Easy Ways to Green up Your Life

1. Eating meat produces greenhouse gas emissions(排放）。If you can't give up meat completely,you can reduce your consumption or give up beef.Don't eat out-of-season farm

products.They are grown in greenhouses.A lot of energy goes into heating the greenhouses.And shipping such out-of-season farm products by air from remote places consumes huge amount of energy,too.Just look for local and in-season foods.

2. Spend less time behind the wheel,cycle and walk more,and use public transport more.If you have to drive,the first thing is to choose a car that uses comparatively less fuel.Besides.

stick to the speed limit,keep your tires properly filled with air,empty your trunk of heavy items,and accelerate and brake gently.

3.Want to take a vacation trip by plane?Don't hurry.Think again.Air travel has a big impact on the environment compared with most other forms of travel.You have better choices Consider having a vacation within driving distance.Of course,taking the train is the best choice.

4.Think about how much"stuff”you own.A big part of emissions are linked to our consumption.To reduce it we need a change in consumption culture.Do we really need all the things we buy?And do we always need the newest one?Getting fewer things and making the ones you own last longer will reduce energy use.

5.Your choices about heating and cooling your home are some of the most important things you can do in terms of cutting your greenhouse gas emissions. Keeping the temperature a little lower in the winter and higher in the summer can make a big difference
