A) reduce the emissions of greenhouse gases( and listing any benfit that would arise)
dont drive as much, carpool, bike to school/work, take the bus, walk, etc. also use your heating system less (wear a sweatshirt and keep the heat low), eat less meat, eat local foods (less distance to travel before they reach your house, less fuel emissions), buy less, conserve more,
B) how we could change our habits to reduce our need for paper and paper products.
read the paper online, at the market, put your food in a bag that you brought, PRINT ALL OF YOUR HW ASSIGNMENTS ON BOTH SIDES OF THE SHEET, YOU CAN USE HALF AS MANY PIECES OF PAPER IF YOU DO THIS, AND ITS REALLY FUCKING EASY,
there are so many ways to do this well man, just search it on google or other sources that are far more reliable, credible and know what they are talking about than newschoolers. do you homework for real man, dont have someone nice like me just give you the answers.
