When I saw this picture I said, what a beautiful elephant, I believe that animals are a fundamental part of our lives, without them the ecosystem would not be complete, the world needs them to move forward, many people overestimate the meaning they have for the planet, and also for us humans, because, who is not happy to have a pet?
Particularly I have a pet, which although at the moment is not with me (is in another country), made my days happier, nothing like coming to your house and receive you with a kind of hug hehe... I think the joy they feel when they see us is nothing compared to that.
That's why psychologically speaking, animals are good for us, as much as we are good for them. To take a journey with a friend of that level is to help the world be a better world.
They help us reduce our stress levels, calm our anxiety, or help reduce it, they give us joy, they give us company, we will never be alone if we have them. We also feel useful to see that we can do things for someone else, that we can take care of them, feed them, that they depend on us in some aspects makes many of us feel stronger, it's like we are their parents. To me that's great.
In addition to helping them, we help ourselves by improving our health, both physically and mentally, because I believe that these things go hand in hand. Besides, why not, our pet can get to exercise with us, go for a walk or jog with them can be very beneficial for both sides, besides keeping us in shape.
Adopting or buying a pet (it all depends on what you want), will make this world a better place. I know this is true since I have one and everything I have told you has been part of my experience with him.
