5. What is sustainable development?

It not only meets the needs of contemporary people, but also does not harm the needs of future generations.

6. What is ecological balance?

The energy and circulation of biological system are always going on. Although natural factors and human activities often bring all kinds of pollution to the ecosystem, for a period of time, producers, consumers and decomposers can maintain a relatively stable state of balance, which is ecological balance.

7. What is the food chain?

In an ecosystem, the chain relationship between various organisms connected by food relationship is called food chain.

For example, microorganism-zooplankton-fish-human is a food chain.

8. Is the earth short of water? What are the drinking water sources in Shenzhen?

80% of the diseases in the world are related to the lack of clean drinking water and basic sanitation conditions, and the water in the future will be as precious as oil. 70% of the water supply in Shenzhen comes from Dongjiang Reservoir, and Xili, Tiegang and Shiyan Reservoir are also important water sources in Shenzhen.

9. What is a red tide? What is the main cause of red tide? What is the harm of red tide?

Red tide refers to the phenomenon that some plankton in seawater suddenly reproduce for a short time, resulting in hypoxia and fish death. The main cause of red tide is the high content of organic matter in seawater, especially nitrogen and phosphorus. When red tide occurs, swimming creatures will produce neurotoxins, which will kill a large number of fish in severe cases and threaten human beings through the food chain.

10, what are the common environmental pollution? What is its origin?

Sewage, waste gas, garbage, noise and light pollution are common urban pollution.

Source:

(1) Sewage: domestic wastewater, industrial wastewater, oil pollution, toxic substances and garbage.

(2) Air: industrial waste gas, automobile exhaust, kitchen fumes, pesticides, new plastic products, freon in the refrigerator, all kinds of garbage and waterway gas.

(3) Noise: family noise, traffic noise, construction noise and social noise (hawking, firecrackers, store stereo, etc.). )

(4) Light: visible light, laser, infrared ray, ultraviolet ray, etc.

(5) Food: additives, artificial colors and pesticides.

1 1. Is there any legislation on environmental protection?

Yes,1989 65438+On February 6th, China promulgated the Environmental Protection Law.

12, Top Ten Environmental Problems in the Contemporary World?

(1) ozone layer destruction (2) climate warming

(3) The diffusion of acid rain; (4) The decrease of biodiversity.

(5) Air pollution (6) The forest has dropped sharply.

(7) Land desertification (8) Water pollution

(9) Marine pollution (10) solid waste pollution

13, Top Ten Environmental Problems in China?

(1) Air pollution is becoming more and more serious. (2) The problem of water pollution is outstanding.

(3) The phenomenon of garbage siege is widespread; (4) Noise pollution generally exceeds the standard.

(5) Soil erosion is difficult to contain; (6) Desertification is expanding.

(7) Decreased biodiversity (8) Water shortage

(9) Decrease of cultivated land resources (10) Shortage of forest resources.

14 what is the greenhouse effect?

Carbon dioxide and water vapor in the air can absorb the heat lost on the ground, but part of the heat energy is transmitted back to the ground, which plays a role in isolating the ground. This effect similar to the greenhouse effect is called the greenhouse effect.

15, what is "white pollution"?

Foam tableware, plastic bag, etc. It is difficult to degrade and differentiate, and toxic gas is produced when burning, which will destroy the soil structure when landfill. So it is called "white pollution".

16, what is "acid rain"?

Sulfur dioxide or nitrogen oxides emitted by people, and nitrogen oxides in automobile exhaust will form strong corrosive acid precipitates when they meet with water vapor. It is called "acid rain".

17, what is water eutrophication?

Eutrophication refers to the phenomenon that the dissolved oxygen content in water decreases and the water quality deteriorates due to the massive reproduction of plants, especially algae.

18. What is the function of the ozone layer? What caused the decrease?

The ozone layer can absorb most of the ultraviolet radiation from the sun and protect the life of the earth from it. Human activities lead to the reduction of ozone layer, mainly because refrigerants, sprays and deodorants will destroy the concentration of ozone in the atmosphere.

19 what is radioactive pollution?

The phenomenon that the nuclei of radioactive elements emit α, β and ν rays in the process of decay is called radioactivity. Its rays can kill organisms in living organisms and cause cancer, leukemia, bone marrow diseases and so on.

20. What is heavy metal pollution?

Metals with a specific gravity greater than 5 are called heavy metals. Heavy metals in environmental pollution mainly refer to mercury, cadmium, lead, chromium, arsenic and other toxic heavy metals, and also refer to zinc, copper, cobalt, nickel and tin with certain toxicity. The pollution it causes is called heavy metal pollution.
