Dirt: The Movie

This week in science class both 7A and 7B watched an amazing film called Dirt, the Movie. It really opens up your mind. This amazing film switches between many different scientists and Nobel Peace Prize winners to talk to you about dirt. Dirt is one of the bases of life. Without it we would have nothing for trees to grow in so we would have no oxygen. Without dirt we would have no plants or meat because plants need soil to grow and animals need plants to live. This film explained to me how dirt is an amazing insulator for keeping your house cool in the summer and warm in the winter, whereas concrete is cold in the winter and warm in the summer and its also a lot more expensive. One part of this film also talked about pesticides and how when farmers put pesticides on their crops it doesn't just get soaked up by the plants but it also seeps through the soil (killing everything in its way) and seeps through into the rivers and eventually into the oceans killing hundreds of fish that get washed up the next day. 

Dirt is also the home of millions of micro-organisms that this film portrayed as cute little brown squidgy things. These micro-organisms are so small you can't even see them but they help keep the soil clean and fertile. We can help the environment by making soil from dried leaves, grass, twigs, orange peel and even paper. Some scientist even made clean and fertile soil from fish entrails in only six months. I think I learnt a lot from this film and I will definitely try and make some of these things happen. If any of my readers want to watch this film you can watch it here.
