The primary explanations for why livestock contribute to greenhouse gas emissions are:
1. **Methane escapes from the bodies and manure of livestock, due to their digestive systems.** - This is accurate because ruminant animals like cows have a digestive process that produces methane, a potent greenhouse gas.
2. **The number of animals in each herd produces large amounts of carbon dioxide, through respiration.** - This is also true; all animals produce carbon dioxide as part of their metabolic processes.
The other options regarding transport and land use are less directly related to greenhouse gas emissions as a primary cause. While transportation can contribute to emissions, it is not a direct function of livestock themselves. Similarly, while land use for livestock can impact carbon sequestration, the extent to which livestock reduce land for photosynthesis varies and is a more complex issue.
In summary, the first two options are the primary explanations for livestock's contribution to greenhouse gas emissions.
