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.
1 1. What are the common environmental pollutions? What is its origin?
Sewage, waste gas, garbage, noise and light pollution are common urban pollution.
Source:

15 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.
16, 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".
