Simple-by losing an animal forever means at least a small proportion of the Ecosystem is in danger and the Ecosystem has faded a little. Every animal, plant and life-bearing tree, makes a difference. Also, won't mice be more common?
What would happen if all the bird's disapear?
It is hard to even imagine the consequences; however, a review of what happened in China could
be instructive:
In 1958 Mao Zedong declared sparrows an enemy of the state. He had decided that the birds
were the reason for the failure of his agricultural programs and, hence, farmers were given
incentives to kill all they could find.
Amazingly, they succeeded. When tens of millions of peasants go to work, billions of birds can be
killed in a season. And not just sparrows: Photographs in history books show twenty-foot high
stacks of birds of many species-and a lot of happy government officials.
But nature abhors a vacuum.
The photographs from the next year show a genuine plague of locusts. Without their natural
predators, grasshoppers were able to reproduce to the point they blotted out the sky and
blanketed the fields from one end of China to the other. (Estimates are that at least thirty million
people died in the immediate famine and the resulting environmental and societal consequences
are too disturbing even to describe here.)
There will be a famine if all bir's die? No, certainly not.
We live in an advanced technological society with many agricultural companies that can follow
the spirit of DuPont's "better living through chemistry." Of course, few Americans would welcome
the use of more pesticides.
Which could be a problem. One of the consequences of ecological imbalances is great
population growth for some lucky species. Rabbits live a safe life in Chicago parks, regularly
eating their way through hundreds of thousands of dollars of vegetation. The forest preserves in
some areas are overrun by deer whose only predator is a speeding car. And everyone is
certainly familiar with the problems created by the over-population of Canada Geese.
Birds eat bugs.
Thousands every day of insects, worms, lice, beetles, moths, weevils…... the list is almost
endless. Purple Martins eat thousands of mosquitoes every day, for example. Evening
Grosbeaks will eat fifty thousand caterpillars in a summer.
Birds are our chief ally in keeping bugs in check. Most insects have a beneficial role in nature too,
but, without predators, they multiply at such a rapid rate that they will devour grass, leaves and all
other plant life.
The role of birds in the c ycle of l ife is simply irreplaceable.. There is my large statement to what would happen to the world and ecosystem if this occured.
The bug population would increase exponentially which would in turn lead to an increase in human deaths via poisonous bites (due to a higher rate of interaction) and the spread of disease such as malaria.
The population of mice, voles, and other small rodents would increase.
Then the higher predators would have little food and the snake's prey would over populate
Owls, like all water-dependent species, would be hard pressed to survive a drought. They would have to redistribute themselves to search for water.
The Lemming population would explode and we would be without a very pretty owl
There would be nothing for other animals to eat. so then those animals would die and then every animal will start dying.
Predators that eat specifically Snakes and Rabbits won't have enough food to eat and if Predators are not eating any others that they don't eat, other animal's population will increase
they would be fat
It would be sad.
It's not. Currently listed as "Least Concern" by the IUCN.
If the deer became extinct then ,all the greenery would overgrow , and all the animals that eat the deer would die as well because the deer was there main food source.
If the Northern leopard frog were to become extinct it would break the food chain. That would cause a collapse in the ecosystem.
If they went extinct the whole food chain would be out of balance.
they would be fat
It would be sad.
other animals that relied on it would die and come extinct
they would ALL be dead!
It would effect the food chain and other marine life would become extinct
what will happen if allegator snapping turtules
we would die
If all wild cats went extinct, then the prey it ate probably would rise rapidly in its population.
yes it whould mean to meny fish and shaks
the jellyfish it eats will get over populated
We would miss them so much
