Reducing Air Pollution
by Jen Green
Review by Na'Daisa
The air in Earth's atmosphere is vital to living things. Nature can produce some pollution, but people and their machines also cause much of the pollution that harms the air and damages the natural world.
A layer of gas called Earth's atmosphere surrounds our planet like a blanket. The main gas in the atmosphere is nitrogen. The concentration of the different atmospheric gases is uneven and stronger near Earth's surface than gas concentrations higher up.
Polluted air harms life on Earth. Most polluted air comes from vehicles such as buses, cars and airplanes. Many scientists believe that air pollution is changing our weather patterns and climate.
Natural cycles such as plants and animals, help maintain the balance of gases in the air. Plants add oxygen to the air as they make their own food in a process called photosynthesis. They absorb carbon dioxide gas, water and minerals and make sugar using sunlight.
Plants release oxygen as a waste product. Animals breathe in oxygen and breath out carbon dioxide.
I've heard that air pollution is causing our climate to heat up, which can only mean one thing: global warming. Carbon dioxide levels are rising, heating up the planet, and destroying Arctic habitats. We definitely have to put a stop to air pollution!

We, as humans, can prevent air pollution because we are the cause of it. Factories need to be else where. I know I WILL be reading this book soon. -Akiera
ReplyDeleteNadasia: I dont like air pollutiion. harms our lives!not good.
ReplyDeleteNa'Dasia, just looking at the cover of this book makes me sad. This book should be read with Shanesa's book, "Our Footprint on Earth" for a well-rounded look at our environment. There are many things we can do to slow down our negative impact on the Earth. <3, Mrs. Haas
