The activities that release greenhouse gases into Earth's atmosphere are:
1. Raising livestock.
2. Catching fish.
The activities that release greenhouse gases into Earth's atmosphere are raising livestock and planting forests.
To determine the correct answers, you can look at the nature of each activity and consider how it might contribute to greenhouse gas emissions.
1. Raising livestock: This activity involves the breeding and maintenance of animals for food production, such as cows, sheep, and pigs. Livestock are known to produce methane, a potent greenhouse gas, through their digestive processes. Methane has a much higher global warming potential compared to carbon dioxide. Therefore, raising livestock contributes to greenhouse gas emissions.
2. Catching fish: This activity, by itself, does not release significant amounts of greenhouse gases into the atmosphere. However, the processing and transportation of fish can contribute to emissions. For example, refrigeration and transportation of fish products may require the use of fossil fuels, which release carbon dioxide when burnt.
3. Growing flowers: Growing flowers generally does not directly release greenhouse gases into the atmosphere. However, it is essential to consider other factors related to flower production, such as the use of fertilizers and energy-intensive cultivation practices. Fertilizer production and application can lead to the release of nitrogen oxide, a greenhouse gas. Additionally, if flowers are grown in heated greenhouses using fossil fuels, the process may contribute to carbon dioxide emissions.
4. Planting forests: Planting forests, on the other hand, has a beneficial effect on greenhouse gas levels. Forests act as carbon sinks, absorbing carbon dioxide through photosynthesis and storing it in trees and the surrounding ecosystem. While forests can also release some greenhouse gases, the net result is a decrease in atmospheric greenhouse gas levels when forests are well-preserved, maintained, and expanded.
In summary, raising livestock and, under certain circumstances, growing flowers can release greenhouse gases into the atmosphere. Planting forests, on the other hand, helps to mitigate greenhouse gas levels.
