A hummingbird can beat its wings at 50 beats per second, which is so fast that it looks like a buzzing blur in the air. Hummingbirds are also able to zoom up to a flower at 40 kilometres per hour (24 miles per hour) and stop in an instant.
Young salmon escape fish farm's net pen
Young salmon escape fish farm's net pen The first major escape of fish into British
Columbia's waterways occurred this year, with 30,000 farmed female
chinook salmon getting away. The salmon were kept in a net pen in
Kyuquot Sound where a boat propellor tore the net, allowing the
escape. This raises again the issue of net pens. Many
environmentalists believe that they are not strong enough and are
concerned that escaped farmed salmon will breed with native species
and alter the gene pool. 5 MAY 2000
