The human body is 75% water; Blood is 80% water. "Water is the king and source of all diseases", and water quality determines physical fitness.
75% of cancers are caused by environmental pollution, and unclean drinking water is the culprit!
Drinking unclean water for a long time will lead to: hypertension, endocrine disorders, hematopoietic system diseases, coronary heart disease, arteriosclerosis, stomach diseases, diabetes, cardiovascular and cerebrovascular diseases, accelerate human aging and make the skin rough. Scale, in particular, is the chief culprit of all kinds of lithiasis. According to the data released by the World Health Organization, due to water pollution, there are:
● 35 million people suffer from cardiovascular diseases! ● 30 million people died of liver cancer and gastric cancer! 9 million people have hepatitis! ● 70 million people suffer from gallstones, kidney calculi!
Hazards of sandstorms:
One is a wind disaster, and the other is scraping the ground.
1, let's talk about the wind disaster first. Strong winds destroy buildings, blow down or pull up tree stems, tear up farmers' plastic greenhouses and farmland plastic films, and so on. In addition, April and May in northwest China are the time when cash crops such as melons, fruits, vegetables, beets and cotton emerge, cotyledons or true leaves grow, and fruit trees bloom, at this time, they are least resistant to sandstorms. Light leaves are covered with dust, which weakens photosynthesis, affects respiration and reduces crop yield; In the worst case, the seedlings will die, not to mention the mature results.
2. When strong wind acts on loose soil in arid areas, it will scrape off a layer of topsoil, which is called wind erosion. In fact, strong winds not only blow away the fine clay and organic matter in the soil, but also pile up the sand in the soil, which greatly reduces the fertility of the soil. In addition, the strong wind with sand will wear off a layer of buildings and crops, which is called abrasion and also a disaster.
3. The harm of sand is mainly sand burial. As mentioned above, in narrow pipelines, windward and uplifted terrain, due to high wind speed, the wind-blown sand hazard is mainly wind erosion, while in leeward depressions and other terrain with low wind speed, the wind-blown sand hazard is mainly sand burial.
In addition, more importantly, the loss of life. For example,1May 5, 993, 85 people were killed, 264 people were injured and 3 1 person was missing. In addition, the death loss of large livestock was 1.2 million, the crops were affected by 5.6 million mu, the total length of the lifeline canal buried by sand in arid areas was more than 2,000 kilometers, and the Lanzhou-Xinjiang railway was stopped for 3 1 hour. The total economic loss exceeded 540 million yuan.
The main hazards of garbage to human life and environment are:
First, it occupies too much land. Garbage piled up in the suburbs of the city occupies a lot of farmland. Garbage stays in nature for a long time: cigarette butts and woolen goods 1-5 years; Orange peel for 2 years; 80- 100 cans; Plastics 100-200 years; Glass 1000.
Second, pollute the air. Garbage is a complex mixture. In the process of transportation and open-air stacking, the decomposition of organic matter produces stench, which releases a lot of pollutants such as ammonia and sulfide into the atmosphere, including 100 kinds of volatile organic gases, which contain many carcinogens and teratogens. Plastic film, paper scraps and dust fly with the wind, forming "white pollution".
Third, pollute the water source. Harmful components in garbage are easily washed into underground water by rainwater, and a large number of acidic and alkaline organic pollutants will be produced during garbage stacking or pit filling, and heavy metals in garbage will be dissolved. If garbage is directly thrown into rivers, lakes or oceans, it will cause more serious pollution. Look: plastic bottles and lunch boxes floating on the surface of Qinhuai River, plastic bags and bread paper hanging on the branches. Not only causes environmental pollution. And if animals eat white garbage by mistake, it will not only harm health, but even die.
Fourth, fire hazards. Garbage contains a lot of combustible substances, which will produce methane and other combustible gases during natural stacking. In case of open fire or spontaneous combustion, it is easy to cause fire and garbage explosion accidents, causing heavy losses.
Fifth, the nest of pests. Garbage not only contains pathogenic microorganisms, but also provides food, habitat and breeding places for mice, birds and mosquitoes and flies, and is also the root of infectious diseases.
A large amount of garbage piled up together not only occupies a lot of land, but also produces some toxic and harmful substances, giving off a stench and polluting the air and water. At the same time, it breeds mosquitoes, flies, cockroaches and mice and spreads diseases, which is extremely harmful to people's health. A large amount of garbage piled up together not only occupies a lot of land, but also produces some toxic and harmful substances, giving off a stench and polluting the air and water. At the same time, it breeds mosquitoes, flies, cockroaches and mice and spreads diseases, which is extremely harmful to people's health.
At present, the amount of garbage generated in the world is soaring every year, reaching 50 billion tons, which requires more land to pile up garbage. However, it is increasingly difficult to find a special reserve where garbage can be piled up; During landfill, chemicals may leak and pollute groundwater and land; In addition, if garbage is incinerated, it may cause air pollution. In the face of excessive garbage, the most effective solution is to reduce the generation of garbage and reuse it. If we recycle useful parts of waste, such as some bottles, cartons, handbags, etc. We can transform them into beautiful and practical home accessories to beautify our life. This can not only save a lot of resources, but also minimize the amount of garbage generated, reduce the cost of garbage disposal and reduce the occupation of land resources, thus significantly improving our quality of life. .
Using aluminum cans to make aluminum products consumes 7 1% less energy and reduces 95% air pollution than using bauxite to extract aluminum. Waste glass can be recycled into glass products, which not only saves quartz sand, soda ash, feldspar powder, coal and other raw materials (resources), but also saves electricity, reducing energy consumption by about 32%, reducing air pollution by 20% and water pollution by 50%. The energy saved by recycling a glass bottle can make the light bulb light for about 4 hours.
Waste cloth: splicing, can be made into quilt cover, cushion and other daily necessities.
Old books: Reuse them until they can't be used as waste paper. Learning books can also be donated to poor areas.
Waste batteries: recycling, toxic substances should be classified and recycled. More advocate the use of environmentally friendly batteries.
Food: used as fertilizer or processed into feed.
If people know that recycling a ton of waste paper can turn into 800 kilograms of recycled paper, it is equivalent to cutting down 17 big trees; If people know that cans can be reused 100% ......
If everyone is more aware of environmental protection when throwing garbage, the comprehensive utilization rate of garbage can be effectively improved, and the whole society can be less troubled by garbage.
