Which of the following is not a renewable resource?

Correct option is B

The correct answer is option (b) Iron ore.

Explanation

Iron ore is a non-renewable resource because it is a finite material that cannot be replenished on a human timescale. Once extracted and used, it cannot be regenerated naturally within a short period. Non-renewable resources like iron ore are typically mined and used for industrial purposes, such as steel production. These resources are being depleted faster than they can naturally form, making their availability limited.

In contrast, renewable resources are those that can be naturally replenished over time. For example, solar energy, wildlife, and forests are all renewable resources:

• Solar energy: The energy from the sun is renewable because it is constantly available and can be harnessed indefinitely without depletion.

• Wildlife: Wildlife populations can regenerate and replenish as long as ecosystems remain intact and sustainable practices are in place to protect them.

• Forests: Forests can regenerate through natural growth or through human intervention (such as reforestation). However, this regeneration depends on responsible management to avoid deforestation.

Information Booster

• Iron ore is classified as a mineral resource and is essential for the production of steel but is finite and cannot be regenerated.

• Solar energy is a major source of clean energy and does not deplete, making it central to sustainable energy strategies.

• Wildlife conservation relies on maintaining healthy ecosystems where species can reproduce and maintain their populations.

• Forests play a critical role in regulating climate, providing oxygen, and serving as habitats for biodiversity, and their regeneration requires time and careful management.

• Sustainable practices in the use of renewable resources help ensure their continued availability.

Additional Knowledge

Expanding on the other options:

1. Solar energy: Solar power harnesses energy from the sun using photovoltaic cells or solar thermal systems. It is considered one of the cleanest and most abundant renewable resources because sunlight is freely available every day. Solar power is critical to reducing reliance on fossil fuels and combating climate change.

2. Wildlife: Wildlife includes all animals, birds, fish, and insects found in natural ecosystems. While wildlife is renewable, its regeneration is contingent on the preservation of natural habitats and sustainable hunting and fishing practices. Over-exploitation, habitat loss, and climate change are significant threats to wildlife populations.

3. Forest: Forests are essential for the planet's ecological balance, providing oxygen, sequestering carbon dioxide, and supporting biodiversity. Although forests are renewable, overharvesting, deforestation, and climate change can hinder their regeneration. Therefore, sustainable forest management practices are necessary to ensure their long-term health and productivity.
