What if there were no Trees on Earth?

A world without trees would be…….very, very bad.

There are approximately 3.04 trillion trees on Earth, covering around 31% of the land surface. Around 15 billion trees are cut every year. Hypothetically, speaking it would take nearly 200 years for the trees to disappear from the face of Earth. While this scenario is unlikely, what will be the consequences if this happens for real? An awful thought! And a very dangerous one. No more shady, leafy canopies. No more flowering magnolias or cherry blossoms. No more protection from windy rains. The world would seem naked without the most essential component required for the survival of humans.

Eighty percent of the land animals and plants reside in is the forest and the absence of trees would lead to the death of every living organism on the planet. Trees keep the ground cool and wet and ensure to drive the water cycle. A large tree can push 150 tonnes of water into the atmosphere every year, which eventually falls back in the forest as rain. With no trees, the land would dry up and the dry wood would result in an enormous wildfire. The lack of trees will fill the sky with soot that blocks the sun, causing failed harvests for several years and leading to worldwide famine.

The loss would go far beyond the aesthetic. Over time, it would be impossible for the world to go on without the generation of oxygen. Oxygen, a vital component for the survival of human beings would be hugely affected by the depletion or disappearance of trees on Earth. We rely on oxygen for preventing flooding or erosion, filtering pollutants, generating rainfall that feeds our crops, and much more. A world without trees wouldn’t be a good world for humans.

For instance, on this World Environment Day 2019 let’s all suppose what all chaos will happen if trees magically disappear.

  1. Trees intercept the raindrops which impact the ground relatively hard and allow them to fall more gently on the ground. Trees ensure rainwater harvesting by draining the water down the stem/trunk. In the absence of trees, there would be large scale erosion and flooding. Many rivers and streams would be clogged with eroded soil and most of the fish and other organisms in them would die.
  2. Animals depending on trees for habitat or food would die of hunger and so would many of their predators. Many carnivores/ scavengers would go extinct due to loss of food.
  3. Various species of plants can’t tolerate the rays of Sun at its full power,  so those that managed not to be swept away by erosion wouldn’t survive and nor would animals that depend on them for food or habitat.
  4. The supply of wooden furniture will be affected.
  5. The absence of wooden handles for tools such as knives, axes, etc.
  6. Trees absorb the harmful pollutants such as nitrogen oxides, ammonia, sulfur dioxide and ozone and filter the particulates out of the air by trapping them on their leaves and bark.
  7. Over the last few years, the average temperatures in Los Angeles have risen 6-degree Fahrenheit as the tree coverage over the region has declined giving rise to heat-absorbing roads and buildings. An alarming statistic that needs to be considered with utmost sincerity and honesty.

This should be enough reasons to fight against deforestation. Trees need our protection and we should be there for them. Even if every human being pledged to plant one sapling, we can truly make the world a better place.  This World Environment Day 2019, let’s do our bit.
