There are fewer elevators to work, and it is not bad to run up and down for fitness.
Remember to save water and electricity, and thousands of households save energy.
Don't turn off the computer first, clean the office.
Always open the doors and windows to find the wind and blow away the dirty air and sunshine.
Paper cups, wooden chopsticks and plastic bags reduce the use of pollution.
Don't throw away the hotel gutter oil, recycle it and make soap.
Planting trees absorbs carbon and discharges oxygen, and planting flowers and grass is green.
Low-carbon actions make contributions, clear water, green mountains and white clouds laugh.
Climate warming will wait and see, and the world paradise will be newly created.
