The mass of an object is how much matter it has. It doesn’t change with location and is constant. Therefore, our mass on the moon and on the earth would be the same.
Biomass is the combined mass of plants, animals, people, and other living things (including bacteria and fungi).
A recent study found that manmade objects’ mass outweighs the earth’s biomass for the first time.
To get to the results, the study authors divided manmade objects into broad categories: concrete, bricks, asphalt, metal and other materials like plastic, wood used for building, and glass. They referred to the manmade mass as ‘anthropogenic mass’.
The anthropogenic mass has been compared to the current biomass which equals approximately 1.1 teratonnes. The conclusion of the study is that 2020 is a crossover point when manmade mass outweighs natural mass for the first time.
This has happened because the anthropogenic mass has doubled roughly every 20 years in the recent times.
