How does the immune system work to prevent pathogens from causing disease in the body?
Not exactly, at least not the immune system most know.In the acquired immune system, a disease enters your body and starts making you feel ill. Your immune system can now destroy this disease because it is in you and it has sensed it. Sometimes diseases are sensed so quickly and the body is already ready for it (due to memory b-cells)that you never feel it. This often happens with the chicken poxs.However the innate immune system can completely prevent certain diseases. Your innate immune system is made up of your skin, your digestive track (primarily the stomach and its acid), and mucus membranes (like inside your nose and lungs). Those systems can block diseases and send them away before they fully enter the body (cool facts, the space in your lungs and your digestive system are not considered "inside the body" - that's right, there is basically a hole going right through your person.)
How do you prevent disease?
You can not really prevent disease in general. However:- It is possible to prevent specific diseases (eg smallpox) by implementing a worldwide program of vaccination. It is possible to build sewage systems that prevent contamination of drinking water. It is possible to teach people about personal hygiene and a healthy life style. It is possible to implement food hygiene laws. All these help to prevent diseases and improve the health of a population.
How may Industrial Revolution result in problems of pathogens?
When the Industrial Revolution started, many people from the countryside moved into cities to accept a job. This influx of people overwhelmed the sanitary systems (sewers, fresh water, etc.) of many cities, causing insanitary drinking water and sewage to contaminate fresh water supplies. This led to outbreaks of cholera (Vibrio cholerae), typhoid fever (Salmonella typhi) and other bacterial diseases.

Do solar systems help prevent global warming?
Yes, solar panels and hot water systems reduce our use of electricity, as we use the sun to generate electricity and to heat the water. Most electricity comes from burning fossil fuels (coal, oil and natural gas) and this releases carbon dioxide, a greenhouse gas causing global warming. So solar systems help prevent global warming.
What makes disease contagous?
This is the ability of the disease to get transmitted from one person to other person. So chicken pox is amongst the most communicable diseases and leprosy is amongst the least communicable diseases. Although both of them has been there with you from ages.
