Uses of eucalyptus

It has been especially used to clean up wetlands to remove moisture from them with the consequent elimination of insect pests, especially mosquitoes, and the diseases they transmit.

Its use has been a great aid for malaria control in many areas in Asia, South America and southern Europe.

On the other hand, this capacity to absorb water, makes eucalyptus a species very aggressive to the environment by transforming ecosystems by drying the soil where they are planted.
