How Do Animals Not Help Plants?

Well, most plants and animals, in nature work together.  Plants provide food, and animals help spread their seeds.  The only time an animal is a problem is if your dog tears up your flower bed to bury a bone.  They can't help it. It's the way they are made.  Otherwise, I can't see how animals have a negative effect.  Even some insects who attack plants, down the line, it helps the plants to replenish themselves.  Every 7 years or so, we get an epidemic of these little green bugs, but they only attack a certain type.  Time to cut your hedges, which overall helps in their growth in time.  There are some foreing bugs and animals that may not me native to your region and are accidentally brought over.  Then that can be a problem - such as in Australia, where rabbits were introduced, and now they are worse than mice from eating everything in site.  As well as sheep.  They eat grass down to the root, so unless in constant motion, moving from place to place, they can destroy large areas of land
