Watch and write slogans to protect frogs.

Frogs are protectors of crops and can catch pests. A frog can kill at least 30 pests a day, up to more than 200. If you kill a frog, it is equivalent to killing a chicken of a crop, and it is equivalent to letting thousands of pests escape and hurting crops more shamelessly. In order to eliminate pests in farmland, people often inject pesticides into farmland, leaving a lot of pesticides on crops. After eating these crops with pesticide residues, human beings have all kinds of health problems, which are the hazards of killing frogs. Frogs croak and it rains cats and dogs. In the evening of summer, as long as you hear frogs, it will rain heavily the next day. You are a veritable "weatherman". Frogs are our good friends, but some people kill frogs for money. I want to say to those people: stop killing frogs! Protecting frogs means protecting human beings!
