Sample Answer for Sustainable urban living [6 marks]

The greenhouse development relies on renewable energy, meaning fossil fuels are not being consumed. Since fossil fuels are in limited supply and will eventually run out, using renewable sources like solar and wind energy helps make the Earth more sustainable and self-sufficient. Cycle lanes and car-sharing schemes also promote more sustainable living by reducing the number of cars on the road. This lowers CO2 emissions from car engines, thereby decreasing air pollution. It also reduces the consumption of petrol and diesel, conserving fossil fuels. Cycling additionally provides health benefits. Furthermore, the allotments, where residents grow their own vegetables, reduce reliance on supermarkets for food. This encourages self-sufficiency among tenants and supports sustainable eating practices.
