“The mass of humans – the sum of the body weights of all 7.5 billion people on Earth – now comprises 32% of the total mass of all vertebrates (mammals, reptiles, birds and amphibians) on land. Our domesticated animals, such as cattle, pigs and sheep, comprise another 65%. That is, humans and our domesticates comprise 97% of the mass of all terrestrial vertebrates – leaving only 3% for all of the Earth’s wild terrestrial vertebrates.”

Hell of an obesity problem.
