Numerous factors contribute to the ecosystem imbalance in Teresina, namely: the global warming and greenhouse effects, and pollution. Locally, some of the major causes are rapid urbanisation, disposal of toxic waste in water bodies, soil erosion, deforestation, agricultural practices among others.
The effects of this issue are becoming quite evident in Teresina through various events, mainly biodiversity loss, and insects, animals and plants infestation which in turn caused both marked public health problems and considerable socio-economic impacts.
