🌼 Bugs and ecosystems

Pollination happens when a bug carries tiny grains of pollen from one flower to another, which allows plants to make seeds and grow the fruits and vegetables we eat. Flowers attract bugs with bright colours, sweet scents and nectar, a sugary treat, and pollen sticks to the bug's body almost by accident as it feeds. Without pollinators visiting flower after flower, many plants would never be able to reproduce at all.

Bees pollinate an enormous share of the fruits, vegetables and nuts that end up on our plates, from apples and almonds to pumpkins and berries. Without enough bees visiting crops, farmers would harvest far less food, and some fruits would barely grow at all. Bees also pollinate countless wild plants, which in turn feed and shelter many other animals across the whole ecosystem.

Certain bugs act like nature's cleanup crew, beetles and flies break down fallen leaves, dead wood and even animal droppings, turning them into nutrients that soil can reuse. Without these tireless recyclers, forests and fields would slowly pile up with waste that never breaks down. Some bugs specialise in a very specific job, like burying dung underground almost as soon as they find it.

If insects vanished overnight, most flowering plants would stop being pollinated and slowly disappear, taking away food and shelter for countless birds, mammals and other animals. Fallen leaves and dead wood would pile up uncleared, since so many insects normally break that material down. Scientists generally agree that losing insects would collapse whole food chains, since so many other species depend on them directly or indirectly.
