COMPOSTING
     There's a lot of talk about the importance of recycling these days, but there's one kind of recycling that occurs continuously in nature. It's called composting, and it's not some mysterious process. It happens in forests everywhere when dead leaves fall to the ground and form the mulch that protects the soil. That mulch then decomposes into nutrients that enrich the soil and help other plants grow.    
 
     Anyone can harness this natural biological process to recycle organic materials such as food waste and leaves. Many people think it's too much trouble, however, because it takes time for the various insects and microorganisms, including fungi and bacteria, to break organic solid waste down into simpler substances.  But for those who are patient, the resulting dark brown, crumbly, nutritious soil is worth the wait.  

     An even better reason to try composting is that it reduces your impact on the environment. Yes, the scraps will decompose whether they go to the landfill or not, but the decomposition process is completely different.  When our waste is sent to a landfill, it is buried, and air cannot get to the organic material. As the organic material breaks down in the landfill, it releases methane gas, which is one of the  greenhouse gases that contributes to climate change. It is considered more devastating than carbon dioxide because it absorbs heat so effectively.  However, when this same waste is composted at home where it has access to oxygen, it decomposes aerobically and it hardly produces any methane, which is good for the earth’s atmosphere.
     If you'd like to try composting, don't just start throwing kitchen scraps in a pile.  Find a proper step-by-step guide.  Composting is not difficult, but if you choose the wrong location or put in the wrong ratio of green material to brown material, you'll have a smelly, slimy mess.  
 

Step 4:  Check your answers.

答えをチェックしてください。

1.  Where does composting happen naturally?

It occurs naturally in forests.

 

2.  Why do people think composting is too much trouble?

They think that because it takes a lot of time for materials to break down.

 

3.  When organic material breaks down in a landfill, what gas does it release? 

It releases methane.

 

4.  Does organic material break down aerobically or anaerobically when it is composted?

It breaks down aerobically.

 

5.  Is the ratio of green material to brown material important or not?

It is important.
