Question

one reason for the conservation of wildlife

Answer 1

Hey!

As you asked for just one reason so wildlife must be conserved as their extinction might lead to a disturbance in food chain.

In food chain every member has a role to play, even if one of the member disappears it might cause a complete chaos in the system.

So wildlife must be conserved.

Hope it helps ^_^
