These regulations are already being phased in. Yes, it's real, and coming soon. It is already in place in New Zealand, where it costs NZ$30,000.00 (currently about US$23,600.00) to get permission to import a single species! Read about it in the New Zealand Herald.

Missouri Botanical Garden W3Tropicos Database.
Even though the Missouri Botanical Gardens is severely compromised by funding from Monsanto, there are still many people there doing important work. But whatever you do, don't believe a word that MBG director Peter Raven says about genetic engineering - in this respect, he has been described as "a paid traveling salesman for Monsanto" and a "wolf in sheep's clothing", and he is spreading disinformation on genetically-engineered crops by carefully avoiding or dismissing the many serious issues surrounding them. He has gone so far as to accuse those who oppose the unrestricted and unregulated spread of genetically-engineered plants as spreading "economically-motivated disinformation", and that they are guilty of "a serious crime against humanity." Yes, Peter, I agree—those who spread "economically-motivated disinformation" are guilty of "a serious crime against humanity" - particularly those who do so in the service of Monsanto. Time to have a heart-to-heart conversation with the man in the mirror, Peter!

Free peer-reviewed science on the web! Great stuff!

Digital Privacy and Security

This section is a work-in-progress, and I'll be adding things as I learn about this subject myself. Your comments and suggestions are appreciated!

Q: "What do you have to hide?"
A: "None of your business!"

So, if you aren't doing anything wrong, why do you need encryption? Well, everyone does! You don't have anything illegal in your home, but you still have a lock on your front door, and no one thinks you are doing something nefarious because you lock your door, or draw the curtains now and then for privacy. You have all sorts of perfectly legal and innocent things you may want to hide - that list of holiday gifts, for example, or those plans for a surprise birthday party for your spouse. And then there are those things you really should hide - your new business plan, business trade secrets, your medical records, and your bank account numbers, financial, and tax records (which have that all-important Social Security number so loved by identity thieves!). Your computer is a very vulnerable thing, especially whenever you are on-line. Protect yourself! You wouldn't go online without an anti-virus program, and you shouldn't own a computer unless you have good encryption programs. In this day and age of rampant identity-theft and other cyber criminals preying on the innocent, you need to become security-conscious.

Very serious free encryption program for single files and e-mails. Use this and you can e-mail securely. Need to e-mail your credit card number to someone? Use PGP/GPG! Use it for all private communications. Also useful for people living under totalitarian governments.
http://gnupg.org/ Home site
http://gpg4win.org/ for Windows
http://gpg4win.org/download.html for Windows
https://gpgtools.org/ for Mac
http://futureboy.us/pgp.html - Good PGP tutorial, has lots of command-line stuff that most of us won't need, but scroll through it for gems like his "Good Encryption Practices", and "Why Public-Key Encryption is Cool", and how to hide encrypted files in photos or music files.
Here is my GPG public key you can use to send me e-mails or files that only I can decrypt. As Alan Eliasen says "Pretend we're interesting and send me encrypted e-mail."!

Serious, free intelligence-agency, military-grade disk encryption, approved by the US National Security Agency as "sufficient to protect classified information up to the Top Secret level". Choose from AES (Advanced Encryption Standard), Twofish, Serpent, and combinations of these. Unencrypts only into RAM, so it isn't stored elsewhere on your hard disk. Can create hidden partitions that have "plausible deniability". Useful for sensitive personal and business records, as well as for people living under totalitarian governments.

UPDATE: Recently (May 14th, 2014) the anonymous developers of TrueCrypt took down the download site, claiming TrueCrypt is no longer secure, and only allow downloading a crippled version that will decrypt only, advising users to migrate to Bitlocker, a Microsoft program. There has been much speculation on this (demands from the NSA, etc.), but an independent audit of the program (not yet completed) has found no vulnerabilities or back-doors, and many recent cases have shown law enforcement (including the FBI taking 12 months on one file!) were unable to decrypt TrueCrypt files - search on "TrueCrypt legal cases". You can still download it from Switzerland at truecrypt.ch.

Digital Privacy Laws.

DNA Privacy - How Secure is your DNA?
Interesting information on DNA privacy, laws, and protecting yourself. Other interesting information on privacy, background checks, cyber-security, etc.

Electronic Frontier Foundation.
Good information on protecting your digital privacy. One of the best!

Free program that securely erases files from your computer by writing zeros over them. You thought that "deleting" a file gets rid of it? No, it is still on your hard disk until it is written over, and can be easily recovered. Throwing away or donating an old computer to the thrift store? Identity thieves can recover all kinds of "deleted" files from your hard disk, and have been known to recover credit card numbers, passwords, bank account numbers, and all kinds of sensitive data from discarded computers. Don't believe it? Try out the free program "Recuva", and you will be surprised at how many files you can recover, even from a reformatted disk!

Well, I was wrong! They give fake info on the exact locations of the weather stations, probably to foil vandals. Still a great service, and a government program I can support—but jeeze, is there anyone in government not lying to us?
