Weeds are harmful in agriculture because they rob nutrients from the crops. They also use space that could be used for crops, they block air circulation that crops need to grow, they block sunlight, and they use water that should be going to the crops.

Why are weedplants important for the environment?
"Weeds" are important for a multitude of reasons (far too many to list). However, here are just a few. 1. They provide food for many animals. Deer, rabbits, caterpillars, and other creatures eat their leaves, birds may eat their seeds, and bees and butterflies rely on the nectar from their flowers. 2. They provide shelter for small animals. Birds, rabbits, mice, and other small animals may use their twigs to build nests. Other animals may hide among them to avoid being seen by predators or prey, or to stay cool on a hot day. 3. Weeds hold the soil in place, and prevent erosion. 4. After a forest fire, volcano, or other natural disaster destroys a habitat, weeds are the first plants to grow their, because they are very hardy. This prevents erosion, and, eventually, allows other plants to grow there again.
