Introduction
There are many reasons to conserve biodiversity. These reasons can be grouped into three main categories, which are the following:-
● Narrowly utilitarian

Broadly utilitarian
Broadly utilitarian refers to the importance of biodiversity in providing ecosystem services. For example, Amazon rainforests provide 20% of the total oxygen in the atmosphere.
