1, go out and ride a bike, kill two birds with one stone for fitness and environmental protection.

Buying less unnecessary clothes is a new fashion of environmental protection.

3. Reduce the purchase of over-packaged goods.

4. Drive less than one day a month, and save energy and fuel by consciousness.

5. Use less disposable plastic bags and save energy by green shopping.

6. Use less disposable wooden chopsticks to protect forests and reduce carbon emissions.

Any human activity may cause carbon emissions, for example, ordinary people can cause carbon emissions as long as they cook with fire, and the exhaust gas after burning any object will produce carbon emissions.

Fuel itself is an organic hydrocarbon, so if it can't react with oxygen in the air and become water and carbon dioxide which are basically harmless to human body and environment (but carbon dioxide is being considered as a greenhouse gas harmful to the global atmospheric environment), it may become harmful substances and be discharged.

For example, this is the case when the ratio of fuel to air is too small (the mixture is too lean), which is one of the main mechanisms of hydrocarbon (HC) emission.

Extended data:

Carbon emissions are not only caused by fuel combustion, but also by population growth and economic growth. The main reason for global warming is that in the past century, humans have used a lot of fossil fuels (such as coal and oil) and released a lot of greenhouse gases, such as carbon dioxide.

Because these greenhouse gases have high permeability to visible light radiated by the sun and high absorption to long-wave radiation reflected by the earth, they are often called "greenhouse effect", which leads to global warming.

The consequences of global warming will redistribute global precipitation, melt glaciers and frozen soil and raise sea level, which will not only endanger the balance of natural ecosystems, but also threaten human food supply and living environment.
