In their letter, UCCSNAL question the safety of CRISPR/Cas9 and other new biotechnologies as well as the influence of science in the decision-making process regarding the adoption of the new technologies. They fear that these technologies will further increase monopolistic powers over seeds, land grabbing and migration from the land and also have other, unanticipated impacts.

"The new technologies facilitate faster, more extensive changes in the genetic material of more organisms, and at lower cost", they argue. 

UCCSNAL demands a halt of all experimentation in this field. Rather, science should be based on acroecological techniques and local knowledges.
