Is tree water poisonous?

Eucalyptus is non-toxic, and so is the water around it.

Eucalyptus is a kind of green tree, but its growth rate is very fast and its ability of absorbing water and fertilizer is super strong, which leads to abnormal growth of crops around it. But it's nontoxic. Eucalyptus can be used to extract sesame oil, make paper, make furniture and fuel.

Eucalyptus is a fertilizer-loving crop. In order to promote its growth, sometimes a lot of fertilizer is applied, which has a certain impact on the surrounding water quality, but it is non-toxic.

Eucalyptus dispute:

Eucalyptus has been cultivated in western Guangdong for more than 50 years, and the export of processed wood chips has become a local pillar industry. So far, there is no report of environmental pollution caused by the release of toxins from eucalyptus. On the contrary, people also extract eucalyptus oil as a valuable spice.

20 14 in view of the problem of whether planting eucalyptus locally will pollute the water source, the relevant departments of Beihai randomly selected water samples from Niuweiling Reservoir and took them to the testing department for verification. The final verification report shows that the water quality indicators are normal.

Because eucalyptus forest is an artificial ecosystem and a pure forest with intensive cultivation, its biodiversity is certainly much simpler than that of natural ecosystem, but it will never reach the level of "nothing grows on the ground". One of the reasons for these criticisms is that we don't know enough about the characteristics of eucalyptus, and what really causes ecological damage is unscientific planting methods.
