what is the impact of disasters on our ecosystem?

Question

i am MANU DEV from ARMY SCHOOL KIRKEE PUNE , i am a student of class 9. My teacher has asked me to make a project on the topic :-impact of disasters on our ecosystem

Answer 1

Well there's "run off" for one...
Think about it, in a disaster everything in a house hold or factory gets mixed in with the environment (that means pollution), it's kinda like Run Off from the street, but in stead it's alot more of it, and is not just from cars, tanted water, or stuff like that...
It's a much bigger prob.

It's more messy then the human clean up (picking up broken peices of houses and stuff).

Answer 2

Generally major disasters become an opportunity for less successful
species to thrive while other species lose out - either due to being
outright killed or due to starving or loss of habitat.

The usual example of this is that mammals wouldn't have thrived
as much as they have if the dinosaurs were still alive. If a large
meteor did wipe out the dinosaurs, the effect of that metor was
to make large mammals (such as us) possible.

Usually, we defined "planet killer" meteors as ones that would wipe
humanity off the face of the Earth. However, you can well imagine
such a distaster eliminating us but leaving a viable environment for
some other animal to take over.

To completely eliminate all life would probably require poisoning the
planet - vs changing its temperature, etc. There are many forms of
life out there that have evolved to handle many different circumstances.
I would be hard pressed to think of a natural disaster that could kill 'em
all off.
