Covering our reservoirs with solar panels would be an ecological mistake (Floating solar farms at reservoirs a powerful idea, by Mr Paul Chan Poh Hoi; Oct 16).

Most people see only the calm surface of our reservoirs but, in fact, there is a complex ecological environment underneath.

Aquatic plants not only provide the water with oxygen, but they also help absorb excess nutrients and neutralise toxins produced by fish.

When we cover the water surface, we will be depriving the aquatic plants of sunlight, thus disrupting the established balance.

The result would be a catastrophe for nature as well as for the quality of our water supply.
