“Now, when fossil fuels already cause problems, and also it’s exhausting, we begin to think: Do we have enough energy? The answer is yes, there is plenty. Actually, solar energy is plenty because every year, the Earth receives enough sunlight – ten times more than all possible energy resources existing on Earth. On an annual basis, solar energy can reach the Earth at least 15,000 times more than the energy consumed by the whole world. So there’s plenty. There are ways we can improve ourselves by using those energies with no pollution, also are efficient, and can maintain our living styles, or even improve our living styles, and at the same time improve the environment.”Recently, the outbreak of H1N1 (swine flu) is becoming serious everywhere. What is the relationship between disease and climate change?

As a result, these infectious diseases seem to have a great impact and influence on us humans.”“There’s an ecological Environment between a pathogen and its host. Changes in the ecological Environment not only affect the host but also the pathogen. […] For individuals, it’s about how to enhance your own immunity – to enhance your own immunity, your resistance against diseases. For public health as a whole, it’s about how we should change the ecological environment to cut off the routes of transmission and entry for pathogens into the human body, and then about how to eliminate infectious agents. That’s what we in the public health field need to focus on. So, next, I’m going to talk about how these infectious diseases are transmitted to humans after all. […]”
