Environmental protection is around us

Again to the annual six. Five World Environment Day, this is not, the mother who is an environmental worker is also promoting environmental knowledge to me.
Since June 5, 1972, the United Nations Conference on the Human Environment was held in Stockholm, Sweden, and after the adoption of the Declaration on the Human Environment, it became the World Environment Day on June 5 each year. On this day, the United Nations system and Governments carry out activities to promote and emphasize the importance of protecting and improving the human environment. This year is already the 39th Environmental Day. In fact, on the anniversary of environmental protection, there is also the International Wetland Day on February 2, which plays an important role in protecting the habitat and migration of poultry. World Water Day on March 22, World Meteorological Day on March 23, Earth Day on April 22, World No Tobacco Day on May 31, World Day on Desertification and Drought on June 17, World Population Day on July 11 , September 16 International Day for the Protection of the Ozone Layer, World Animal Day on October 4, World Food Day on October 16, and International Biodiversity Day on December 29. Ha, there are a lot of commemorative days.
Why do you have to do so much environmental protection? Mom said that when they were young, it was really blue sky and white clouds, the green trees surrounded the river, the air was sweet and the fruit was fragrant, and everything was as we go to various scenic spots. I am so envious, I live in picturesque scenery every day. In addition, my mother said that the future direction of economic development will be a "low carbon economy"! Everyone knows about carbon dioxide and photosynthesis. The concentration requirements for carbon dioxide in different crops are different. Major food crops such as wheat and rice are sensitive to carbon dioxide and may increase yield by 10-15%. However, carbon dioxide has an adverse effect on crops such as corn and sorghum. Carbon dioxide is a greenhouse gas that affects the quality of the atmosphere and warms the earth, causing floods and torrential rains.

Then how do our small students become environmental protection guards? I can have a little trick. Have you checked the school supplies, pens, pens, pencils, erasers, correction fluids, pencil cases, rulers, and so on. There is environmental protection here. I often choose a mechanical pencil or a recycled paper pencil instead of a wood pencil. Because the winning streak of developed countries has already regarded the manufacture of wood pencils as "sunset industry". The small pencils consume trees and are amazing. I also try not to use disposable pens and signature pens, try to use rubber, and do not use correction fluid. These things are basically chemical-containing plastic products that are difficult to degrade in nature.
In daily life, there are also tips. For example, I sometimes wear a small handkerchief to wipe the sweat and reduce the napkin. I also try to save food, and the grains are hard and environmentally friendly. During the spring tour, my mother gave me a delicious snack and bought less plastic packaging food. I also like to be active in the sun, riding more bicycles, and eating less chewing gum...
Come on, saving is a fashionable and civilized lifestyle. The ancients said: A porridge and a meal are hard to come by, and they are hard to find. We want to "all the things that can be made, about all the things to do".
