Bugs are very common. Although you may think they're annoying, If you look closer you may be able to see their beauty, even when they seem strange. Mushrooms also play a major role in our ecosystems, decomposing dead organic matter like no other organism, along with some artificial toxins. Lichens, fungi housing photosynthetic symbionts, take the first step of turning barren islands into thriving ecosystems, and turn sunlight into energy in places nothing else can.
