Our Footprint on Earth
by Jeanne Sturm
Review by Shanesa
Our impact on Earth varies depending on where you live. The United States is home to 5% of the world's resources. In the mid 1700's we began replacing human workers with machines. People once relied on wind, water and wood, but now rely on energy which is powered by machines that use fossil fuels, oil and natural gas.
Greenhouse gasses are contributing to global warming. Without greenhouse gasses, temperatures on Earth would be about 90 degrees colder. The sun, wind and ocean waves can help reduce the use of fossil fuels.
Rain forests play an important role in our lives. Tropical forests covered about 20% of Earth's surface before, but today it covers about 7%. Chemicals used in gardens and on plants have a harmful effect on the environment. They pollute ground water.
Non-renewable energy is fossil fuels, coal, petroleum and natural gas. Renewable resources include energy from the sun and wind. Solar cells convert the sun's energy into electricity. Hydroelectric power, or hydropower, is energy harnessed from flowing or falling water. Biomass is organic matter made from plants and animals.
It takes 5 - 500 years for certain kinds of trash to decay. When you take a shower, you use 2 gallons of water per minute. Flushing the toilet uses about 3 gallons of water. Carbon footprints calculate the amount of carbon dioxide released into the atmosphere by your activities. Charcoal that is biochar turns out to be a great fertilizer.
I would recommend this book to all people who want to save Earth, who want to reduce pollution in the environment and who want to know more about Earth. This book is on the grade scale of 5th grade on up. Children the age of ten and older would enjoy this book.
I am so excited about this adventure. Please allow me in to share with you.

I think this book is very indefinite about what they want to put their point across when it comes to talking about the Earth.Written by Alyssa
ReplyDeleteShanesa, there are some websites out there that help you calculate your carbon footprint, I'll see if I can find one and we can do it as in class! 500 years is too long to break down trash, I'm hoping that one of you will find an efficient way to burn trash for fuel! Get working on that, will you?! Mrs. Haas
ReplyDeleteThis is an amazing book. Not only did I know that the front cover looked amazing, I found out that the book is amazing as well!

Latricia:I didnt know this much about earth until you told me and it was interesting and amazing about what you had to say about earth.Well Done!
ReplyDeleteNice job, Shanesa, very well written! All this talk about fossil fuels makes me wonder how the people of the future will power things when they run out.. Hopefully, we'll have gotten solar power working to meet our growing needs by then.
