D Finding solutions 1 Read the article. Then check (/) the chapters that might be in Chelsea Thomson's book. 1 ]How to Use Less Energy 5 LHOW to Have More Garbage 2 ]How to Waste Time 6 ]How to Use Your Car Less Often 3 ]How to Recycle More 7UWhere to Buy Local Food 4 ]Buy More Than You Need 8 | Kinds of Food You Can Grow at Home Dear Readers, My new book, Going Completely Green, is finished! As the title says, I decided to go completely green for a month - no electricity, no running water, no car, no phone, no computer! I didn't even use anything with batteries. It was very difficult, and I decided to write a book about my experience. During the day, I wrote on paper with a pencil. When I wanted to sharpen my pencil, I remenmbered my pencil sharpener uses electricity. T had to sharpen it with a knife! At night, I used a candle for light. I washed all of my clothes by hand with water from the river behind my house, and then I put them on a clothesline to dry. I walked to a local farm to buy food. I ate mostly fruits and vegetables. I only ate meat about five times, and I cooked it over a fire in my yard. The hardest part was not talking to friends and family on the phone or emailing them. My best friend lives an hour away by car, so l didn't communicate with her at all. In my opinion, it is impossible to live completely green for a long time, but there are many things you can do. Now, I try to work with the lights off for most of the day. I'm driving my car again, but I try to walk or ride my bike when I only have to go a short distance.I buy more local food now, too. I have to use my computer for work, but I use it for fewer hours each day. l also turn it off when I'm not home. There are many things you can do to use less energy and water. This book will help you learn how to live a greener life. If you follow the steps in my book, you'Il really help the environment. Oh, and if you buy my book, you might want to read it by candlelight to save energy! Chelsea Thomson 2 Read the article again.
