in what way does....

animals are very useful to man...we can utilize them as our food, clothing and so on and so forth...we can have them as pet too like dogs and etc..

there are many ways that animals have their own usefullness to man ...like dogs...we have them to guard us and accompany us always in the house, we can also use them for clothing lines...where in their skin have been peeled off and dried..but this kind of system is not allowed now a days especially to extinct animals..its forbidden to kill those animals

One obvious way is we eat some animals and we use their fur for clothing that we make to wear.
