climate change it natural but mankind is speeding it up

forest can rebuild its self as intended in nature

Answer 2

Mankind itself

we are our worst enemy

http://answers.yahoo.com/question/index;...

deforestation (done by man)

leads to desertification

changes in local climates

loss of species changes in Eco systems

droughts,water production,loss of soil



but the effects are much slower than

Hurricanes ,Volcanoes ,done By nature

Answer 3

I would say the sky because we are creating pollution which is causing violent hurricanes due to the increase in temperature in the ocean, floods from the water level increase from melting glaciers, and climate change due to the fact that there is a giant hole in the ozone layer from all the heat which allows harmful rays from the sun to the earth giving more skin cancer and so on. Now the most destructive is ourselves because we created so much pollution and we didn't really stop until this happened. Now natures just telling us what goes around comes around and kills many people....

Answer 4

All of the things you list there are local except 2, maybe 3.  Pollution and global cliamte change are the ones to worry about becasue they are a global problem on a global scale.

A super eruption (super volcano) could be a global event as well but i would be more concerned of the other 2.

Answer 5

All of the options could be just as fatal as one another depending on the severity of the event.

Answer 6

i agree with leoness. Anything can be destructive on God's Planet. Like for Example: Bad health, Humans, Natural Disasters, Climate change, Global warming, Natural renewable like gas, coal,etc, and objects from outer space.

Answer 7

Does sky include collisions with objects from outer space?  If so, then that's the one!

Answer 8

mankind is most destructive to mankind

Answer 9

Id say Sky because lots of pollution stays in the atmosphere and sun-rays stay locked up in Earth like Venus's Methane and other greenhouse gases that cause climate changes and endager the envirement.The climate is changing so dramatically the Greenland is getting smaller and so is antartica .And from years now from the ice melting, places will get flooded and polar bears will be extinct from not getting in cool places.
