Air pollution is Hong Kong's biggest problem, and it is the city's young people who will suffer most. So says a leading environmentalist who was in town over the Easter holiday.
If the air quality does not improve soon, today's teens will face serious health problems in their 30s and 40s, warned Alan Watson Featherstone, a Scottish conservationist.
But although young people will be the ultimate victims, they are also the solution.
'Young people should put pressure on policy makers, and force the government to bring in tighter pollution control regulations,' he said.
'The air in Hong Kong is among the most polluted in the world. People wear face masks and this is not natural.
'The city is rich and has plenty of money, but the government has not put much effort to tackle the problem. There is no excuse not to do it.' Featherstone said.
