96% of the mammals on earth are humans (36%) and their livestock (60% farm animals). Only 4% of worldwide mammals are considered to be wild animals any more.

Even more concerning is the loss of biogenetic diversity and biomass in the case of insects. A study published in 2017 found out about a "75 percent decline over 27 years in total flying insect biomass[...]" from 1989 to 2016. Do you believe this has gotten better?

These numbers sound very uncomforting

But the problem we as the human race have created go even much deeper

Up to 3% of global land mass is expected as urban areas including villages and cities. This wouldn't be a problem in itself. However, to feed the people living in these 3% the human race occupied way more landmass than that.

Agriculture dominates the human land use at most. About 37–40% of the terrestrial surface. Approximately 12% as Cropland and 25–28% as Pasture (grazing land for farm animals and livestock). 

30% of the worldwide forests are used for production (primarily forestry, wood industry). There are countries with especially high percentages and some with lower usage by mankind. So far we have to protect the most endangered biospheres around the globe.

This ultimately adds up to a real high percentage of intensively used land by humans.

To achieve this we all have to change our behaviour, buy less products, buy local, buy products that might at least have a little positive impact on the environment.

Even our products leave a small footprint on the earths eco systems but at the same time they help to preserve unique pieces of land from further exploitiation by humans. Read more about this topic.
