How environmental problems can be local, regional, or global?

and please provide one example for each.How environmental problems can be local, regional, or global?Environmental problems can be also classified as local, regional or global on the basis of the area which they are effecting.....



For example:

A small place in delhi like rohini or pitampura is facing water shortage.This problem is not faced by any other state or country then it's a local environmental issue.....but if a whole state like uttar Pradesh or India is facing water shortage then this problem is regional i.e. effecting a particular region. And is this problem is faces by the world globally.....then this problem is Global.

Example of local....

gurgaon faces electricity shortage..

India also face on a whole electricity shortage.

The world faces Global Warming.How environmental problems can be local, regional, or global?
a factory ,or town polluting around itself is Local

the east coast hurricane damage was regional

climate change or sea levels rising is global



collectively it is all Global because we live in a closed system

for example



Mercury levels in polar bear meat and fish is extremely high, As the sea ice melts, a toxic stew of mercury and synthetic chemicals is seeping into the Arctic food web, harming the area's people.



When coal is burned in power plants in the U.S., China and elsewhere, mercury is released into the atmosphere. Airborne, mercury can travel great distances before settling to the ground.



So here a local contaminating factor has become global.How environmental problems can be local, regional, or global?Every day we are creating problems but no solutions for it in my view
