What is the role of animals and humans in seed dispersal?

Animals play a transport role in the distribution of seeds, plants, around the globe. So burdock seeds, clinging to the animal’s fur, can travel a long way before they fall to the ground and begin to germinate there. The birds, having eaten the seeds of the fruit, carry them to an even greater distance. But the primacy in the transfer of seeds is occupied by a person. He cultivates different types of plants in different parts of our world. Taking a mango seed in Thailand, a person can plant it, even in Australia.
