Question

for the new study, scientists looked at more than 12 million butterfly sightings across the u.s. (hawaii and alaska weren’t included.) they were taken from 35 different butterfly counting programs from 2000 to 2020. some sightings were from people just writing down the butterflies they saw during a park visit. other butterfly counts were much longer, like those run by jeffrey glassberg in westchester county in new york. glassberg is the founder of the north american butterfly association. his organization’s butterfly counts use bigger teams of people. they carefully survey landscapes 15 miles in diameter for every fluttering insect they can see. glassberg has been surveying the area for more than forty years. in that time, he’s seen about 10 butterfly species vanish. (a species is a group of similar living things. members of a species can reproduce successfully to make offspring.) among the lost is the ghostly white butterfly called the acadian hairstreak. it kills glassberg to see butterflies vanishing. but his organization’s butterfly counts, he said, are important for building the next generation of butterfly lovers.

Explanation:

The text is about scientists studying butterfly sightings, species disappearance, and conservation efforts, which relates to the study of living organisms and their environments, falling under Biology (a subfield of Natural Science).
