The critical decline of grasslands:

Grasslands rank among the most imperiled and least protected biomes on Earth. They are disappearing even faster than forests, and much of what remains has suffered varying degrees of damage. Their decline threatens a huge chunk of the planet’s biodiversity, the livelihoods of roughly 1 billion people, and countless ecological services such as carbon and water storage. Yet these losses don’t register with the same force as deforestation. Perhaps because we do not notice, or perhaps because we do not care.
