The U.S. Fish and Wildlife Service revealed that it is starting a status review of the Monarch butterfly population fallowing an appeal from conservation activist. The reevaluation will take-up a year and assess if the butterflies should list under the Endangered Species Act.
The popular colorful Monarchs are threatened by pesticides spreading and habitat decline. Milkweed plants which are the butterflies’ single sustenance source are decreasing in numbers with the use of herbicides for different crops.
