According to a new study, researchers have said that mammals and the birds will shrink in size over a period of the next 100 years.
According to the study titled ‘Nature Communications’
“Ecological downsizing can entail the loss of unique ecological functions and can impact ecosystem structure, function, and bio-geochemical cycles. Hence, downsizing could be a driver, as well as a consequence, of global change with implications for the long-term sustainability of ecological and evolutionary processes.”
The researchers have also clinched that the rate of extinction in animals has increased because of the recent activities of human beings. This has led to the increased capability to change the structure of mammals and the birds on earth. This will eventually lead to the worst ecological consequences.
Because of being targeted for their ivory tusk, the African elephants are today born without a tusk. They have inherited this trait for ensuring their survival in a world where they are being killed for the ivory.
The study has also mentioned that the total mass of the mammals will clearly decrease by as much as 25% in the next 10 years. The difference is significantly more than the 14% of body size decrease the mammals went about 1,30,000 years ago.
This study was organized with respect to the body mass, litter, size, diet, habitat, and the length in time between the generations in approximately 15,484 birds and mammals.
According to the International Union for Conversation of Nature (IUCN) Red List of Threatened Species, there are certain species which will extinct.
The species which are endangered have only a 1 % chance of survival while the endangered animals have a two in three survival rate. Animals which are most vulnerable are the safest with a survival rate of 90%.
The lead author, Rob Cooke, of the study, said “By far the biggest threat to birds and mammals is humankind—with habitats being destroyed due to our impact on the planet, such as deforestation, hunting, intensive farming, urbanization and the effects of global warming.”
The findings of the study also concluded that the small, fertile and adaptable species have high chance of surviving when compared to their other larger counterparts.
So, what do you think? Do we still need to do more damage to our planet to realize that we have already destroyed it enough?
