Among his various "cures" for the planet's fever are:
1) A "meat patch" that makes you puke when you eat meat.
2) Hormones that stunt your children's growth.
3) Drugs that make you want to write checks.
4) Genetically engineering humans with "cat eyes" so we don't need light bulbs.
Of course, Matthew assures us that no one will be forced to do any of these things. The government will simply set limits to how much carbon your family can produce or set drastic limits on consumption. Then you get all the freedom you need to decide whether you want to have 2 really small children, or one medium sized child, or perhaps one large child who will be required to wear a "meat patch".
Progressivism! Enhancing your freedom – by limiting your freedom!
