ciziny.
Ukázal to podrobný dotazníkový průzkum, který dne 22. 6. publikuje Hnutí DUHA . Zelená organizace varovala, že domácí zemědělci zbytečně přicházejí o odbyt kvůli nedostatečné podpoře státu.

Biopotraviny jsou informačně velmi náročná komodita. Musíte spotřebiteli vysvětlit, čím se liší od konvenčních potravin, aby byl ochoten za ně zaplatit více. V okamžiku, kdy překonáme informační deficit českého spotřebitele, budou se biopotraviny prodávat lépe. Druhým problémem je zatím nízká koupěschopnost českých spotřebitelů, i když už dnes si biopotraviny kupují lidé, kteří nepatří do vyšších příjmových skupin. Třetím problémem je nedostatečný sortiment a dostupnost.
Kdy čekáte, že k nám přijde boom biopotravin? Rozmach trhu již začal. Biopotraviny a jejich boom. Potraviny, které dnes vídáme v mnoha regálech supermarketů, hypermarketů i menších prodejen, v blízké budoucnosti doplní ve větší míře ty ekologické, s označením BIO.
