●
Soil is very important
for people. We use it for farming, building, art, and even for landfills. 🏡
●
Soil pollution happens
when harmful things are added to the soil, making it dirty and unsafe.

1.0 How We Use Soil (เราใช้ประโยชน์จากดินอย่างไร)
Soil is super important for our daily lives! Here are the main
ways we use it:
1.
Agriculture (เกษตรกรรม) 🌱
○
We use soil to grow
plants, vegetables, and crops for our food.
○
We plant trees in the
soil to get wood for making furniture and paper.
2.
Building (การก่อสร้าง) 🏗️
○
People build houses
and other buildings on soil.
○
Soil can be used to
make building materials like bricks and concrete.
3.
Arts and Crafts (ศิลปะและงานฝีมือ) 🎨
○
We can use soil (like
clay) to make pottery such as pots and vases.
○
It can also be used to
make beautiful sculptures.
4.
Landfills (สถานที่ฝังกลบขยะ) 🗑️
○ Landfills are areas where we put our garbage. Soil is used to cover and bury the waste.
2.0 What is Soil
Pollution? (มลพิษทางดินคืออะไร)
Soil pollution is the addition of harmful materials (สารอันตราย) to the soil. This
happens when people introduce things that cannot be broken down naturally,
making the soil dirty and unhealthy.
2.1 Causes of Soil
Pollution (สาเหตุของมลพิษทางดิน)
●
Careless Disposal of Waste:
Throwing garbage, plastic, and toxic materials anywhere instead of in a proper
bin or landfill.
●
Agriculture: Using too many
chemical fertilisers (ปุ๋ยเคมี) or insecticides (ยาฆ่าแมลง) on farms. These chemicals can stay in the soil and pollute it.
●
Mining: Mining activities can
produce large amounts of harmful waste. If this waste isn't managed correctly,
it can pollute the soil and nearby rivers.
3.0 Effects of Soil
Pollution (ผลกระทบของมลพิษทางดิน)
Polluted soil is a big problem because it affects everyone and
everything! 😟
Table 1: How Soil
Pollution Affects Living Things
|
Who/What is Affected |
The Effect (ผลกระทบ) |
|
Plants 🌿 |
The soil becomes
less fertile, so plants cannot grow well. If plants grow in polluted soil,
they absorb the harmful materials and can die. |
|
Animals 🐷 |
Animals that live on
the land can get sick or die. They might eat polluted plants or lose their
home (habitat). |
|
Humans 👨👩👧👦 |
People can get sick
with diseases like cancer or skin problems if they eat food grown in polluted
soil. Landfills can also create bad smells and attract pests like rats and
flies that carry diseases. |

described in the provided textbook pages. |

4.0 How to Prevent
Soil Pollution (วิธีป้องกันมลพิษทางดิน)
We can all be heroes and help protect our soil! Here’s how: 👍
1.
Put Garbage in Correct Places:
Always throw your rubbish in a bin. Never throw it on the ground.
2.
Follow the 3 R's:
○
Reduce (ลดการใช้): Use less stuff.
○
Reuse (ใช้ซ้ำ): Use things over and
over again.
○
Recycle (รีไซเคิล): Turn old things like
paper and plastic into new things.
3.
Pick Up Rubbish: If you see litter on
the ground, pick it up and put it in a bin to help keep our environment clean.
4.
Use Compost (ใช้ปุ๋ยหมัก): Compost is a natural
fertiliser made from decaying plants. It’s a great, nutrient-rich alternative
to chemical fertilisers and helps keep soil healthy!
