On the open day at my son's school ,I also visited the high school.
But some of the students hung down their heads and looked lethargic,so I lost interest in the math class.
In my son's second class his teacher discussed the subject of biodiversity,although it was supposed to be "moral education".
He asked everybody including parents if the number of species had increased or decreased.
I was embarrassed as I didn't know the right answer.
After he had given us the correct answer that the number of species are fewer compared to ages ago, he asked us again if the fact is good or not for people.

My son raised his hand and responded to him.
If certain plants become extinct,others which depend on them also will die in the future ,when the ecosystem collapses humans will have a hard time surviving.
