protect the frog500字
There are many kinds of frogs in my hometown.What makes them vital is that frogs are enemies of pest, which indirectly benefits farmers' crop. However, the number of frogs has been decreasing recently.There is no doubt that farmers' crop will be destroyed by the increasing pest soon if we take no messure to protect the frog.Therefore,we are bound to work together to prevent them from dying.First,we are expected to stop catching the frog and say no to all the food made from frogs.Second,please remember that don't pollute the environment.Otherwise,the frog will lose their habitat and can't adapt themselves to the surroundings，leading to their disappearance. In a word,no frogs,no crop.
