Do you know what anniversary is April 22nd?

April 22nd is "World Earth Day". On this day, various environmental protection promotion activities will be held around the world to arouse human beings' awareness of caring for the earth and protecting their homeland. "Cherish the earth's resources and transform the development model" has been the theme of my country's Earth Day publicity activities in recent years. Cherishing the earth's resources is closely related to everyone.

Since the 1990s, all walks of life in China have held "World Earth Day" activities on April 22 every year. Every year when China commemorates "Earth Day", a theme must be determined

In 2014, cherish the earth’s resources and transform the development model—use land resources sparingly and intensively to jointly protect the natural ecological space.

1. The concept of natural resources

Land, sunlight, minerals, forests, water, water energy, etc. that exist in nature and are valuable to humans are called natural resources.

Tip: Two necessary conditions for natural resources:

1. Exist in nature

2. Of value to human beings

Discussion: Determine whether the following resources are natural resources?

In fact, there is still vast space that needs to be developed in nature. The key lies in the advancement of science and technology. For example, rare metals such as tungsten and titanium were once treated as waste rocks, but now they have become important natural resources. Although lightning is not a natural resource now, it will become a resource when technology develops to the point where it can be utilized.

2. Classification of natural resources

Resource classification

Renewable resources: resources that can be updated, regenerated, or recycled within a short period of time are called renewable resources. Such as: land, sunshine, forest, water and water energy, etc.

Non-renewable resources: The regeneration process is very slow, and the use becomes less and less. They are called non-renewable resources. Such as: coal mine, petroleum, iron ore, etc.

Classify the following natural resources and explain why:

Hot spring trees grassland tidal energy Tibetan antelope

Wind energy Marine fish Nuclear energy Natural gas Granite

Renewable resources are:

hot spring trees grass tidal energy

Tibetan antelope wind energy sea fish

Reason: can be recycled

Non-renewable resources include: nuclear energy, natural gas, and granite.

Reason: Use a little less, it cannot be regenerated in a short time
