Module 5, Lecture 4 (Climate Change on the Farm)

A set of flashcards summarizing key concepts discussed in the ANBI 110 lecture on climate change and its effects on domestic animal production.

What are the key points discussed about climate change in this lecture?

1. It is warming. 2. It is us. 3. We are sure. 4. It is bad. 5. We can fix it.

What impact does livestock have on climate change?

Livestock contributes to greenhouse gas emissions through enteric fermentation, manure management, and land use change.

What are the primary sources of methane (CH₄) emissions?

Agricultural activities, waste management, energy use, and biomass burning.

What are some strategies to mitigate greenhouse gas emissions from livestock?

Strategies include improving forage quality, feeding practices, manure management, and animal genetics.

How does climate change affect livestock reproduction?

Climate change decreases the reproduction efficiency in cows, pigs, and poultry, affecting overall production rates.

What are the positive effects of increased CO₂ on plants?

Partial stomata closure, reduced transpiration, and improved water-use efficiency of pastures.

Why is there uncertainty regarding the impacts of climate change on livestock?

The benefits and negative impacts are complex and not fully understood, particularly regarding water availability for livestock.

What is the projected climate change outcome for livestock production?

Climate change is already present and expected to worsen, leading to various impacts on livestock production systems.

How does land use change due to livestock contribute to climate change?

Land degradation from livestock operations, such as deforestation and soil degradation, increases greenhouse gas emissions.

What role do genetic capabilities play in livestock adaptation to climate change?

Identifying breeds with inherent genetic capabilities to adapt is important for livestock sustainability in a changing climate.
