Problems from weeds, weed control, cost Montana nearly 200 million dollars a year. Montana has lost agricultural areas from salinization, problems of forest management, problems of forest fires. Second item on my checklist: climate change. Yes -- the climate in Montana is getting warmer and drier, but Montana agriculture depends especially on irrigation from the snow pack, and as the snow is melting -- for example, as the glaciers in Glacier National Park are disappearing -- that's bad news for Montana irrigation agriculture.
Masalah gulma, pengendalian gulma, memberatkan Montana hampir 200 juta dolar setahun. Kehilangan tanah pertanian karena salinisasi (naiknya kadar garam), masalah manajemen hutan, kebakaran hutan. Hal kedua di daftar saya: perubahan iklim. Ya -- iklim di Montana jadi makin hangat dan makin kering, tapi pertanian Montana bergantung pada irigasi dari puncak salju, dan sekarang salju itu meleleh, contohnya, ketika glasier di Taman Nasional Glacier menghilang, itu kabar buruk bagi pertanian teririgasi di Montana.
