Humans a tiny fraction of all life on Earth, but responsible for the destruction of 83 per cent of all wild mammals and half of our plant life. This the analysis of a new study from the Weizmann Institute of Science in Israel. The ground-breaking report the first investigation into the weight of every class of creature and life form on our planet. Lead researcher Professor Ron Milo what the research. He said: "I was shocked to there wasn't already a comprehensive, holistic estimate of all the different components of biomass." He the study will , "a perspective on the very dominant role that humanity now on Earth". There are 7.6 billion people on Earth, but they represent just 0.01% of all living things. Scientists say that the same percentage as for termites. However, since we walking on this planet, we have to cause the loss of most of its living species. Humans have also greatly the ratios of livestock to wild animals. Today, farmed poultry (mostly chickens) up 70% of all birds on the planet, with just 30% of birds wild. Similarly, 60% of all mammals on Earth are livestock (mostly cattle and pigs), while just 4% are wild animals. Professor Milo people will his study, "as part of their world view [and] of how they " He said he hopes people will less meat.
