Impacting the ecosystem!
The grasshopper can either impact our environment in a positive or negative way. they impact it in a positive way because since they're herbivore they link plants to the rest of the ecosystem. Dropping help by nutrient turnover, by returning nutrients as fertilizer for the plants. This provides food for birds, but also other arthropods. They can also affect our environment in a negative way by causing crop damage and loss of plants in pastures.
