What would happen if all world trees died?

Long story short? No trees equals no humans – it’s not that complicated is it? Let’s look at it this way: imagine your lungs all of a sudden dying out on you, how long do you think you’d be able to survive without them?

The trees that have graced this planet for millions of years are nothing short of absolutely crucial to the survival of every living species residing on earth. Essentially, the world’s trees serve as this planet’s lungs, granting breathing creatures like you and I the all-important natural resource that we need for survival: oxygen.


Why do we rely on trees so much?

Besides oxygen, trees provide us with a few other important things that we need to sustain our modern civilisation. Those things include: 

  1. Trees store carbon dioxide, saving breathing creatures from the pain of suffocating on plain old air.
  2. Trees are essential to wildlife for many reasons, including stabilising soil and giving life to creatures of all kinds and sizes.  In-fact, one mature oak can be a home to over 500 different species – epic, right!?
  3. Trees are made from wood, which is one of the most used natural resources on the planet. Without it, there’s no telling how long it would take to find viable alternatives for the many things wood allows us to do such as crafting paper and erecting homes.

Trees are also crucial players in many economies around the world. Lush forests made up of thousands of trees, such as those in the Western Cape, are truly rights to behold. Because of this, many countries around the world are able to grow their economies by being more attractive tourist destinations.


Things that would happen if the world lost all its trees

It’s scary to image a doomsday scenario where all of the world’s trees die out because a mad scientist decided to test out a biological weapon in the Amazon Rain Forest. Whatever the reason may be, here are some of the things that would unfold if the world lost all of its trees:


  1. It’ll get a whole lot harder to breath. Without trees, photosynthesis wouldn’t happen as abundantly as we humans need it to happen. As smaller plants are left to carry the weight of the world’s oxygen needs, we would need to find different ways of pumping clean oxygen into the atmosphere.
  2. The planet’s climate would be affected in an unprecedented manner. Trees mediate the earth’s water cycles by acting as biological pumps: they suck water from the soil and deposit it into the atmosphere by transforming it from liquid to vapour. By doing this, forests contribute to cloud formation and precipitation.
  3. As more and more trees die out, formerly forested areas would become drier and more prone to extreme droughts. When the rain eventually does come, flooding would be disastrous and cause massive erosion that would wreak havoc on our oceans, smothering coral reefs and other marine habitats.


And that’s only the tip of the iceberg. At the end of the day, we need trees as much as they need us, a balance that is the perfect recipe for life. Why not get your hands on a couple of more trees for your backyard and give your home a little breath of fresh air? There’s no reason not to, right? Yes? Perfect!
