Some of the key points that challenge the claims that GM crops are safe, and/or necessary include:
* No scientific consensus exists about the safety of GM crops. A recent statement signed by over 90 international and independent scientists, refutes the existence of a consensus on the safety of GM crops. Some of the points they raise, are listed below.

* Statements made by international or scientific bodies about the purported safety of GM crops, carry considerable caveats, including dissent by well-established scientists within these organizations; conflict of interest by organizations that depend on industry or U.S. funding; and the fact that their assessments are based on data provided by industry itself, and not on independent research.

* A close inspection of scientific reviews; references made to lists of 'hundreds' of publications; and a citation of a long-term European study, all of which are often cited to claim proof of safety, reveals that these reviews are contradictory -- as many of the cited studies actually show harm, and that many of the cited references are irrelevant to the issue of human health risks.
* The claim that no one has been harmed from consuming GM crops, repeatedly made by industry and by support academics, is false, ludicrous, and irresponsible-- as NO epidemiological studies have been conducted on humans to determine the short- and long-term effects from our exposure to GM crops.
* Considerable research has been published in the literature, raising questions about environmental, social, and human health risks, from the production and exposure to GM crops. Despite claims by industry and by support academics that many of these studies have been 'discredited', no actual follow-up studies have been conducted to either refute or validate the experimental observations.
* Conflict of interest consistently obfuscates the claims of safety made by industry-affiliated scientists. Academic studies that receive support from industry are less likely to find adverse effects, while research by independent scientists is more likely to uncover adverse impacts.

What farmers need is concerted government and university support, to develop ecologically-based production systems. A new paradigm of sustainable agroecosystems is required, to meet community food security needs, and to satisfy the growing consumer demand for locally-grown, wholesome, toxic-free, and nutritious fruits and vegetables.
