Answer:
They have joined together to work towards better land management practices.
Step-by-step explanation:
The statement "They have joined together to work towards better land management practices" provides evidence that steps are being taken to help minimize harm to the Great Barrier Reef. The fact that the Queensland Farmers' Federation, an organization of 2,600 farmers who have land along the Great Barrier Reef, have joined together to work towards better land management practices suggests that they recognize the importance of their actions in protecting the reef. By working together, these farmers are taking a proactive approach to improving their land management practices, which can help to reduce the negative impact of farming on the Great Barrier Reef. This evidence supports the idea that farming practices can help to minimize harm to the reef.
