Industrial revolution and environmental issues

The Industrial Revolution was the change from hand production to machine and factory production that began in Britain around 1760 and spread to Europe and the USA in the 19th century. It used coal-powered steam engines and mechanised industries.

Major technological developments (initial Industrial Revolution, about 1760–1840)

1. Textile machines – flying shuttle (John Kay, 1733), spinning jenny (Hargreaves, 1764), water frame (Arkwright, 1769), spinning mule (Crompton, 1779), power loom (Cartwright, 1785); cotton gin (Whitney, 1793).
2. Steam engine – Newcomen engine (1712) pumped water from mines; James Watt's improved steam engine (1769) powered factories, mills and later transport.
3. Iron and steel – coke smelting (Abraham Darby, 1709), puddling process (Henry Cort, 1784); later the Bessemer process (1856) for cheap steel.
4. Coal mining – coal replaced wood and water as the main energy source.
5. Transport – canals, better roads (McAdam), steam locomotive (Stephenson's Rocket, 1829) and railways; steamships.
6. Machine tools – lathes and standard parts allowed mass production.
7. Communication – electric telegraph (1830s–40s).

How the Industrial Revolution led to major environmental issues

1. Air pollution – burning coal released smoke, soot and SO₂; cities like London and Manchester suffered heavy smog (later the Great Smog of London, 1952, killed about 4,000+ people).
2. Climate change – burning fossil fuels raised atmospheric CO₂ from about 280 ppm before 1750 to over 420 ppm today, causing global warming.
3. Water pollution – factories dumped dyes, chemicals and waste into rivers (Thames "Great Stink" of 1858); sewage from crowded towns spread cholera and typhoid.
4. Deforestation and land degradation – forests cut for timber, charcoal and farmland; mining scarred the land.
5. Resource depletion – rapid use of coal, iron ore and later oil.
6. Acid rain – SO₂ and NOₓ emissions damaged forests, lakes and buildings.
7. Urbanisation problems – slums, solid waste, poor sanitation and noise.
8. Loss of biodiversity – habitat destruction and pollution.

Coal + steam --> factories, railways --> more coal
      |                                    |
   smoke, CO2, SO2                    mining waste

 smog, acid rain,                 land and water
 global warming                   pollution

Thus the Industrial Revolution brought great economic growth but also began most of today's environmental problems, which later led to environmental laws, cleaner technologies and the idea of sustainable development.
