Dogs
Dog owners normally have a stronger immune system, helping them to stay well and spend less time getting over sicknesses and diseases. Nothing beats a long walk with your four-legged friend on a fresh, spring morning. Or seeing the joy on their faces when you pick up a ball and they know it’s playtime in the local park! Even relaxing at home feels better in each other’s company.One of the unexpected benefits of dogs is the way they add to your social life. Going to obedience classes, saying ‘hello’ to other dog walkers when you go to the park with your canine companion – there are dozens of ways in which your dog makes you more sociable.
Your new puppy will get you out and about, trying things you never considered before and introducing you to new experiences. Whether you’re going to a new pet shop or exploring a new area to make your dog’s daily walk more interesting, you’re bound to see new people all the time. You’re unlikely to stop for a chat with a stranger when you’re walking by yourself, but we all know how easy it is to talk when our dogs want to make friends. And, no matter how different we are, we have something in common – our highly sociable, friendly dogs!One of the most fascinating benefits of dogs is their amazing ability to make us feel calm - and that has a brilliant effect on our health.

Naturalist and Environmentalist, John Muir had a very romantic almost religious view of the nature. To Muir, the trees were divine and Americans had a moral and ethical duty to save them. He defined the redwoods as Christ-figures being crucified by men: <em>"Any fool can destroy trees. They cannot defend themselves or run away. And few destroyers of trees ever plant any; nor can planting avail much toward restoring our grand aboriginal giants. It took more than three thousand years to make some of the oldest of the Sequoias, trees that are still standing in perfect strength and beauty, waving and singing in the mighty forests of the Sierra. Through all the eventful centuries since Christ's time, and long before that, God has cared for these trees, saved them from drought, disease, avalanches, and a thousand storms; but he cannot save them from sawmills and fools; this is left to the American people." </em> He makes a connection between the reader and trees by personifying the trees and making them able to feel both joy and pain,<em>"Waving its branches for joy". </em>He also argues: <em>“Any fool can destroy trees. They cannot run away; and if they could, they would still be destroyed.” </em>
The crowd, because it identifies a group of people and still sounds like a singular noun.
