(Hậu quả – Điều gì sẽ xảy ra nếu chúng ta không bảo vệ môi trường?)
English
Now let’s talk about what will happen if we do not protect our environment.
Some people think that the environment is only about trees, animals, or nature. But that’s not
true. Everything in the environment is connected to our lives. If the environment is in danger,
then so are we.
First, air pollution affects our health. In big cities, dirty air causes asthma, lung disease, and
even early death.
For instance, due to air pollution, cities like New Delhi or Mexico City often have a dangerous Air
Quality Index. People living there, especially children, suffer from breathing issues and heart
diseases.
Second, we have water pollution. Water is something we all need every day. But many rivers and
oceans are now dirty. Factories and people throw plastic, oil, and chemicals into the water. Fish
and sea animals die because they eat the plastic or swim in the dirty water. And humans can get
sick too, especially when they drink polluted water or eat fish with poison inside. This is a big
problem in many poor countries where people cannot find clean water.
Next is climate change. The Earth is getting hotter. Why? Because we cut too many trees, use
too much oil and gas, and release greenhouse gases into the air. These gases trap heat and
make the planet warmer. This causes many problems — stronger storms, longer droughts, more
floods, and big wildfires. For example, in 2023, Canada had huge wildfires. Smoke from the fires
spread to many other cities, and people could not breathe easily. It was dangerous for everyone.
Another serious consequence is loss of animals and plants. Many forests are being cut down to
build houses or farms. When trees are gone, animals lose their homes. Many animals are now
endangered or extinct. Bees, for example, are very important because they help plants grow. If
bees disappear, we will have less fruit and vegetables.
These consequences are not just future problems — they are happening now. We see them on
the news, in our cities, and in the weather. If we don’t change the way we live, things will only get
worse.
So, saving the environment is not only about helping nature. It’s about protecting human life.
It’s about our health, our food, our homes, and the future of our planet.
