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.

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.

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
