I’ve been thinking about eating less meat in general, too, though what you’ve mentioned is another great reason to do so.

They do have toilet flaps that put less water in the bowl, so you may want to look into those — no new toilet required.

You can recycle 80% of what you buy? That’s impressive. I’m sure I can improve on buying more goods that are recyclable.

Here is how I’m doing things to help out with the planet.
1. I don’t own a car.
2. I take mass transit when I have to.
3. I walk a lot. I walk from the house to transit and then from transit to work and then out to do groceries on the weekend.
4. I use energy efficient appliances. I also use cold water as much as possible in the washing machine and now I’ll be using the clothesline instead of the dryer more often.
5. I recycle about 80% of my stuff.
6. Compost. Now with the garden, all the food waste will come in handy!

Room for improvement:
1. low-flow toilets. I have the standard kind and I know I should use less water.
2. better insulation in the house. I know I can lower my energy bills just with a little more insulation.
3. less meats and more veggies. we eat in a lot and I take lunches at lot. still, the energy it takes to make meat vs. energy to make veggies makes going more vegetarian more sensisble. I don’t think I’d be a full out vegetarian but definitely reduce the meat consumption by a third.
