Animals are of immense importance to our economic activity. They are a key area in the production of vegetables and fruits, as well as other food sources. A simple fact is that without animals, our world would be drastically different. The process called pollination is an important job that animals do in order to help produce the food we eat. This simple task is crucial for many agricultural products which help sustain life on earth.

Animal agriculture is an essential part of the food chain, and animal scientists have a major role to play in this. Farm animals provide us with important nutrition, and breeding programs have been developed to ensure their health. Exotic wildlife also plays a large part in the agricultural sustainability of our world.

Certain animals such as bees, cows, and horses are necessary for the continued growth of our food sources. However, companion animals such as dogs and cats also play a large part in promoting mental health benefits. Studies have shown that having a pet can help with many mental health problems such as depression, loneliness, and stress. Having an animal companion can provide companionship, comfort and even potential physical health benefits. Scientists have found that people who have pets tend to have lower blood pressure levels than those who do not own any pets. This indicates that the companionship of a pet has positive effects on human health which extend further than just emotional support.

Animals play an important role in food security, providing high nutritional value and contributing to agricultural sustainability. Animal products, such as meat, milk and eggs are valuable contributions to human diets when consumed in moderation. In the developed world there are several reasons why animals are so important - from providing companionship and a sense of purpose to helping reduce stress levels. They also provide natural pest control by eating insects which help maintain a healthy environment for other plants and animals. Furthermore, animals can help farmers with crop production by providing manure for fertilizer or pulling ploughs or carts.

For centuries, animals have provided humans with food in the form of animal foods, such as meat and dairy products, and seafood products. They also provide important sources of nutrition for people who cannot afford to buy nutritious food. Animal production plays a key role in helping to meet the significant demand for quality protein sources worldwide and combat hunger. Animals have a critical role in providing meat that is essential to many diets around the world. They are also important sources of income for farmers who rely on livestock as their main source of livelihoods.

Animals are valuable assistants to humans in a variety of ways. They provide comic relief, as well as companionship and affection. In addition, they help us to fill an otherwise empty natural environmental niche, performing jobs that no other creature could do in our stead. Without the domestication of animals on farms, there would be no natural ecosystem for them to inhabit and contribute their unique gifts.
