  • If Bigger Creatures are Wiped out Climate Change could become Worse than Before

According to the latest news, if bigger creatures are wiped out, climate change could become much worse than it was before.

The extinction of larger fauna from the rainforests could considerably speed up the process of climate change. Researchers at the University of East Anglia have found that a sharp downswing in the populations of fruit-eating animals was causing tree degradation.

These creatures included: monkeys, birds and pig-like animals. These large animals served as the dispersal agents for large-seeded trees that had high density wood.

These trees are fine plants that capture the stray carbon dioxide from the atmosphere and trap it in their core structures. The large trees are also better at their job than the smaller trees.

And with their disappearance due to the extinction of the large animals, the conservation efforts have gotten all botched up. The larger animals eat the seeds of the fruits of these trees and these seeds pass on into the soil humus via their stools.

By the extinction of these animals, the natural ecosystem is turned on its head and goes topsy-turvy. This of course can have dire consequences. Lesser fixing of the CO2 is a sad thing indeed.

It means that climate change will be accelerated. Several of the large birds and mammals face the dire danger of poachers, hunters and loss of their ecological niche.

The decline of these large creatures may spell the doom of the rainforests as we know them. And everybody knows that the rainforests are the lungs of the planet.

More than 2000 tree species in the heart of the Brazilian rainforest were studied extensively for the sake of climate change prevention. And 800 animals were observed as well. The results were pretty conclusive.

The main problem remains the small fruit-eating animals such as bats, tiny birds and marsupials. This is because they only eat small seeds and thus do not help in the dispersal of large seeds.

And the large animals such as primates, toucans and tapirs are beginning to enter the endangered species list. Thus this is a double tragedy which is taking place.

Not only are we losing charming creatures but upsetting the delicate food webs that interconnect nature in the raw. Meanwhile, deforestation continues in its devastating pace. Things will have to be controlled unless we want a widespread catastrophe and disaster on our hands.
