1 . As global warming becomes more and more serious, each one of us must take action to help.

Changing what you eat could easily have a significant effect because animal agriculture creates about 14% of the world's greenhouse gas emissions (排放).     1     Each kilo consumed produces 26.5 kilos of CO2 emissions, five times more than chicken or turkey. Changing to plant-based diets could reduce emissions greatly.

Nearly all transport relies on fossil fuels. In the US, driving one mile in an average 2016 car emits 404 grams of CO2 equivalents per mile. But taking nearly any other means of transport will reduce CO2 emissions.     2    

    3     But a few quick changes can make a difference. Switch from incandescent (白炽灯) lights to LEDs. They use a quarter of the energy and last 25 times longer. And taking for showers, the average water heater is set to 140 degrees Fahrenheit. But bringing it down by 20 degrees can save 250 kilograms of CO2.

Think before you buy. The fashion industry creates about 10% of global greenhouse emissions and consumes more energy than flight and shipping combined.     4     If you' re buying food, bring your own containers and just get the amount you need.

Plant a garden instead of building a yard out of cement (水泥), the production of which creates 8% of global CO2 emissions a year.     5    

So from a burger to a cyclist, no one thing will have a big influence, but lots of little things can.
