Water is precious

I saw the movie Flow on the internet and I thought it was really scary.

The film shows how companies just put any water they like into bottles and then sell it to the public with false advertising. How do we know what we're getting is pure water?

Sweet water of life

OUR planet has a continuous water cycle that keeps moisture circulating. It starts when the sun's rays heat the Earth, heating the water on the planet's surface to the point where it evaporates, turns into vapour or steam, and floats up into the atmosphere.

Thirsty for creative solutions

Water is the raw material of life. There is no substitute. It makes up 75 per cent of our body mass. But of all the water on the planet, more than 97 per cent is salt water, and less than 3 per cent is fresh. Of that 3 per cent, about 0.3 per cent is contained in lakes and rivers, with the polar ice caps, glaciers and permanent snow accounting for more than 69 per cent.

Picture of the day

Unlike Hong Kongers, Finnish people are used to freezing weather conditions. Just after the New Year, the manager of a climate station in northern Finland measured the temperature at minus 41.3 degrees Celsius. A week-long period of unseasonally low temperatures has caused problems with frozen plumbing around the country. Do you know why frozen pipes burst easily?

Sufficient water intake keeps the body working at its very best

The human body is made up of 60 to 70 per cent water. Can you imagine what you would look like if all that water dried up? Not a pretty sight. Your body would be an ugly useless bag of skin, bones and dried-up organs.

The human body cannot function properly if we do not pour enough water into it.

Talks seek safe water solutions

If wars have been fought for land and oil, who is to say the next war will not be fought over access to clean water? While it might sound extreme, the perception of water as a scarce resource that has to be carefully managed and protected through legislation is picking up steam.

Ask Mr Brain... all will be explained
