An interesting article about what it's like to live on a canal boat in London at Euronews. Here's a snippet:
A study on the environmental impact of household consumption in 2015 highlighted that over 60% of global greenhouse gas emissions derive from houses on land. As one of the main criteria considered was size, many were prompted to join the ‘tiny house’ movement to improve their ecological footprints. Much like canal boats, ‘tiny houses’ (typically measuring under 400 square feet) require less energy to heat and are therefore more sustainable. Among 80 ‘tiny home’ downsizers studied in the United States, environmental impact was thought to be 45% less. The factors they considered included reduced building material waste, and a propensity to grow and make food more locally as the houses tended to be in more rural areas.
