環境の豊かさ

環境汚染が少なく、自然が豊富で、環境が多様であれば蝶が多く生息しやすい。
つまり、蝶は環境の豊かさの指標となるという。
子供の頃はザリガニやホタルが地元にいたものだがめっきり見なくなった。
都市部において蝶を見ることも稀である。
都市部こそ緑化が必要だが、行政の条例等では経済優先で逆の基準となっている。

 

ENVIROMENTAL RICHNESS [ Mar 16 2010 by ST ]

 

If the environment is not much polluted where nature is full with variety of surroundings, there are many butterflies in such environment and it is easy for them to inhabit there.
In other words, it is said that butterfly could become an indicator of the richness of environment.
In my childhood, we could easily find crawfishes and fireflies in my local neighborhood, but nowadays they are seldom found. Also, it is quite rare to see butterflies in city area.
Greening project is necessary especially for cities but those regulations etc. of governmental administration put priority almost on economy, bringing about an adverse standard.
