my hometown has many frogs, they are very benefit to our evrionment and agriculture.
for example, frogs eat pests,which means they can protect crops from damages. however, the number of frogs decreased gradually. there are some reasons cause this problem. firstly, their habitats loss.and secondly,some people prey on them.everyone konws frogs are so important for both nature and humans' life. so i think we have the responsibility to protect them.
