The raw materials of plastics mainly come from non-renewable mineral energy such as coal, oil and natural gas. Saving plastic bags means saving the earth's energy. The amount of plastic waste in China exceeds one million tons every year. Disposable plastic bags not only cause huge waste of resources, but also increase the amount of garbage sharply.
Buy local products
Buying local products can reduce the carbon dioxide produced during product transportation. For example, according to a report released by the Ministry of Environment, Food and Rural Affairs, in Britain, 8% of the carbon dioxide emitted by cars comes from vehicles carrying non-local products.
Buy seasonal products
Buying seasonal fruits and vegetables can reduce crop growth in the greenhouse. Many greenhouses consume a lot of energy to grow non-seasonal products.
Local food is most suitable for local people. Other goods produced locally are easy to maintain and have low cost. Seasonal food is the most suitable mature food for species growth in natural ecology, with the most nutrition and few kinds of additives. Out-of-season food is not only expensive but also less nutritious, and the added pesticides, fertilizers and combustion improvers are also harmful to health.
4. Reduce the purchase of animal foods such as meat, eggs and milk.
Raising livestock consumes more than 2/3 of cultivated land; Animal husbandry accounts for 16% of man-made methane on the earth. The production, packaging, transportation and cooking of meat consume much more energy than plant food, and plant food accounts for 25% of human behaviors that cause global greenhouse effect.
5. Use less disposable products
Shopping malls are full of disposable items: disposable tableware, disposable toothbrushes, disposable signature pens ... disposable items bring temporary convenience to people, but bring disasters to the ecological environment. They accelerate the depletion of the earth's resources, and produce a large amount of garbage that causes environmental pollution. Taking disposable chopsticks as an example, China exports about 6.5438+0.5 million cubic meters to Japan and South Korea every year, which consumes 2 million square meters of forest resources.
6. Don't fall into the trap of luxury goods
The more fashionable the product, the faster it will be updated. Whether it's electronic products or fashion clothes, businesses are constantly innovating to stimulate people's desire to buy. Those "moonlight clan", "car slave" and "card slave" who pursue luxury consumption not only waste resources, but also bear heavy economic shackles. Whether they are rich or negative can only be known whether they are cold or warm.
7. Overpackaging
Pay attention to buying products with simple packaging. This means less energy consumption in the production process of packaging. Reduce the garbage sent to the landfill and reduce the economic burden of consumers.
8. Benefits of using recycled materials
Products made of recycled materials usually consume less energy than products made of original materials. For example, using recycled steel for production consumes 75% less energy than using new steel.
In a word, there are other ways to save energy, which need us to draw inferences from others and implement them in all aspects of life.
Global warming has sounded the alarm for us, and the earth is facing great challenges. Protecting the earth means protecting our home. Let's take action, throw away the bad habit of selfishness, save the fate of the earth's homeland with selfless kindness and kindness, and safeguard the future in which mankind can continue to survive.
