Learn how kangaroo gut microbiomes could curb global warming, in this episode of Gross Science from NOVA. Greenhouse gases, like carbon dioxide and methane, are gases in our atmosphere that trap heat. In moderation, greenhouse gases are vital to life on Earth. However, when the levels of greenhouse gases in the atmosphere are too high, the planet warms dangerously. Cows release a lot of methane through their burps, farts, and manure. Kangaroos have a plant-based diet like cows but they release much less methane because they have different microbes in their guts. If researchers can figure out how to make cow guts more like kangaroo guts, they could help curb global warming. This resource is part of the NOVA: Gross Science Collection.
