Plant trees2. Protect the forest3.Walk / Ride a Bike. Sometimes, its not necessary to take a car everywhere you go; walking or riding a bike is a great way to get some exercise and reduce your carbon footprint to help save the earth.Unplug Unused Electronics. Even unused electronics can suck up energy unplug rarely-used items to reduce energy consumption and your electric bill. Its a win-win.Use Public Transportation/Carpool. If walking or riding a bike is out of the question, mass transit and/or carpooling causes less strain on the environment and puts a smaller dent on your bank account.Keep Old Electronics. E-waste is a growing concern, especially when industrialized countries send old electronics to poorer nations, harming both the impoverished individuals who salvage them and the environment that must sustain the waste. Try not to upgrade to the latest version of any gadget you have if the device you own continues to work well. If you need to, though, deposit your old version at an e-waste collection center.Grow Your Own Food. Having your own garden is a great way to eat organically, avoid genetically modified foods, and reduce the need for polluting farming equipment and substandard irrigation methods.Use Reusable Shopping Bags. Plastic bags arent biodegradable, meaning nature cant break them down, and they often end up ravaging animal habitats or polluting waterways. Instead, use a cloth or canvas bag when doing your grocery shopping.Use LED Light-bulbs.LEDs are more energy efficient than regular incandescent bulbs. In fact, they are 75% more efficient and last 20-25 times longer. This is a no brainer, save the planet and save your cash!Skip the Bottled Water. Opt for a reusable water bottle to save money and help the environment. Besides, tap water is already stringently monitored by the government, so bottled water isnt necessarily safer.Buy Sustainable Products. When growing your own food isnt an option, you can let your money speak for you. Buying sustainable products is a great way to help the environment. Supporting your local farmers market, only purchasing items that you need or repairing items that you already have, buying reusable or recycled products, and investing in appliances with EnergyStar ratings are all great ways to buy sustainably.Pick up trash. Notice all of the trash on the sidewalks or on the road? Take a moment to pick it up and throw it in the trash or recycle it. Make it a habit on your walk to work to bring a bag with you to fill with trash or simply drop it in the closest trash can. If everyone picks up a couple pieces of trash each day the world would be a much cleaner place.Recycle. Recycling is a classic way to help the environment, but not many people know exactly which items can be recycled. Glass, newspaper, aluminum, steel cans, plastic, food and yard debris (compost), corrugated cardboard, motor oil, and batteries are all items that can be recycled at community recycling facilities. To find out what items can be recycled in your community, contact your local waste management.Reuse. Simply reusing old items can help protect the environment. Glass containers can be used for storing food or other items, cereal bags can be used in place of Ziploc bags, and old or unused items can be sold in a yard sale; its about finding alternative uses for items so that waste can be reduced. ecosystemoverseasregioncontinentmillionlengthn. 生态系统adj. 海外的，国外的adv. 在海外，向国外n. 地区，区域；行政区n. 大陆，陆地，洲num. 一百万；许多，大量n. 长，长度；时间的长短； 篇幅，(电影)片长Words and expressionsWords and expressionsWords and expressionsWords and expressionsbiodiversityspeciesnutbrazil nutlilywater lilyvarietywildlifebeneathn. 生物多样性n.
