Three small things we can do to help fight climate change

Helping to fight climate change starts with very small actions. It doesn’t require big or complicated steps—small changes in our daily lives can make a big difference. Simple efforts in everyday life can greatly help slow down climate change. Let’s all join together and fight against climate change!


  1. Turn off lights and electronics when not in use



    Turning off lights and electronics when not in use is a very simple action, but it is one of the most important ways to fight climate change. This is because turning off lights and electronics definitely reduces overall energy consumption, which in turn reduces the amount of fossil fuels used to generate electricity.


    Most of the electricity we use is still produced by burning fossil fuels such as coal, oil, and natural gas. This means that the less electricity we use, the less fuel power plants burn, which leads to a reduction in the amount of carbon dioxide (CO₂) and other greenhouse gases released into the atmosphere. Carbon dioxide is a major gas that causes climate change because it traps heat in the Earth’s atmosphere, making it one of the biggest causes of climate change. Therefore, reducing CO₂ emissions is very important.


    Turning off lights and electronics may seem like a very small and insignificant action, but it is one of the easiest everyday habits to reduce our carbon footprint and protect the planet. Let’s all make an effort to turn off lights and electronics when they are not in use.


  2. Reduce food waste by planning meals and using leftovers


    Did you know Food waste is a major global problem with serious environmental impacts?


    Here's how bad it really is:

    • One-third of all food produced in the world is wasted—that's about 1.3 billion tons every year.

    • If food waste were a country, it would be the third-largest emitter of greenhouse gases

    • Rotting food in landfills releases methane, a greenhouse gas that is 25 times more powerful than CO₂ at trapping heat.


    Food waste is not just throwing food away—it's throwing away energy, money, and a chance to reduce pollution. Planning meals and using leftovers means you’re using only what you need, wasting less, and reducing the harmful emissions that contribute to climate change.



  3. Use reusable bags, bottles, and containers



    We all have reusable bags, bottles, and containers at home, but we often don't use them because we forget to bring them or think they're inconvenient. However, using reusable bags, bottles, and containers effectively helps fight climate change by reducing the production and waste of single-use plastics, which have a large carbon footprint.


    Making plastic bags, bottles, and containers requires fossil fuels like oil and gas.

    The more we reuse, the less demand there is for producing new plastic—which means less carbon dioxide released into the atmosphere.


    Additionally, Single-use plastics often end up in landfills or the ocean.

    When plastic waste breaks down, it releases greenhouse gases like methane and ethylene, contributing to global warming.


    Using reusable bags, bottles, and containers is a small, easy change in your routine, but if many people do it, the impact adds up. It's one of the easiest yet most important actions we can take.


As such, helping the Earth fight climate change doesn’t have to be hard or complicated. It starts with us and with the choices we make in our daily lives. Let’s be mindful of our actions—our small efforts can lead to big change.
