Essay of three important Animals (edited)

Many animals in our society improve our life for different reasons, for example, cows give us milk and meat, the chicken give us eggs and meat, we can make a leather cloth from animal too. However, there are some animals might become three most important animals to our society, and I'll describe them in my essay.

The first animal is the chicken. Mainly people like chicken because it delicious and they don't have much fat. Muslim, Jewish, and Hindu people who can not eat beef and pork are also able to enjoy chicken.

Some bird's feather has been used for a cushion.

Secondly, fish is very popular food as well. Tuna and salmon are used for Sushi and Roll around the world and is low fat meat too. Another case, a scientists discovered cure for cancer lately from the blood of horseshoe crab, which are living shallow ocean around Caribbean sea since 144 million years ago.

And last but not least, dogs are important animal for support people' s job, for example they help to identify drugs at airport by their sensitive nose, and sometimes they're able to find people who have survived under rubbles after earthquake. Generally a lot of people have their dogs because they are very friendly, faithful, and some of them can protect house.

Therefore, many animals are necessary for our life and they certainly help our society which means perhaps our community is difficult to live without them.
