Translation

Few insects have captured our imagination like the monarch butterfly.
オオカバマダラほど私たちの想像力をかき立てる昆虫はほとんどいません。
Their migration is one of the most iconic wildlife spectacles in North America, and it starts in Mexico in the spring when the monarchs that spend the winter there travel back north to lay their eggs.
彼らの渡りは北米で最も象徴的な野生生物の光景の一つであり、春にメキシコで越冬したオオカバマダラが産卵のために北へ戻ることから始まります。
Most migratory monarchs belong to the third and fourth generation.
渡りをするオオカバマダラのほとんどは第3世代と第4世代です。
This super generation will live up to nine months.
このスーパー世代は最大9ヶ月間生き延びます。
Now, our monarchs will continue their journey south, and they will have to face new threats.
さて、私たちのオオカバマダラは南への旅を続けますが、新たな脅威に直面することになります。
As many of you know, climate change has many faces: droughts, heatwaves, or even snowstorms, like the one you are seeing in this picture, have become the major challenge for the monarchs in the short term.
ご存知の通り、気候変動には多くの側面があります。干ばつ、熱波、あるいはこの写真に見られるような猛吹雪などが、短期的にはオオカバマダラにとっての大きな課題となっています。
Don't let this beautiful illusion of plenty fool you, because the monarchs are in serious trouble.
この美しい豊かな幻想に騙されてはいけません。なぜなら、オオカバマダラは深刻な危機に瀕しているからです。
But there's also good news: there's many people trying to protect them, because the science is very clear.
しかし、良いニュースもあります。科学が非常に明確であるため、彼らを守ろうとする多くの人々がいるのです。
All the monarchs need is their habitat back, and we can do that by planting milkweed and by planting native grasses with flowers.
オオカバマダラに必要なのは生息地を取り戻すことだけであり、私たちはトウワタや自生の草花を植えることでそれを実現できます。
That's why thousands of citizens along the migratory route are turning their backyards into habitat for the monarchs.
だからこそ、渡りのルート沿いに住む何千人もの市民が、自分の裏庭をオオカバマダラの生息地へと変えているのです。
I know for sure that if there is one iconic species in North America, this is the monarch.
北米において象徴的な種が一つあるとすれば、それは間違いなくオオカバマダラだと私は確信しています。
