My speech on composting

Benefits of Composting
In my opinion I think there are a variety of advantages to composting.
So today I will be talking about 5 advantages of composting


1st reason
Compost reduces greenhouse gases.
When organic materials go into landfills and  the organic materials don’t decay it will produce a
greenhouse gas methane. If there’s a large amount of methane gas in the atmosphere then that  
is known for global warming.

2 reason
Compost improves soil quality
As we all know composting helps regenerate poor soil as it’s encouraging the production
beneficial micro-organisms (which is mainly fungi/bacteria). As then it will break down in
organic matter to create humu.
Humus help to retain moisture, as it naturally increase nutrient content in soil.

3rd reason
Compost helps clean up contaminated soil
Composting has been shown to absorb odors and treat (VOC volatile - organic - compounds,
Like explosives, heating fuels, preservatives  pesticides and both chlorinated and
non- chlorinated
hydrocarbons in contaminated soil were removed from the compost process.

reason
Compost helps control erosion
Compost is shown to prevent erosion on embankments (hill) that are side by side
from creeks,rivers and lakes. As well as turf loss on roadsides, hillside,
playing fields and golf courses.


5th reason
Compost makes and saves money
These days composting reduces the amount of water consumed by plants. As you may know or
not know composting can reduce plant disease and pests. Minimizing the need for chemical
expensive fertilizers As a higher yield  in crops growing in composted soil.

Malo e lelei Nastazia, this speech is fantastic it's so much writing, the paragraph I like the best is the 5th reason because I agree with you because I think that It can save people's money and not buying loads of shopping. I did a speech on composting to but I never talk about the benefits of composting. Was it hard for you to write all the paragraphs?
