Shall we help the earth?

Our planet has many problems and we are responsible for these.

So all of us should do something.

Here is some simple advice.

1. Get information.

Everybody in the world should have the necessary information about saving the world.

You can easily get online environmental education and learn how to help our planet.

2. Don't waste the source of life.

There are eight planets in our solar system and only one planet has life on it, the earth.

Thanks to water on earth, we can live on this planet.

But we are wasting too much water every day, so the water levels on our planet are decreasing.

Some scientists believe that if we don't take precautions, we won't have any water in 2040.

To save water, you can turn off the tap when you don't use it and start the washing machine only when it is full.

Also, you can take shorter showers and re -wear your clean clothes.

3. Save energy.

We use electricity or fossil fuels for lighting, cleaning, going somewhere, heating, etc.

We need them for everything, but using too much electricity, fossil fuels or other energy sources is very harmful to our planet.

Wasting energy causes global warming, greenhouse gases, air pollution and climate change.

Taking some simple precautions can help our planet.

You can walk, ride your bike or use public transportation.

If you can't use public transportation, you can share a car and go where you will go with your family or friends.

You can switch off the lights when you don't need them, and you can use energy -saving bulbs and LED lights.

You can also wash your clothes at a cold temperature and use sunlight when it is possible.

4. Stop using chemicals.

Pesticides, some detergents and sprays cause a lot of problems.

They damage our health, disturb the balance of nature and cause soil and air pollution.

They are poisonous.

We should prefer eco -friendly products for cleaning and beauty.

5. Stop using plastics.

How long does a human live?

80 years, 90 years, but plastics break down in 300 to 400 years.

Plastics stay on the Earth longer than we do, so we should reuse, reduce and recycle plastics.

You can find great ideas for reusing your plastic bottles.

Google reusing plastic ideas.

Also, you should reduce your plastic usage.

For example, you shouldn't buy water in plastic bottles from the school canteen.

You can take a glass bottle from your home to school and refill and use it at school all the time.

If you can't reuse plastics, don't throw them away.

You should put them in recycling bins.
