Globalization, climate change responsible for outbreak of alien forest insects

An outbreak of mountain pine beetles in British Columbia is causing massive destruction of pines.

A new guide published by the Food and Agriculture Organization or FAO aims to help countries prevent pests from damaging forests.

At least 35 million hectares of forests are damaged by outbreaks of insects and pests each year.

In addition to globalization, global warming adds to the spread of forest pests.

Increases in summer temperature increase the reproduction of insects, while warmer winters improve their chances of surviving the cold.

According to the report, action on several fronts is needed to combat this threat of forest pests. This includes careful surveillance, management of forest, as well as transport operations.
