Final answer:
The author's purpose is to promote the recycling of aluminum cans due to its energy efficiency and environmental benefits. They advocate for community involvement in recycling efforts and highlight the significant role aluminum recycling plays in sustainability.
Step-by-step explanation:
The author's purpose in this text is ecological advocacy, emphasizing the importance of recycling aluminum cans instead of throwing them in the trash. By highlighting that aluminum is an infinitely recyclable material and that recycling it saves energy and reduces emissions, the author encourages actions that benefit the environment. The text also points out that garbage creation and control are significant issues and that aluminum recycling is one of the most effective ways to address this problem, as it requires significantly less energy compared to producing new aluminum, thereby limiting greenhouse gas emissions.
When discussing the benefits of recycling, it is important to note that while recycling is visible in society and has its advantages, it still requires energy to process recycled goods. However, recycling aluminum not only saves on energy but also reduces the need for expensive infrastructure such as landfills and mines. Moreover, recycling also plays a part in reducing the capital costs associated with the international shipping of raw materials.
In the context of community efforts, the author suggests that if recycling is not already a part of school programs, it provides an opportunity for individuals to take initiative and start a recycling club or organize better recycling goals. This fosters a collective effort to spare our environment from the long-term impacts, such as the centuries of decomposition that plastic waste contributes to in landfills.
