Synthetic Materials and Societal Impacts

Synthetic materials depend on natural resources from Earth’s land, ocean, atmosphere, and biosphere, many of which are non-renewable over human lifetimes.
Natural resources are unevenly distributed due to factors like geography and climate; for example, Russia has a large timber supply, while iron ore (used for steel) varies by country.
Economic conditions and climate determine which synthetic materials are produced, often prioritizing basic needs over entertainment in certain regions.

Material development is driven by societal needs, wants, and values, such as the global demand for cell phones to aid communication.
Ethanol, a renewable fuel from plant materials, has dual impacts: - Individual: It is less expensive than petroleum-based gasoline. - Societal: Its use reduces petroleum dependency and creates fewer pollutants, decreasing smog and acid rain.

Increasing demand for synthetic materials leads to habitat destruction and biosphere changes.
Draining wetlands for corn production (to make ethanol) can result in species extinction and damaged ecosystems.
Harvested resources like palm oil from equatorial regions lead to reduced biodiversity when rainforests are cleared.
Changes to biomes affect their ability to clean water and recycle nutrients.

Chemical reactions for synthetic materials often create by-products, which can be useful or considered waste.
Ethanol Production Formula: $C_6H_{12}O_6 \rightarrow 2CH_3CH_2OH + 2CO_2$ .
Disposal of synthetic materials is a major environmental issue; in 2010, over $125\,million$ cell phones were thrown away, resulting in the loss of $10,000\,pounds$ of gold into landfills and incinerators.

Synthetic materials can be engineered to reduce human impact, such as fertilizers coated in synthetic polymers that control nutrient release and protect groundwater.
Research into bacteria has driven industries for bioremediation (cleaning toxic spills), bio-fuels, probiotic foods, and medicines like penicillin.
Development is ultimately limited by current scientific research and available natural resources.
