TASK. On your blog tell us whether you think logging should be allowed in New Zealand. Be sure to provide at least two reasons to support your argument



I think yes and no that logging can be allowed in NewZealand because firstly it provides jobs for family's and secondly you can keep warm when you want to start a fire. another good thing about logging is it provides you with things like pencils,paper and houses. The thing is that bad about logging is it wrecks homes for animals and they will have to live some where else. Also logging can minimise the amount of oxygen.
