Importance of insects 昆蟲的重要性

By the end of this lesson, you will be able to identify stress-related problems and offer solutions.

ADVENTURER: When you think of endangered species, which animals do you think of? The tiger? The elephant? The panda? Ah, I get it.

ADVENTURER1: You like the rock stars of the animal world, the famous, good looking ones, hey? The ... celebrities. Me too. I mean, which animals do you prefer: the lion ... ... or the ... beetle? It's just not easy to like ugly animals, is it?

ADVENTURER2: Especially ... insects. Insects! They're everywhere! You know, there are more than a million known species of insect, and maybe as many as thirty million species that we don't even know about yet! Whoa!
ADVENTURER3: That's a lot of bugs! But what good do insects do for us? Well ... you like honey, don't you? What about that nice silk shirt? Both made by bugs ... and, can you imagine, if there were no spiders, how many flies there'd be?

ADVENTURER4: We need insects to eat other insects! And in fact, some insects are delicious! Full of protein. Oh, and perhaps the most valuable thing insects do for us: pollination. Insects help make it possible for flowers and grasses to reproduce.

ADVENTURER5: We all agree that flowers are beautiful, right? Well, if there were no insects, there would be a lot less flowers. Furthermore, all the animals at the top of the food chain depend on animals and insects at the bottom of the food chain. Think about it. If there were no insects, there might be no lions, no tigers, no elephants, no ... humans.
