ABOUT THE USE OF THIS BLOG

LET ME EXPLAIN THE PURPOSE OF THIS BLOG. THIS IS AN OLD BLOG AND IT HAS GOT MANY USEFUL LINKS IN IT THAT WE WILL CONTINUE TO USE, WHEN WE VISIT THE BLOG. BUT TODAY WE WANT TO USE IT MAINLY TO WRITE A DIARY OF THE LIFE OF A NEW BORN BABY, WHENEVER THERE ARE THINGS TO SAY ABOUT IT. BECAUSE BLOGS NEED TO BE ACTIVE TO ATRACT VISOTORS, WE WILL ALSO WRITE AN OLD MAN LIFE STORY, WHICH ONE DAY COULD BE USED TO COMPARE IT WITH THE NEW BORN BABY, YOU SEE TODAY THINGS CHANGE VERY QUICKLY AND IT COULD BE INTERESTING TO SEE THE GREAT DIFFERENCE LATER. WE WOULD ALSO LIKE TO COLLECT OTHER LINKS LIKE BABY SONGS TO MAKE IT MORE BABY FRIENDLY.

The best way how to use this blog. To access personal site from same author, click of the picture above, to access some You-tube nursery songs click on the links below. You can also link to other sites; just click on any links that you find in this blog.

HERE I WANT TO ADD THAT EVERYBODY IS WELCOME, SO, FEEL FREE TO USE THE LINKS WITHIN THIS BLOG

Welcome to my blog, Mother Nature Challenge
and this post, Environment will change
-
On the Yahoo news today was reported that because of the global warming there will be adverse changes in the environment, hereunder is a copy of the report:

Conserving Australia's environment as it is today will become increasingly impossible as the world warms, so governments should instead focus on managing environments as they change, the CSIRO says.

A new report, released on Tuesday, says the impact of climate change on plants, animals and ecosystems will be "significant" by 2030 and "extreme" by 2070.

"This is likely to see the emergence of new environments and the disappearance of many existing environments," the CSIRO study states.

"The general pattern of change in vegetation is likely to be a decline in the area of environments that now favour trees and an increase in more arid environments favouring open woodlands, chenopod shrublands and grasslands."

Some species will persist where they are now geographically but their numbers will change.

Others will prosper in new regions and die out in others as climate change takes effect.

The report says current thinking about conservation - to preserve species and communities in their historical locations - will need to change.

"This paradigm of conservation will become increasingly unachievable and less effective for guiding conservation investment and actions," it states.

Instead there should be a preparedness to manage "inevitable change in order to minimise the loss of values associated with biodiversity".

A new concept of "dynamic biodiversity" could see a focus on the existence of species rather than their abundance and distribution.

The health of ecosystems could be the objective rather than fighting to preserve their existing composition and structure.

Australia's national science agency suggests the species-by-species approach will be more difficult to manage with a dramatic rise in the number of species vulnerable to extinction.

It could be a matter of "conserve the stage not the actors".

"Many of the environments our plants and animals currently exist in will disappear from the continent," lead researcher Dr Michael Dunlop said in a statement.

"Our grandchildren are likely to experience landscapes that are very different to the ones we have known."

We all hope that somehow our scientists find a way to minimize the adverse effects that this change will bring.
