Information on Green Olympics, Everyone Participates in Environmental Protection .

Not littering can protect the environment, replacing coal with natural gas can protect the air, and reducing sulfur dioxide emissions are all environmentally sound practices

So the answer is: don't litter and use natural gas instead of coal

Three major themes: Green Olympics, Science and Technology Olympics, and Humanistic Olympics.

Green Olympics –

Environmental protection is the primary condition for the planning and construction of Olympic facilities, and strict ecological and environmental standards and systematic guarantee systems have been formulated.

Widely adopt environmental protection technologies and means to promote environmental governance on a large scale and in all directions

urban and rural greening and beautification and environmental protection industry development;

Enhance the environmental awareness of the whole society, encourage the public to consciously choose green consumption, actively participate in various activities to improve the ecological environment, greatly improve the environmental quality of the capital, and build a livable city.

Specific examples: five major greening projects"Basically completed, the new landscape of the Olympics is dressed up in Qingdao (search keywords on the Internet) and there is a specific case of Beijing:

In 2001, when the Beijing Olympic Games were bidding, the concept of "Green Olympics" was proposed, and the Olympic style led China's environmental protection trend.

In the past few years, the concept of "Green Olympics" has been deeply rooted in the hearts of the people, and environmental protection has become the fashion of contemporary Beijingers.

Environmental protection work has been widely supported by the Beijing Municipal People, "no car day" activities, the extensive use of reclaimed water, and the adoption of various energy conservation and emission reduction measures.

After bidding for the Olympic Games, Beijing has achieved outstanding results in environmental protection work.

Beijing's environmental protection efforts are supported by neighboring provinces and cities.

In order to cooperate with the Olympic Games, five surrounding provinces and autonomous regions have signed agreements with Beijing to jointly protect the environment.

Environmental protection work has been increasingly valued by the state.

In fact, there are many examples, which shows the degree of attention paid by the whole people

My dad's cement factory was demolished, and he said it was polluting the environment.

1) The solar cell converts solar energy into electrical energy, and charges the battery under the light pole to convert the electrical energy into chemical energy and store it for night street lighting;

2) Because the volume of 40 drops of water is 10ml, the volume of one drop of water is: v=10ml

The volume of wasted water in 12s is 10ml, and the volume of wasted water in 1s is: v1 10ml

ml, then the volume of water wasted in a day and night is: v total. v1

ml×24×3600=72000ml=72l

3) Since all objects have inertia, no matter which item, there is inertia;

When the boat is advancing, the water is pulled backwards, and the force of the water is given backwards, and the water will give the oars a forward force, indicating that the action of the force is mutual;

When a basketball player smashes the ball, the player gives a force to the ball to change the direction of motion of the ball, so the force can change the motion state of the object;

In pole vaulting in athletics, the shape of the pole changes under the action of force, so the force can change the shape of the object

4) On the side where the direction of rotation is the same as the direction of the ball, the velocity of the air relative to the ball is smaller than that of the other side, and the velocity of the two sides of the ball is different, so the pressure difference between the two sides is different, and the inherent pressure difference is generated, so the ball will rotate forward

So the answer is: (1) electricity;

3) Force can change the shape of an object, the action of force is mutual, force can change the state of motion of an object, elastic potential energy is converted into gravitational potential energy and kinetic energy, a boat on the water is subject to buoyancy, etc.;

4) Small

At present, the items included in the national air pollution index are tentatively as: sulfur dioxide, carbon monoxide, nitrogen dioxide, inhalable particulate matter, etc

Therefore, a
