Cross-pollinating super trees

The World Wide Fund for Nature says 116 GM tree trials have taken place since 1988 and these trees can cross pollinate with native trees over a distance of 400 miles. "Other GM modifications under trial raise the prospect of silent forests, devoid of insects, flowers and birds. The idea is to create super-trees that grow rapidly, resist rot, and defy insect attack. The trees would be sprayed from planes to kill all life around them."
