Did you ever think of how humans compare in proportion to all other life on Earth?
Here is a mind blowing comparison in chart form, compliments of VOX.
As you can see, humans make up only 0.06 Gt of Carbon. However while humans represent only a small fraction of biomass on the Earth, we are reducing the rest of animal and plant life in staggering amounts. While plants still represent an overwhelming majority of the bio-matter, it is estimated that plant mass used to be approximately DOUBLE what it is today on Earth before humans started clearing forests for agriculture and human living.
