I think that in order to have a healthy environment we should draw public attention. How can we do that? If we invent some recycling -robots people, but especially children will be thrilled,. Let me tell you how it works. If a children puts into the robot s tummy a plastic bag the robot says thank you. If it puts a plastic bottle that is says thank you and gives him a candy. How many sweets do you think the robot should have? They will learn not to cut flowers, , turn off the lights when they are not needed. Use less water by taking showers instead of baths. Responsively throw out your garbage by sorting. Comporting fruit and vegetables waste reduces the amount of rubbish buried at rubbish dumps. That the cars should not go on diesel, but should use solar energy that does not pollute the air. Smoking people will be kindly asked not to smoke on the street, but only in special arranged places. To not throw garbages in water. By doing so we could have a planet that would smile at us.
