It is not only the duty of everyone to protect environment, but each of us should commit our-self that we will follow certain steps that will help us in protecting our environment;
• We should adequately use most important resources available with us.
• We should minimize the electricity consumption by using energy saving appliances such as 4 & 5 start refrigerator, fan, AC, etc., and also we should use LED lights as these consume very less power.
• We should start using solar appliances, and if we have enough space, we can install solar panels in our rooftop.
• We should discourage use of plastic. Even many people still use plastic although it is banned in many cities and states.
• Most importantly we should grow plants, as much as we can.
You can plan your speech using the above points.
