'Canary in a coal mine'... exactly. The number of species that have gone extinct or are now endangered is astounding. The sad reality is that many of these species are in danger because of our actions- pollution, food hunting, urban sprawl, habitat loss, climate change, ecosystem disturbance. The future looks grim for many creatures because of our daily endeavours, and the future/past of species helps to tell us the health of the Earth. Sure a little lightning bug poses little risk to the well being of mankind, but the chain effect of one specie or the repetition of hundreds of dying species does suggest a critical problem.
