The key answer of exercise 4

Yes, Vancouver is indeed green. They've been committed to the Greenest City Action Plan since the early 2000s. This initiative aims to reduce emissions, conserve water, minimize waste, and increase green spaces. Their efforts have paid off with lower emissions, reduced water usage, increased sustainable transportation, and improved air quality. They manage waste through composting and promote community gardens, cycling infrastructure, and carpooling incentives. As a result, Vancouver has visibly become greener over the years.
