Climate Change and Health

I interviewed one of my best friends about this issue. He is an ingeneer. Here are his responses:
1) What he things an individual can do to reduce their individual carbon footprint
a) Reduce electrical consumption overall in all related to heating and refrigerating.
b) Use public transport instead of going by car.
c) Do a correct separation of the rubbish for recycling.
2) What that person thinks he or she would really consider doing herself
a) Change windows to others that keep the temperature of the house.
b) Change light bulbs and put more efficient ones.
Personally speaking, I think, we as individuals can do a lot to reduce our carbon footprint. The majority of the mesuares wil improve our health.
