萤火虫正在美国东北部的夏日天空升起, 在后院和城市公园创造了壮观的表演。 Fireflies are lighting up the summer skies in the U.S. Northeast, creating spectacular shows in backyards and city parks. 尽管能见度有所提高,但专家们警告说,由于生境丧失、农药使用和轻污染,萤火虫人口仍在迅速减少。 Despite the increased visibility, experts warn that firefly populations are still declining rapidly due to habitat loss, pesticide use, and light pollution. 过量的城市灯光使得萤火虫很难找到伴侣。 Excessive city lights make it hard for fireflies to find mates. 为了帮助保护他们,建议在夜间关上户外灯,避免杀虫剂。 To help protect them, turning off outdoor lights at night and avoiding insecticides are recommended.
