The human impact on this Earth


The human impact on this Earth


 Land, water, air. Our lives depend upon them. Since humans evolved, our population has grown rapidly. We have used and abused our Earth.
 Humans have had a serious impact on the land. We use it to grow crops to feed our growing population. We also use it to provide energy. Each year one person in North America uses resources equal to over 12 acres of land!
One of the largest impacts humans have had on the earth is the mining of mineral resources. Almost everything we use is made of metals and other land resources. We use copper to make wires that carry our electricity. We use sand and gravel to pave our roads. Many of our appliances are made of aluminum and other metals.

The extraction of all these resources takes a toll on the Earth. Large amounts of soil and rock need to be moved. The landscape is completely changed. Topsoil is lost. Ecosystems are disturbed.

Farming disrupts the natural ecosystems that exist on earth. Chemicals are used to kill pests such as insects and weeds. These chemicals can harm plants and animals that are good for the environment. When fields are plowed, topsoil is lost. It can take thousands of years for it to form again.
Pollution and destruction of natural habitat has also caused much extinction. It is like we invade their land, beg for shelter and then force the original occupants (animals) out.

 Man needs to stop and realize that earth is not a part of him but he is a part of this planet! Only then can we make a difference here, a good difference…
And what do you think? can you change your thinking and you form of act with your Earth?

  1. I completely agree with you, we need to make a change if we want there to be a place to live for the next generations.

    That is a link to a footprint test that will tell you how are you living, and "how many earths" would it take to support your lifestyle. I did it and even though i was already doing some eco-friendly activities, I learned that that is not enough, maybe I won't be able to make a difference by myself, so i am asking you to make one too. great post.

  2. Wow, it is really shocking how we have destroyed the earth and continues doing it. Many people have this idea that the earth is something that belong to them, but that not true. We are blessing of have a planet with an amazing variety of animals, vegetation, etc. We are not the owners of the earth so it is our obligation to protect it and preserve it...I think that it is possible make a change, if everybody help, we can save the earth from there destruction.
