1. Noise levels in workplaces (especially cafes, restaurants) will be increasingly recognized as contributing to stress and later-life hearing loss for people who work in those environments. What is considered a "safe" noise level will decrease drastically. 2. People will become more concerned about air pollution than climate change; emissions from combustion engines, brakes, and tires will be increasingly in the public eye. Office workers will become concerned about CO2 levels in their workplaces, and on their commutes. Many workplaces will install equipment to provide fresher, cleaner air. 3. Ebikes, electic scooters, and other relatively compact electric transportation quietly revolutionise commuting for people who live within 20-30km of their work. 4. Work weeks (or at least time in office) will decrease for many office workers. It will become normal for many people to only go into the office once or twice a week. 5. The combination of 1, 2, 3 and 4 above lead to increasing de-urbanization as people who can afford it seek to move to quieter places with cleaner air. Clean air becomes a major issue of inequality. Productive farmland around cities is converted to large home-office plots with lots of trees. 6. At least one climate change mitigation geoengineering idea will have a large scale proof of concept experiment conducted 7. Microplastics in the food supply / ecosystem will turn out to be not that serious of a health problem for people and most other animals (some animals will be severely affected)
