When talking about conserving the environment, there are many ways where we can do it, be it individual or group. However, it must come down to effectiveness in conserving.

Individual may be easier to handle, where it starts out from your home, then it will spread slowly. The impact made would be minimal. Also there is bound to be break down in the 'spreading' of conservation as our modern society are more liberal and active in their views. Time is also a factor in determining effectiveness. What is the use when individual efforts will take 100 years to solve climate change when the effect will be felt in 50 years time, or faster?

By conserving as a group, the effects felt would be much greater. In fact the bigger the group, the more impact felt, it is more effective in conserving. With more people conserving, time taken to solve global problem is faster. People also tend to 'follow the crowd' as big organizations represents unity, where most people are attracted to.

Therefore based on effectiveness, group effort is much better than individual. Just imagine, a community planting trees to fight pollution and climate change as compared to you trying to keep your wilting plant at home alive.
