Just an observation:
only in the past a couple of decades or so do we start to understand the extreme importance of roles that frogs play in the ecosystem and ecology.
Here's few reasons why:
Frogs are an integral part of the food web
Tadpoles keep waterways clean by feeding on algae. Adult frogs eat large quantities of insects, including disease vectors that can transmit fatal illnesses to humans (i.e. mosquitoes/malaria). Frogs also serve as an important food source to a diverse array of predators, including dragonflies, fish, snakes, birds, beetles, centipedes and even monkeys. Thus, the disappearance of frog populations disturbs an intricate food web, and results in negative impacts that cascade through the ecosystem.
Frogs are bioindicators
Most frogs require suitable habitat in both the terrestrial and aquatic environments, and have permeable skin that can easily absorb toxic chemicals. These traits make frogs especially susceptible to environmental disturbances, and thus frogs are considered accurate indicators of environmental stress: the health of frogs is thought to be indicative of the health of the biosphere as a whole. Frogs have survived in more or less their current form for 250 million years, having survived countless ice ages, asteroid crashes, and other environmental disturbances, yet now one-third of amphibian species are on the verge of extinction. This should serve as an alarm call to humans that something is drastically wrong in the environment.
Humans use frogs in medicinal research
Frogs produce a wide array of skin secretions, many of which have significant potential to improve human health through their use as pharmaceuticals. Approximately 10% of Nobel Prizes in Physiology and Medicine have resulted from investigations that used frogs. When a frog species disappears, so does any promise it holds for improving human medicine.
But 1,400 years ago prophet Muhammad SAW already warned us not to kill or endanger frogs!
I bet no one knew the reason and not until in the past decade or so with the drastic climate change do we understand why frogs are so important.
This is yet another latest evidence of how the truth of Islam is revealed one by one.
