The Monarch Butterfly is on the verge of extinction. Around 90% of their population has vanished within a period of 2 decades, that means around 1 billion Monarchs are missing. Reasons contributing to their depleting numbers range from the destruction of their milkweed habitat, to illegal logging, and some studies attribute it to the changes in the cycle of weather.
