Scientists warn of DDT trap.
This is the view of NZ and internationally recognised soil scientists from Massey University, Dr Max Turner, a soil chemist, and Dr Neil Macgregor, a soil microbiologist. Less yield and higher costs of production for the GE crops was not good news. In the United States, already more than 10 million acres has been planted with GE crops, while research is just starting to assess the environmental risks of the technology. Broaden debate For New Zealand, Dr Turner said, the only answer to the GE conundrum was to broaden the debate and extend the research further from just food safety aspects into the wider implications for land use and soils. Most of the current interest is in health and food safety issues, but no one has taken into account that GE modified crops are likely to leave a genetic imprint on land on which they are grown.
