As we have seen , the Tsunami Japan, the effect of Nuclear energy after disaster. It was impossible to control the damages. But if renewable resources are used , then such damages can be prevented.

Few Facts about solar energy:
1.Argument that sun provides power only during the day is countered by the fact that 70% of energy demand is during daytime hours. At night, traditional methods can be used to generate the electricity.
2.Pollution free, indefinitely sustainable
3.Mitigates the effects of acid rain, carbon dioxide, and other impacts of burning coal and counters risks associated with nuclear energy.
4.Energy reaching the earth is incredible. By one calculation, 30 days of sunshine striking the Earth have the energy equivalent of the total of all the planet’s fossil fuels, both used and unused!
5.The surface receives about 47% of the total solar energy that reaches the Earth. Only this amount is usable.

I started the mission to not to use plastic bags or poly bags in 2009. So per day average is 4. This is what I notice when people go to markets they do not carry anything with them like jute or cloth bags. And when they purchase even a very small thing , they ask shopkeepers for a poly bags. And this is the story of educated class in India. Think about people who are not much educated and still use poly bags. This is very sad that having known in advance what are all the disadvantages of polythene , people use it blindly. I started not to use polythene mission in 2009 with few of my friends.  So if I take an average of 4 poly bags per day then in 4 years and 2 months I saved close to 1500 poly bags.

Ways to keep the environment clean: 1. User bags made of cloth or papers. These bags decompose in the environment.    Plastic bags take hundreds of years to decompose. 2. Avoid buying cold drinks in plastic bottles, instead buy them in glass bottels as glass can be recycled. I have seen glass recycling factories in Nat Geo channel. They crusj the old glass and mould it in new shape. This can be really done. 3. Avoid buying items in plastics, e.g. even if you buy biscuits or chips , they are sold in plastic packaging. What alternative I have found is: go to bakery and get fresh biscuits , cakes, and other bakery items in paper cover. So after you finish your bakery items , no trace remains in nature. This can be really done. When we go on outings, we normally go to dams, lakes or other natural places. What we take there in food items are plastic water bottles, chips in plastic packing, other similar items in plastic. This whole waste is dumped in environment. Is it really good,...
