Question
Select the correct answer from the list.(2 points)
A state is looking to adopt new management protocols for a metal resource within its borders. Two proposals are being considered. Determine whether each proposal will have a positive or negative impact on the environment and sustainability of the metal resource.

Proposal 1: Offer free recycling services for the metal.
Proposal 2: Burn waste and recover the metal from the ash.
Proposal 1 will have a

impact on the sustainability of the metal resource.

Proposal 2 will have a

impact on the environment. It will have a
Select Answer
impact on the sustainability of the metal resource.

Proposal 1 will have a positive impact on the environment. It will have a positive impact on the sustainability of the metal resource.

Proposal 2 will have a negative impact on the environment. It will have a negative impact on the sustainability of the metal resource.

Proposal 1: Offer free recycling services for the metal.

This proposal will have a positive impact on the environment. Recycling metal reduces the need for mining and extraction, which can be damaging to the environment. By offering free recycling services, the state encourages the proper disposal and reuse of metals, minimizing environmental impact.

It will also have a positive impact on the sustainability of the metal resource. By promoting recycling, the state aims to extend the lifespan of the metal resource by reusing and repurposing it. This reduces the reliance on virgin metals and preserves the availability of the resource for future generations.

Proposal 2: Burn waste and recover the metal from the ash.

This proposal will have a negative impact on the environment. Burning waste releases pollutants and can contribute to air pollution and climate change. It also poses risks to human health. Additionally, the process of recovering metal from the ash may involve the use of harmful chemicals, which can further harm the environment.

It will have a negative impact on the sustainability of the metal resource. Burning waste to recover metal is not a sustainable practice as it relies on the consumption of additional resources, such as fuel and energy. It does not contribute to the conservation or responsible management of the metal resource.

To determine the impact of each proposal on the environment and sustainability of the metal resource, let's analyze them one by one:

Proposal 1: Offer free recycling services for the metal.
To evaluate the impact on the environment, we need to consider the process of recycling. Recycling metal generally requires less energy and fewer resources compared to extracting and refining new metal from raw materials. Therefore, offering free recycling services for the metal would have a positive impact on the environment because it promotes the reuse of existing metal resources and reduces the need for new mining and extraction.

To evaluate the impact on the sustainability of the metal resource, we need to consider the long-term availability and viability of the metal. By implementing free recycling services, the state encourages the collection and recovery of metal, extending its lifespan and reducing the reliance on new extraction. This promotes the sustainability of the metal resource.

Therefore, for Proposal 1:
- Impact on the environment: Positive
- Impact on the sustainability of the metal resource: Positive

Now let's move on to Proposal 2: Burn waste and recover the metal from the ash.
To evaluate the impact on the environment, burning waste can release pollutants and contribute to air pollution. This process may also generate other harmful byproducts, depending on the composition of the waste being burned. Therefore, burning waste to recover the metal from the ash would have a negative impact on the environment due to the potential pollution and emissions associated with the burning process.

To evaluate the impact on the sustainability of the metal resource, the burning process doesn't directly affect the availability of the metal resource. However, it may not be the most efficient method for recovering metal, and the efficiency of metal recovery from ash may vary depending on factors like waste composition and technology used. This could potentially affect the overall sustainability of the metal resource if the recovery process is not optimized.

Therefore, for Proposal 2:
- Impact on the environment: Negative
- Impact on the sustainability of the metal resource: Potentially negative

In summary:
- Proposal 1 has a positive impact on the environment and the sustainability of the metal resource.
- Proposal 2 has a negative impact on the environment and may have a potentially negative impact on the sustainability of the metal resource.
