"What does technology bring us?" Toward Civilization PPT Courseware 5

What does technology bring us?

The changes technology brings to our lives

Technology is a double-edged sword

Advocate for science and oppose superstition and cults

let us imagine

1. What would my life be like if I lived in an era before the electric light was invented?

2. If I lived in an era without television, where would I learn more about extracurricular knowledge and the outside world?

Scientific and technological achievements one: computer

Computers have brought many conveniences to our lives and work. Give examples of the benefits:

1. Online shopping

2. Experts and professors from all over the world can conduct academic exchanges without going abroad.

3. Teachers use it for teaching

4. Search various aspects of information, such as weather, news, etc.

5. Used by students for distance learning

However, computers have brought us many negative effects:

1. Computers have radiation. Long-term use of computers for study and work will cause harm to people's vision and health.

2. Building a computer requires hundreds of chemical raw materials, many of which are harmful to the human body.

3. There are more and more electronic wastes such as used household appliances and computers. If they are simply disposed of by traditional landfill or incineration methods, the damage to the environment and soil will be immeasurable.

4. Primary and middle school students are addicted to playing computer games and do not view health information on the Internet.

5. Criminals carry out various criminal activities through the Internet.

Scientific and technological achievements two: pesticides

Why do we use large amounts of pesticides in agricultural production?

Because pesticides can be used to prevent, eliminate or control diseases, insects, weeds and other harmful organisms that harm agriculture and forestry.

Is it okay to eat vegetables and fruits that contain pesticides?

Of course not! Pesticides have certain toxicity. If pesticide residues remain on vegetables, fruits and other agricultural products and reach a certain concentration, and people eat them for a long time, the pesticides will accumulate in the body and cause poisoning.
