7.Have you considered having a meat-free night one day each week?One day out of each week isn't much.This little change is so simple that anyone can do it,and so important that everyone can make a difference.
According to the climate experts,livestock (牲畜) are responsible for 18% of the world's greenhouse emissions (排放物).If everyone in the USA had ONE meat-free night each week,it would mean the energy of 12billion fewer gallons of gasoline each year.That's a lot saved!
Without all the land cleared for farming animal food,and without all the fuel spent on transporting animals and meat around,you already know that cutting out a little meat is good for the planet.
What about you and your family?How can a meat-free night improve your health?
Plant based foods are naturally low fat,low cholesterol (膽固醇),high in vitamins,rich in minerals and full of healthy fiber.Fiber not only helps your to feel full faster,but aids in healthy digestion as well.Many useful minerals such as iron,calcium and zinc are also found in abundance in certain leaves,seeds and nuts.Studies have repeatedly shown that a high-vegetable but low-meat is very beneficial.Notice it didn't mention cutting out all meat,just lowering it!Eating some meat is still good for you.
Now that you know the benefits of adding a meatless night to your schedule,what steps can you take to actually enjoy it?
There are plenty of recipes where you won't"miss the meat"that don't require tofu or other meat-substitutes.If you are worried about not feeling full or not getting enough complete protein from the meal,why not add beans to it.Beans have complete protein just like meat,but they have no flavor of their own.You can add them to almost anything without changing the taste,and you can't hate them because there is no flavor to dislike.
It's up to you to have the fun of discovering great meat-free recipes.Recipes of all types are so easy to find with a simple search,and you never know what you might discover.Maybe you'll even find your family's new favorite meal!
