A small fire

I could see a neighbor making a small fire yesterday evening.
After pruning away, she was burning the trimmed trees.

Here in the country, we can do like that.
In the cities, burning the dead grasses or trees in the field would be beyond imagination.

It's also one of the rural sceneries.

But recently, the town officials tell us not to burn but to bring them where there is a big and high-powered incinerator, because burning them at home would produce 'dioxin' that woud do great harm to our health.

Is it really so ?
