Fresh air is very important for us. We can live without food and water for some time; but not even for a few minutes without air. We cannot see air. It is a mixture of many gases.
Without air, our planet would be lifeless. Fresh air is very important for plants and animals too.
Nature provides us with fresh air through plants and trees. So plants and trees help to generate fresh air. In cities, the air gets mixed with harmful gases from factories and vehicles. This polluted air makes us fall ill.
We should plant more trees to keep the air fresh. We should not throw wastes everywhere. We should try and keep our surroundings clean. This will helps us to live a healthy life. We should protect forests from being cut down. We should all join hands to build a greener and healthier environment.
