The hazards of eucalyptus

1. Eucalyptus is a "water pump". Eucalyptus is a fast-growing and productive forest, which has a great demand for soil water. The introduction of eucalyptus trees in large areas will lead to a decline in the water table, and the ability to maintain water is very poor, and in the long run, the surface of the land will be crusted, and the phenomenon of land sanding will also occur.

2. Eucalyptus is a "fertilizer pump". Eucalyptus trees have a great demand for soil fertilizers and nutrients, which will result in a decline in land fertility, bad original vegetation, land degradation, deterioration of soil and water conservation, and infertility of the land.

3. Eucalyptus is a "bully tree". Eucalyptus is an "overbearing tree", and the ecology will suffer subversive damage, which is difficult to recover.

4. The chemical products applied to eucalyptus are highly toxic and have a long toxic effect, and eucalyptus gas has a stimulating and poisonous effect.
