In the EU legal system, there is a large difference between the proceduresand requirements for the introduction of crops that are classified as gen-etically modified (GM) and crops not so classified. In order to investigatewhether this regulatory divide is compatible with real risks two cases ofGM crops and two cases of non-GM crops are scrutinized. It is concludedthat the regulatory divide cannot be justified from the viewpoint of riskassessment, since the GM/non-GM dichotomy is not an accurate indicatorof either health risk or environmental risk. Much better such indicatorsare available and should form the basis of a legislation aimed at prevent-ing the introduction of crops that are harmful for human health or theenvironment. If the legislator has other reasons to regulate GM crops dif-ferently than conventional crops, then those reasons should be stated inthe legislation and determine the types of measures that it prescribe ; Mistra Biotech
The domestication of plants and animals is a long and on-going process that has shaped not only the domesticated species and the landscape, but also the humans who have domesticated them. For example, the evolution of our immune system has been strongly influenced by the close contact between humans and domestic animals. The changes in domesticated species have been dramatic, from the wild red junglefowl hen raising two clutches of 10 chicks per year, to today's laying hen producing more than 300 eggs per year. In one hundred years the average wheat yield has increased from two tonnes per hectare to six tonnes per hectare in many European countries. Although part of this increase is due to management techniques, fertilizers, and pesticides, the genetic component of such progress has been substantial. With an increased knowledge of evolution, the understanding of heredity, and the discovery of chromosomes and genes, we have gone from unintentional selection to advanced breeding programmes. Our ever-increasing knowledge of the mechanisms behind different traits can be used to customize the sources of our food. Thanks to these breeding programmes, we now have access to healthier livestock and crops, and are producing milk, meat, and grain at levels our ancestors could only have dreamed of. With this book we wish to provide an overview of the methods and techniques used in the domestication and development of new agricultural crop varieties and breeds of livestock. We also describe the legislation and discusses different ethical views on the use of biotechnology in crop and animal breeding. This book is published within the Mistra Biotech research programme, financed by the Swedish Foundation for Strategic Environmental Research (Mistra) and the Swedish University of Agricultural Sciences (SLU). This second edition is a shortened version of the previous edition. We are grateful to Inger Åhman and Marie Nyman for helpful comments on the manuscript.
You may not have thought about why tomatoes look the way they do, why our pets and farm animals are so calm and friendly, or how it is possible to get a watermelon without any seeds in it. Although the breeding of plants and livestock have shaped more or less everything we eat, few people know about the scientific achievements and the tedious work that results in the food we see on our plates every day. With this book we wish to give an overview of the background of domestication and breeding, from the beginning of farming more than 10,000 years ago to the molecular work of today. We present the basics of the structures and functions of genes, describe why and how different breeding methods are applied to crops and livestock, and give some insight into legislation surrounding the use of biotechnology in breeding in the EU and in Sweden. We also provide an overview of different products produced through genetic modification, a summary of the economic impact of such crops, and some ethical issues related to breeding in general and to genetic modification in particular.
