Have you ever heard of the Fisker Karma?  Not surprising if you have never heard of it as it is not a popular car.   But it is a really beautiful supercar.  It is also a hybrid car, an environmentally-friendly car.  Environmentally-friendly car should be the future.  But its manufacturer has become bankrupt (http://www.ibtimes.com/will-troubled-us-plug-electric-sports-car-maker-fisker-end-being-chinese-us-car-company-1274749).

Karma is a religious concept.  We reap what we sow.  Pollution is getting worse in big cities like Hong Kong, Beijing and other cities in China.  It is reported by the World Health Organization that severe air pollution can cause cancer (http://www.usatoday.com/story/news/world/2013/10/17/cancer-air-pollution-carcinogens/3002239/).  But why are so many polluting cars and buses still being widely used?  Why are industries still using polluting methods?  Why is coal still used for heating?  Maybe people care too much about their profit and have no regard for the environment.    Although big companies are aware they should have social responsibility, smaller companies are not as they cannot afford the cost.  Being socially responsible most often has a cost, and for these small companies, survival comes first.  In this respect, people have to be selfish.

So it is up to the consumers themselves to make these companies change.  For their own health, they must.  We should only buy from the companies that care about sustainability.  Destiny is in our hands.
