The monarch existence cycle starts off every one spring while it deposits eggs on milkweed leaves. yet this dependency of monarchs on milkweeds as nutrients isn't reciprocated, and milkweeds do all they could to poison or thwart the younger monarchs. Agrawal delves into significant medical discoveries, together with his personal pioneering study, and strains how plant poisons haven't purely formed monarch-milkweed interactions yet have additionally been culturally very important for hundreds of years. Agrawal provides present rules concerning the contemporary decline in monarch populations, together with habitat destruction, elevated iciness storms, and absence of milkweed—the final one a concept that the writer rejects.
