Study Notes

The Carbon Cycle and Human Prosperity

Understanding and manipulation of carbon and nitrogen cycles have propelled human prosperity.
Discovery and extraction of hydrocarbons sparked the Industrial Revolution, enabling unprecedented economic growth.
Carbon is fundamental to life, forming strong bonds and diverse molecules, essential for energy transfer.

Properties and Importance of Carbon

Carbon can form both robust materials (diamonds) and weak materials (graphite).
Acts as a key component in power generation, food supply, and overall economic structure.
Carbon transitions through the food chain, promoting life and supporting apex predators.

Role of Carbon Dioxide

Carbon dioxide (CO2) is vital for life; plants absorb CO2 and release oxygen (O2) through photosynthesis.
Photosynthesis is the process where plants convert sunlight, water (H2O), and carbon dioxide (CO2) into stored energy and sugars.
Carbon atoms circulate through the food chain, enhancing the survival and prosperity of various species.

Carboniferous Period and Fossil Fuels

The Carboniferous Period began around 400 million years ago when some carbon molecules evaded consumption.
Carbon was buried in swamps and ocean beds, avoiding oxygen exposure and predation, leading to fossil fuel formation.
The natural refinement of carbon under Earth's pressure and temperature resulted in the creation of coal, oil, and natural gas.

Impact of Fossil Fuels on Society

Fossil fuels represent concentrated hydrocarbons, acting as energy storage derived from centuries of photosynthesis.
Exploitation of these energy resources has significantly influenced societal advancement over the last two centuries.
The availability of fossil fuels created a new energy surplus equation, drastically transforming human civilization.
