3.3.1 Life & Conditions 2

    In modern times we humans face changing conditions. 

    For humans to live, we need clean air and clean water. 

    Pollution is now a growing problem around the world. 

    Pollution poisons the air and water that we depend on. 

    Polluted air makes people sick and afraid to go outside. 

    Polluted water poisons our food supply

    As a result, we never know which foods are safe to eat. 

    Human beings cannot live in a poisoned environment. 

    Therefore, pollution is a major threat to our existence.


    Humans need temperature to be in a comfortable range

    To be in a comfortable range means to be neither too hot nor too cold. 

    With global warming, global temperatures are rising. 

    As temperatures rise, the polar icecaps will melt

    As the polar icecaps melt, ocean levels will rise.

    Areas of some countries will soon be under water. 

    People will be forced to relocate from flooded areas.


    In nature, even small changes can sometimes have large effects. 

    It’s difficult to predict what’s going to happen. 

    The entire ecosystem that we depend on is changing. 

    Some of these changes are irreversible

    Irreversible changes cannot be undone


    Let’s hope that humans are smart enough to understand how the world is changing. 

    With more understanding, we can make better choices about what to do.

    We can face the challenges of the pollution and global warming. 

    We need to do this before it’s too late. 

    This planet Earth is our only home and we need to protect it.


    Irreversible changes cannot be undone because they cannot be reversed.
