Controlled burning in cooler months, to reduce fuel loads, was given up in many places after city people protested about smoke hazes.

此前的策略是在凉爽的季节里，有控制地燃烧部分森林，以减少可燃物载量（fuel loads），由于市区民众纷纷抗议由此引起的烟雾，这个办法已经在许多城市被弃用。

In contrast, charcoal, made by partially burning wood in a controlled process, is a fuel that creates less smoke than wood does.

相反，在一个有控制的过程中通过部分燃烧木材而制成的木炭却是一种不会像木材那样造成大量烟雾的燃料。
