Final answer:
The sun is a perpetual resource due to its continuous and expected solar radiation for the next 6 billion years. Natural capital degradation mainly results from unsustainable practices. Recycling is less preferable compared to reducing and reusing because it still requires energy and can pollute.
Step-by-step explanation:
The type of resource that the sun represents is a perpetual resource because solar radiation continuously streams from the sun without interruption and is expected to do so for approximately the next 6 billion years, according to scientific understanding. Therefore, the correct answer to the first question is A: The sun is a perpetual resource because solar radiation steadily streams from the sun without interruption and is expected to do so for the next 6 billion years.
Natural capital degradation is often the result of C. unsustainable practices. These practices can deplete resources faster than they can be renewed and cause long-term harm to the environment.
When it comes to environmental solutions, recycling is not as good as reducing and reusing because recycling still consumes energy, often from fossil fuels, and can result in pollution. The correct answer to the third question is A: Recycling still uses energy (fossil fuels) and puts pollution in the air.
