I hope the authorities can look into the maintenance of hedges along our expressways.
Constant pruning is required, given the fast-growing nature of the plants.
This is not only labour-intensive, but the associated traffic jams also have a significant impact on the environment and economy.
Such maintenance work is also a safety hazard for the workers and road users.
If we cannot do away with the hedges, perhaps more research should be carried out to find ways to limit the growth rates of these plants, or to find alternative species.
The end result is fewer traffic jams, large savings in maintenance costs and a reduction in our reliance on foreign workers.
