My dear brother
God created the creatures
We learned through the Holy Qur'an and the Hadith
1_ There are creatures in the service of human farce such as cow, buffalo, horse and donkey, birds (chicken and ducks And so on ..)
God says in the Holy Qur'an
8. And (He has created) horses, mules and donkeys, for you to ride and as an adornment. And He creates (other) things of which you have no knowledge.

2 - There are no creatures in the service of man and should be killed because they cause serious harm to humans
Such as talk of 'Aa'ishah said: The Messenger of Allah peace be upon him: «Five of the animals
Raven - Mice - Alhaddeeh - Dog Alakor – Scorpio
And similar to them
Like a snake And so on
is a consensus among scientists
. Should be killed, whether in Mecca during the pilgrimage, or normal times, in any place

Allah Almighty created animals for many rule .. The first is to serve man in his life, and then to work the natural balance In the ground ... And others

142. And of the cattle (are some) for burden (like camels etc.) and (some are) small (unable to carry burden like sheep, goats etc. for food, meat, milk, wool etc.). Eat of what Allah has provided for you, and follow not the footsteps of Shaitan (Satan). Surely he is to you an open enemy.

5. And the cattle, He has created them for you; in them there is warmth (warm clothing), and numerous benefits, and of them you eat.

66. And verily! In the cattle, there is a lesson for you. We give you to drink of that which is in their bellies, from between excretions and blood, pure milk; palatable to the drinkers.

80. And Allah has made for you in your homes an abode, and made for you out of the hides of the cattle (tents for) dwelling, which you find so light (and handy) when you travel and when you stay (in your travels), and of their wool, fur, and hair (sheep wool, camel fur, and goat hair), a furnishing and articles of convenience (e.g. carpets, blankets, etc.), a comfort for a while

68. And your Lord inspired the bee, saying: "Take you habitations in the mountains and in the trees and in what they erect.

69. "Then, eat of all fruits, and follow the ways of your Lord made easy (for you)." There comes forth from their bellies, a drink of varying colour wherein is healing for men. Verily, in this is indeed a sign for people who think

14. And He it is Who has subjected the sea (to you), that you eat thereof fresh tender meat (i.e. fish), and that you bring forth out of it ornaments to wear. And you see the ships ploughing through it, that you may seek (thus) of His Bounty (by transporting the goods from place to place) and that you may be grateful.

8. And (He has created) horses, mules and donkeys, for you to ride and as an adornment. And He creates (other) things of which you have no knowledge

and then to the work of the natural balance in the soil ... and others ...

.There are forests and deserts and remote areas and tropical
.
Man do not live in it

Man kills animals that live around him, which pose a threat to human life
But
Not search for them all over the world and kill them.
Therefore
There is no prejudice to the natural balance and defects in creation
