OK so I am a bit late to participate in this contest but I will still do something.
I will start by saying that when the word gratitude is mentioned any where in the world that means gratefulness, appreciation, thankfulness. It means you appreciate what is given to you or what you have seen etc. It has a whole lot of meaning. So according to this contest one could rightly say that the Hallmark of this topic is to show how grateful you are to nature. How appreciative you are to the green grass, vegetations, aquatic, terrestrial and arboreal animals and a whole lot.

Now nature is one thing I don't joke with, ranging from the animals, to the vegetations, green grass, fishes in the water, birds in the air, flowers in our surroundings etc.
I am a lover of nature and anyone close to me will see that I mostly take pictures of flowers, the sky, water, animals etc.
I enjoy watching this things so much. Have you ever imagined taking a stroll wish your lover ana the evening breeze caress round your face, the trees dance up and down as Is if the support your union, or perhaps calling Gods attention to see the two love birds.

If you have ever loved and you go our with your loved ones whether husband, wife, children, siblings etc to a field or open space full of flowers ana green grass how do you feel?
You will feel this serenity, calmness, love and all good feelings one could ever imagine or think of.
Staying close to Nature has a way of bringing peace to a trouble mind.
Ever felt worried and just going to sir close to the waters your mind just automatically wonders away from the thoughts that clouded your mind?

God knew why he created all this things, He knew it would be of great use to us humans.
Below are pictures of few flowers are took, they were too beautiful so I couldn't afford to just pass it by. I might probably not know their names but I plead that you enjoy watching them.
