Monarch butterflies are pollinators. They pollinate many different plants. Without the monarchs, we would be without a lot of crops like tomatoes and melons. The whole food chain would be messed up without monarchs.
The monarch population used to be up in the billions. But in the last two decades, the monarch population has declined by 90 percent. Populations have been changing frequently in many species of animals. But the monarch population has been decreasing at a constant rate. This should raise quite a few red flags. Why has there been such a decline in the monarch population? Mostly, it’s due to the decline in milkweed. When droughts occur in the south, they take out a good portion of the plants. Some pesticides used for farming kill milkweed. Thus, taking away food from monarch caterpillars, room to lay eggs, and safe places for the chrysalis process. The monarchs are dying.
