Question

Accepted Answer

# Brief Explanations:
1. Sediment contamination can carry pollutants like heavy metals, pesticides, etc. These can be toxic to fish and aquatic organisms. Enhanced water clarity ($ \times $): Sediment makes water murky. Increased biodiversity ($ \times $): Contamination harms life. Reduction in water temperature ($ \times $): Not a common direct consequence.
2. Land management aims for long - term viability. Ignoring environmental concerns ($ \times $): Bad for ecosystem. Minimizing land use ($ \times $): Not practical always. Maximizing land development ($ \times $): Can be unsustainable.
3. Desertification turns land arid. Increase in wildlife populations ($ \times $): Less resources. No effect ($ \times $): Obvious impact. Promotes invasive species ($ \times $): Not the main impact. Reduces habitat and food ($ \checkmark $): Key effect.

# Answer:
1. Harm to fish and other aquatic organisms
2. Responsible and sustainable land utilization
3. It reduces habitat and food sources, leading to a decline in wildlife populations.
