1, solar radiation is the basis of all life activities on the earth, and it is also the main driving force of the earth's climate and ecosystem. It not only affects the physical environment of the earth, but also plays a vital role in the survival and development of mankind.
2. Solar radiation is the basic energy source for all living things on the earth. Plants convert solar energy into chemical energy through photosynthesis, and then provide energy for the whole ecosystem. Animals get solar energy from plants or other animals through the food chain. The gas molecules in the atmosphere are moved by the energy radiated by the sun, forming wind and atmospheric circulation, which provides the foundation for the earth's climate system.
3. Solar radiation also has a far-reaching impact on human society. First of all, solar radiation has an important impact on human health. Adequate sunshine can promote the synthesis of vitamin D, thus preventing rickets, osteoporosis and other diseases. However, excessive sun exposure can also lead to skin cancer and other health problems.
4. Solar radiation has an important impact on agricultural production and food security. Proper sunshine is very important for the growth and maturity of crops. Global warming and extreme weather phenomena are also changing the distribution and intensity of solar radiation, which brings challenges to food production.
5. Solar radiation is also an important source to support all kinds of energy on the earth. Solar panels convert solar radiation into electric energy, and solar thermal utilization converts solar radiation into heat energy. The development and utilization of these new energy sources not only provide new energy choices for human beings, but also greatly reduce the dependence on fossil fuels, which is conducive to environmental protection.
Solar radiation poses a threat to human beings.
Strong solar wind and solar flare may interfere with the earth's electromagnetic field, produce geomagnetic storms, and affect modern facilities such as satellite communication and power grid. In addition, with the global climate change, the frequency and intensity of extreme weather events such as floods, droughts and heat waves may increase, which poses challenges to human survival and social development.
The influence of solar radiation on the earth and human beings is various, both positive and potential. People need to better understand and use the laws of solar radiation in order to meet the challenges brought by global climate change and provide more opportunities for the sustainable development of mankind. People need to adopt scientific methods to evaluate and manage the influence of solar radiation, and at the same time improve the public's knowledge and understanding of solar radiation, so as to achieve the goal of harmonious coexistence between man and nature.
