"Beautify Your Home" Make Your Home Better PPT Courseware 3

Preface: We all want to live in a clean and tidy environment, and we don’t like to live in an environment full of garbage. In fact, garbage also has its own home. How can we let the garbage return to our homes and make our homes clean and beautiful?

Four categories of domestic waste:

1. Materials (recyclable, such as plastic, glass, metal, etc.)

2. Kitchen waste (can be used, landfilled or composted)

3. Not recyclable (dregs, etc.)

4. Dangerous goods (batteries, medicines, etc.)

Why recycle batteries?

A single AA battery rotted in the soil can make 1 square meter of soil permanently lose its use value; a button battery (flat shape) can make 600 tons of water undrinkable, which is equivalent to a person's lifetime drinking water.

If used batteries are mixed with domestic garbage and landfilled together, the leaked mercury and heavy metal substances will penetrate into the soil, contaminate groundwater, and then enter fish and crops, indirectly threatening human health.

Three of the five substances that pose the greatest threat to the natural environment are contained in batteries: mercury, lead, and cadmium.

Mercury is a highly toxic heavy metal that is very destructive to the human central nervous system;

Cadmium can easily cause chronic poisoning in the human body. The main symptoms are emphysema, kidney damage, liver disease, osteoporosis, and anemia, which may paralyze the body;

Lead is the most difficult to excrete after entering the human body. It will interfere with the blood system, nervous system, kidneys, digestive system and circulatory system and is highly harmful.

In order to reduce the harm of waste batteries to the environment and our own health, please recycle the waste batteries at home and put them into the nearest large or chain supermarkets, supermarkets, mass merchandisers, drug stores, etc. Recycle bin, or ask your children to take it to school for recycling. Small actions will bring us the greatest happiness!

Think about it: Why does garbage need to be sorted?

Garbage classification is for:

1. Fight against garbage pollution;

2. Recycle renewable resources;

3. Reduce environmental pollution;

4.Leave the earth’s resources for future generations.

For the sake of the environment and survival, garbage should be sorted and processed as early as possible, starting from the source. Otherwise, sooner or later, we will be eaten by garbage!
