Abstract: A device is provided for handling animal waste gas and suppressing global warming. The device includes a hood, a feces tube that is provided with a first one-way valve, and at least one waste gas tube that is provided with a second one-way valve. The waste gas tube has an end connected to a container. When an animal expels waste gas and fecal matter, the fecal matter is allowed to drop into the feces tube and passes through the first one-way valve. The waste gas is conducted through the second one-way valve into the container for storage. As such, the waste gases expelled from cows and horses can be re-used in order to reduce pollution caused thereby, increase energy sources, and suppress the greenhouse effect of the Earth.
