Insect problems arose with the intensification of agriculture-the devotion of immense acreage to a single crop.

农业生产高度集中，大量的土地被用来种某一种庄稼，昆虫问题也就至。

Grain acreage will be kept stable, per unit crop yield will be increased, and the quality of grains will be raised.

稳定粮食播种面积，提高单产和品质。

The U.S. burns twice as many acres as it did three decades ago and Forest Service scientists believe the acreage burn may double again by mid-century.

美国的土地烧毁面积是30前的2倍，林务局的科学家们相信，纪中期，烧毁面积还将增加1倍。

According to the Alaska Fire Science Consortium, more than two and half times as much acreage burned in the northernmost state between 2001 and 2020 in comparison to the 1990's.

根据阿拉斯加火灾科学联盟的信息，对比上纪90代，2001-2020美国最北州的燃烧面积是原来的2.5倍。

That's only a small share of the total acreage that could benefit, about half a million acres in all, so it will be vital to prioritize areas at greatest risk of fire or drought.

受益的也只是少部分林地，大约五十万英亩的规模。因此优先处理火灾或干旱威胁最大的区域非常重要。
