Question

why is the world's loss of biodiversty a source of concern?

A: Humans depend upon other organisms for food and oxygen
B:species extinctions have been rare throughout history
c:loss of biodiversty is not a concern because extinctions are common
D: both a and b

Answer 1

The correct answer is **A: Humans depend upon other organisms for food and oxygen.**

Loss of biodiversity is concerning because it threatens ecosystems that provide essential resources and services, such as food, clean water, and oxygen, which are critical for human survival. While extinctions have occurred throughout history, the current rate of species loss due to human activity is alarmingly high and poses significant risks to ecological balance and human well-being. Therefore, option B is not accurate in the context of why loss of biodiversity is a concern.

Option C is incorrect because it underestimates the serious impact of ongoing extinctions and the rapid rate at which they are occurring today. Ultimately, only option A correctly highlights the direct dependence of humans on biodiversity.
