There has been much controversy on immunizing children • (vaccinating them), especially in regards to autism. This has led to the reappearance of sometimes deadly diseases, such as measles and mumps. what is your opinion? should children be vaccinated against diseases or not?

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
