In GCSE Chemistry, you will learn about how we obtain and use Earth's resources, as well as ways to reduce our consumption and environmental impact. This topic covers key areas:
Access to clean drinking water is essential for life. You will study methods like desalination of seawater and purification of water from other sources to make it safe for human consumption.
Life cycle assessments evaluate the environmental impact of a product from raw material extraction to disposal. Recycling helps reduce waste and conserve resources. You will learn about recycling materials like metals, glass, plastics, and paper.
Strategies to reduce resource use include reusing products, repairing items instead of replacing them, and reducing unnecessary consumption and wastage. You will explore ways to apply these principles.
The Haber process is an important industrial method for producing ammonia from nitrogen and hydrogen gases. Ammonia has many uses, including fertilizer production. You will study the conditions and principles behind this process.
Consider the life cycle of a plastic water bottle:
A full life cycle assessment would quantify the environmental impacts at each stage, such as greenhouse gas emissions, water use, and waste generation. This data can guide efforts to reduce the product's environmental footprint through improved processes, recycling, or alternative materials.
By understanding how we source and utilize resources, as well as methods like recycling and sustainable practices, you can make informed choices to protect the environment and conserve Earth's limited resources.
