Earth's Resources and Sustainability
Utilising Earth's Resources
Humans use the EARTH'S RESOURCES for many essential aspects of life. These are NATURAL RESOURCES that have been made WITHOUT any human input, and we use these for WARMTH, SHELTER, FOOD and TRANSPORT. Here are some examples:
- WARMTH:
- Natural Gas: Widely used for HEATING homes and WATER.
- Firewood: Traditional source of HEAT, particularly in rural areas.
- SHELTER:
- Stone: Used in the construction of durable and weather-resistant STRUCTURES.
- Clay: Utilised for making BRICKS and tiles for building homes.
- Sand: Used to make CONCRETE, which is important in modern construction.
- FOOD:
- Soil: The foundation for growing CROPS and supporting agriculture.
- Fish: A natural source of nutrition, sourced from oceans, rivers, and lakes.
- TRANSPORT:
- Crude Oil: Converted into fuels like petrol and diesel, crucial for powering vehicles.
- Iron Ore: Used to produce steel, an integral material for vehicle construction.
The Earth’s Natural resources are often IMPROVED by MAN-MADE processes such as AGRICULTURE and SYNTHETIC PROCESSES. Here are some examples:
AGRICULTURALLY IMPROVED PRODUCTS
FOOD:
- CROP production has been INCREASED by the introduction of FERTILISERS.
- WILD-CAUGHT FISH are supplemented by FARM-RAISED FISH.
TIMBER:
- Naturally grown FORESTS are supplemented by managed timber PLANTATIONS that provide a continuous supply of wood for construction and paper production.
CLOTHING:
- Natural WOOL or SILK is supplemented by agriculturally produced cotton and hemp fabrics.
FUELS:
- Traditional WOOD LOGS for burning are supplemented by agricultural products such as corn ethanol or BIOFUELS made from various plant materials.
- Biodiesel produced from agricultural crops like rapeseed and soybean oil can supplement or replace petroleum diesel.
SYNTHETICALLY IMPROVED PRODUCTS
- Cotton: A natural fibre often supplemented by synthetic fibres like POLYESTER in clothing.
- Rubber: Natural rubber can be supplemented or replaced by synthetic rubber, commonly used in tyres and industrial products.
- Leather: Natural leather can be replaced with synthetic leather in furniture, clothing, and accessories.
- Wood: Natural wood in construction can be supplemented with engineered wood products like plywood.
Finite and Renewable Resources
There are two main types of resources:
1. FINITE RESOURCES:
- These are resources that will EVENTUALLY RUN OUT. They come from the EARTH, OCEANS, and ATMOSPHERE and include fossil fuels, metal ores and minerals. Once used, they cannot be replaced instantly.
2. RENEWABLE RESOURCES:
- Unlike finite resources, renewable resources can replenish naturally over time. Examples include solar energy, wind energy, and wood from managed forests.
The Role of Chemistry
CHEMISTRY is vital in the process of CONVERTING NATURAL RESOURCES into useful products. It plays a central role in:
- IMPROVING AGRICULTURAL PROCESSES: Chemistry helps in the development of fertilisers and pesticides, which increase food production.
- CREATING SUSTAINABLE MATERIALS: Through Chemistry, we can develop materials that meet our needs while ensuring that future generations can also meet theirs.
Sustainable Development
SUSTAINABLE DEVELOPMENT is a developmental approach that considers the long-term impact on the environment. Its goal is to create products that fulfil our current needs without depleting resources or harming the environment for future generations.
