Answer:
We need to prevent accidental wildfires, and some we need to start on purpose to fertilize the soil.
Step-by-step explanation:
Accidental wildfires pop up out of nowhere. Maybe a bolt of lightning lit a tree on fire, or sparks from wires set a forest on fire. Either way, they come and go without warning, which makes them extremely dangerous for people, the animals native to that area, and even the environment. Firefighters have a hard time getting them under control, which is why they must be prevented.
Sometimes though, when soil isn't fertile enough, we set enormous amounts of land ablaze on purpose to revitalize the soil with nutrients and minerals. It is important to do this so that plants can grow back healthier then before and make the soil last longer, and prevent erosion.
