Is This Because

Long ago, in youth long gone, I spent hours at a pond, A clay base, sun adorning, Tadpoles swimming, half forming, I spied with a magnifying glass, Frogs finally hopped at last, Now, no frogs, cause no rain, Is it because of climate change? That was our ecological health, How can we restore our planet's wealth? So I ponder on such ponds, Where have all the tadpoles gone?
