Step 3
Explain why the use of peat is harmful to the environment.
Answer
The extraction and burning of peat release carbon dioxide into the atmosphere, which contributes to global warming. Moreover, the destruction of peat bogs disrupts local ecosystems and can lead to habitat loss for various species.
Step 4
Suggest two ways that this type of farming can damage the environment.
Answer
- Intensive farming can lead to soil erosion as crops are harvested, which removes minerals from the soil.
- The use of large farm machinery may cause soil compaction, reducing soil quality and disrupting water infiltration.
Step 5
Explain how the widespread use of antibiotics in farming is a threat to human life.
Answer
The widespread use of antibiotics in farming can lead to the development of antibiotic-resistant bacteria. When these bacteria enter water sources through animal waste, they can spread to humans, making infections harder to treat. This can result in diseases that are no longer curable due to antibiotic resistance, affecting public health significantly.
