use bio degradable products such as card instead of plastic
take your own bags to the supermarket
use the bus or walk instead of using a car
be energy efficient so turn things off when not in use
energy saving light bulbs
conserve water e.g take shorter showers, turn the tap off then brushing your teeth
make a compost heap for old vegetables

Well we could start off by getting two characters, maybe Joe and Jane. Jane is eating her sandwich as is Joe. Joe decides to throw his wrapper on the ground because he missed the trash can. "Joe you should pick that up, it's loitering" Jane advised. "Why it's not like it is going to hurt anyone" Joe replied. "Your wrong it hurts everyone a trashy environment can hurt everyone and everything that lives" Jane informed. "Okay I'll pick it up" Joe said. This is a small ordinary example of a dialogue regarding how citizens can help save the environment.

Iwould say you should mainly cover the areas about how it has no health issues or concerns, and also cover the cost, and benefits.
