How can I word this radio presentation better?

Question

Good morning ladies and gentlemen today we are going to talk about global warming and the effects it is having on polar bears and their habitat. In the last 20 years the polar bears population has shrunk more than 20 percent which leaves them with small numbers of about 20 000. If the population keeps shrinking like this soon polar bears will be an endangered species, maybe even extinct. Global warming is causing many extreme climate changes such as droughts, torrential rains, shrinking Arctic ice and glaciers, and rising sea levels.

Answer 1

First of all, you should ask yourself if your radio address is fictional or are you interested in the truth.  The truth is Polar Bear population have not shrunk by 20 per cent.  That is a blatant lie or misrepresentation.  As the actual number became better understood, the number increased.  

Despite Time Magazine and the rest of the media’s unfounded hype, polar bears are not facing a crisis, according to biologist Dr. Mitchell Taylor from the Arctic government of Nunavut. “Of the 13 populations of polar bears in Canada, 11 are stable or increasing in number. They are not going extinct, or even appear to be affected at present,” Taylor wrote on May 1, 2006. See: http://www.thestar.com/NASApp/cs/Content...

Answer 2

Everyone associated with the media has a target audience. So your aiming your statements at a selective viewership. Hence you are limited to that viewership only. Are you going to make a factual statement or one based only on generalizations...it will make a difference. You can obtain free computer based frequencies(home based) for local media now. I believe the bill of enactment was about three years ago.

Answer 3

Global warming will affect climate directly, not polar bears.  Change the first sentence to talk about climate change.  Climate changes will affect more than just the ecosystem polar bears live in.  It can change the species composition of almost every ecosystem.  Malaria and dengue may pop up in places it is not often seen in, forest will change (could become tropical, savannas, and range extend northward), even ocean currents can be affected.  Make the point that ecosystems may change in unpredictable ways.  Then go with the polar bears as an example.  The population is not listed as endangered because of low populations, like is normally done.  There is a healthy population right now, but future PROJECTIONS are not so good.  It is listed as endangered because sea ice has significantly decreased because of climate change induced by anthropogenic global warming and it is only expected to continue.

Looks like you know this.  Just equate climate change with anthropogenic  global warming.  Global warming is fact (it is observable).  Some people incorrectly think it is all natural, but scientist have high confidence that it is caused by human activity.  Here is a link from the Nation Academy of Sciences to a newly released summary to help you wade through the propaganda out there.  Can take a minute to load.

Answer 4

I recall a similar broadcast beginning like this:

"We know now that in the early years of the twentieth century this world was being watched closely by intelligences greater than man's and yet as mortal as his own..."

Answer 5

Good morning ladies and gentlemen. Today's topic is  global warming and its effects on polar bears and their habitat. Global warming is causing extreme climate changes, and the Arctic, where the polar bears live, has experienced droughts, torrential rains, melting ice, receding glaciers, and rising sea levels.  As a result, in the last 20 years the polar bear population has shrunk more than 20 percent, diminishing their numbers to only around 20 000. If the population keeps dwindling, soon they'll be an endangered species and face possible extinction.

EDIT:

The question was not about content, but about the wording. Let him/her do his/her own research and don't be so rude!

Answer 6

I believe that you need to research the issue BEFORE you broadcast!!

"The U.S. Geological Survey (USGS) on September 7 claimed that two-thirds of the world's polar bears may die by 2050 due to global warming. Such claims are strongly contradicted by real-world evidence.

There are currently more than 25,000 wild polar bears in the world, and their numbers are growing – not declining – at an explosive pace in this time of "unprecedented global warming." According to the February 7, 2005 Edinburgh Scotsman ( http://thescotsman.scotsman.com/internat... "The world's polar bear population is on the increase despite global warming.

"According to new research," the Scotsman reports, "the numbers of the giant predator have grown by between 15 and 25 per cent over the last decade.

"We're seeing an increase in bears that's really unprecedented, and in places where we're seeing a decrease in the population it's from hunting, not from climate change," Canadian polar bear expert Mitch Taylor told the Scotsman.

The March 9, 2007 London Telegraph confirmed the ongoing polar bear population explosion ( http://www.telegraph.co.uk/news/main.jht... "A survey of the animals' numbers in Canada's eastern Arctic has revealed that they are thriving, not declining," the Telegraph reports.

"In the Davis Strait area, a 140,000-square kilometre region, the polar bear population has grown from 850 in the mid-1980s to 2,100 today," added the Telegraph.

Indeed, polar bears evolved from brown bears anywhere from 200,000 years ago ( http://www.alaskazoo.org/willowcrest/pol... to 3 million years ago ( http://www.bbc.co.uk/nature/wildfacts/fa... They survived at least one period when polar temperatures were at least 6 degrees Celsius warmer than today ( http://en.wikipedia.org/wiki/Image:Ice_A... and perhaps temperatures as warm as 15 degrees Celsius warmer than today ( http://www.ctv.ca/servlet/ArticleNews/st...

Given that polar bear numbers are rapidly increasing and that they survived substantially warmer periods than is expected anytime in the foreseeable future, it is safe to dismiss this latest global warming scare as little more than fantasy."

Sorry, but I prefer facts over fiction myself!
