Want to protect the environment? You probably can't fix everything on your own, but by taking small steps and keeping the environment mind every day, you can make a difference.
Firstly, think green. Challenge yourself to think about the environment as you live your life. you turn off the lights when you leave a room, you'll save energy. If you take shorter showers, you'll save water. Never pour （clean）water or waste into soil or nearby rivers.
Secondly, shop green. （shop）is fun, but buying things you don't need is wasteful and （real）bad for the earth. Thoughtless consumption is the main cause of serious pollution in many places. Before you buy something, ask （you）whether you'll use it. Keep yourself away from （buy）products with unnecessary packaging.
（three）, dress green. Try to choose eco - friendly clothes that won't harm the environment. But what really matters isn't the colour；it's how the clothes （make）. No matter where you shop, keep eye out for products made with environmentally friendly materials like organic cotton, grown without pesticides.
