how we can help to reduce global warming?

reuse papers (one sided papers are great for informal notes/ memos) reduce plastic usage and if you must use it, recycle it - use it 2-3 times before you discard. Dispose batteries, plastics, bottles and cans separately, take time to go to recycling units and dispose these in the allotted cans/ collectors, minimise use of aerosols. Don't litter when you go outdoors, dispose trash responsibly...yeah stuff like that. Its not a huge contribution but its amazing how even simple stuff like this is not followed!
