U.N. report: Dire warnings on biodiversity and future of humanity (interview)

A million species could disappear

That dire warning comes from the latest extensive report from the United Nations.

They gathered scientists from around the world  to contribute to the first comprehensive report on the state of the world’s biodiversity.

The report indicates that unless immediate change begins, humanity itself could face serious challenges around the world.

The report says in no uncertain terms that nature is declining at a rate never seen before in human history.  The report was prepared by the U.N. sub committee, the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) and involved 145 scientist authors with contributions from hundreds of other scientists and researchers from countries around the world. The final report had to be approved by the 109 member countries.

At over 1,500 pages, it is expected to be released later this year

IPBES Chair, Sir Robert Watson, is quoted in the media release saying, “The overwhelming evidence of the IPBES Global Assessment, from a wide range of different fields of knowledge, presents an ominous picture,“The health of ecosystems on which we and all other species depend is deteriorating more rapidly than ever. We are eroding the very foundations of our economies, livelihoods, food security, health and quality of life worldwide”.

Habitat loss, and unsustainable practices such as overfishing, logging, and resource extraction are major problems.

Since the 1600’s almost 700 species with backbones have become extinct, while over 550 domestic animals used for food are gone, along with 40 percent of amphibians, more than a third of marine mammals, while nearly a third of sharks and fish are threatened with extinction.

Loss of forest cover is not just a concern in Canada's boreal forest but around the world including both legal and illegal clearings in the Amazon and around the world.

Professor Kerr likens the situation to that of humanity on top of a scaffold but knocking out the biodiversity support beams and waiting to see what happens.

The report notes 18 ways in which nature helps humans, but that 14 of them are declining including nature’s ability to provide clean air and water, and good soil.

Amidst the dire warning of the report there is optimism however. Professor Kerr notes that if each of us makes small individual efforts at conservation, or a slight change of diet, or travel habit, the cumulative effort will be very helpful. The report says that if concerted action is taken by governments around the world the predicted damage can be limited if not halted.

Netiquette »

When you express your personal opinion in an online forum, you must be as courteous as if you were speaking with someone face-to-face. Insults and personal attacks will not be tolerated. To disagree with an opinion, an idea or an event is one thing, but to show disrespect for other people is quite another. Great minds don’t always think alike—and that’s precisely what makes online dialogue so interesting and valuable.

Netiquette is the set of rules of conduct governing how you should behave when communicating via the Internet. Before you post a message to a blog or forum, it’s important to read and understand these rules. Otherwise, you may be banned from posting.

  1. RCInet.ca’s online forums are not anonymous. Users must register, and give their full name and place of residence, which are displayed alongside each of their comments. RCInet.ca reserves the right not to publish comments if there is any doubt as to the identity of their author.
  2. Assuming the identity of another person with intent to mislead or cause harm is a serious infraction that may result in the offender being banned.
  3. RCInet.ca’s online forums are open to everyone, without regard to age, ethnic origin, religion, gender or sexual orientation.
  4. Comments that are defamatory, hateful, racist, xenophobic, sexist, or that disparage an ethnic origin, religious affiliation or age group will not be published.
  5. In online speak, writing in ALL CAPS is considered yelling, and may be interpreted as aggressive behaviour, which is unpleasant for the people reading. Any message containing one or more words in all caps (except for initialisms and acronyms) will be rejected, as will any message containing one or more words in bold, italic or underlined characters.
  6. Use of vulgar, obscene or objectionable language is prohibited. Forums are public places and your comments could offend some users. People who use inappropriate language will be banned.
  7. Mutual respect is essential among users. Insulting, threatening or harassing another user is prohibited. You can express your disagreement with an idea without attacking anyone.
  8. Exchanging arguments and opposing views is a key component of healthy debate, but it should not turn into a dialogue or private discussion between two users who address each other without regard for the other participants. Messages of this type will not be posted.
  9. Radio Canada International publishes contents in five languages. The language used in the forums has to be the same as the contents we publish. The usage of other languages, with the exception of some words, is forbidden. Messages that are off-topic will not be published.
  10. Making repetitive posts disrupts the flow of discussions and will not be tolerated.
  11. Adding images or any other type of file to comments is forbidden. Including hyperlinks to other websites is allowed, as long as they comply with netiquette. Radio Canada International  is in no way responsible for the content of such sites, however.
  12. Copying and pasting text written by someone else, even if you credit the author, is unacceptable if that text makes up the majority of your comment.
  13. Posting any type of advertising or call to action, in any form, to Radio Canada International  forums is prohibited.

    The only contribution to save tuna is so simple, just don`t buy it anymore!!!

    I stopped it many years ago, but as long as we buy it, it will be sold.

    Our insects went down to 75% because of pesticides,

    we destroy worldwide our ecosystem.

    Sometimes I wonder how you can go to sleep after all these bad news,

    what are not really news anymore, they are facts since some time.
