Question

1)Учёные полагают, что если не предпринять срочных мер по нормализации экологической обстановки, то на Земле в результате деятельности человека к 2030 году исчезнет 20000 видов особей в год. Сколько видов будет исчезать каждый час?

Answer 1

в год - 20000

в месяц - 20000 : 12 ≈ 1666,6

в день - 1666,6 : 30 ≈ 55,5

в час - 55,5 : 12 = 4,625

Answer 2

To calculate how many species will disappear every hour, we need to convert the annual rate of species extinction into an hourly rate.

Given that 20,000 species will disappear annually by 2030 due to human activities, we can calculate the hourly rate as follows:

Number of species disappearing each hour = (Total number of species disappearing annually) / (Number of hours in a year)

Let's calculate it:

Total number of species disappearing annually = 20,000 Number of hours in a year = 365 days * 24 hours/day = 8,760 hours

Number of species disappearing each hour = 20,000 / 8,760 ≈ 2.283

So, approximately 2.283 species will disappear every hour if urgent measures are not taken to normalize the ecological situation by 2030.
