Important Things To Know About Green Earth
Quick, what goes into your mind if you hear the word “Global Warming” or “Climate Change”? You may think of something like the world gradually turning into a deserted wasteland. Rivers and lakes gradually dry up, crop production becomes lesser, sea level rises, and the polar ice caps melt at an unprecedented rate. You may also base your way of thinking about this issue by observing the current changes in our environment. Like rapid temperature change, harsh and colder winter season and very hot and dry summer season. Frequent occurrences of extreme weather phenomena like typhoons, droughts, intense rainstorms and heat waves.
Well, your observations are totally correct, but sometimes, we experience the very opposite of our worst expectations. We see and experience something that is beyond our expectation. And see this as rather a positive effect. In a paper submitted by the Nature Climate Change, it shows that the planet is getting more lush and greener rapidly over the past 30 years. It also shows that half of the land used for farming and pretty much any land lush with vegetation is much greener than before.
A study made by an international assembly of 32 experts from 8 different countries led the effort. It used NASA’s Moderate Resolution Imaging Spectrometer and National Oceanic and Atmospheric Administration (NOAA) Advanced Very High-Resolution Radiometer’s (AVHRR) images and data to determine the leaf area index (amount of leaf cover) over all the vegetated areas of the planet. They have found out that the planet becomes more lush with vegetation and still continues today.
These experts fear that although this event is leaned on the positive side of things. They are still skeptical about it and are fearing that this event may have dire consequences in the future.
Why Does This Happen and What Are Its Effects?
There are many reasons why this happens. For one, we all know that carbon dioxide is essential to a plant’s survival. Plants process carbon dioxide from the air and energy from sunlight. Plus all the nutrients it absorbs from the ground for their growth, in return, it provides us all food, fuel, and anything we need that is plant-based. It is a proven fact that since there is an abundant amount of carbon dioxide in our atmosphere, plants will have more for their photosynthesis, which makes them greener. This is somewhat akin to what happened to the planet millions of years ago. Where plants grow so huge due to the abundance of carbon dioxide in the air.
Not just carbon dioxide, but also nitrogen from the ground (mostly the fertilizer we use). Climate change (increased global temperature, more sunlight trapped, more ingredients for photosynthesis), precipitation and changes in weather patterns all contribute to the greening effect of the planet.
The Main Reason
In short, humans and their activity are the main reason for why this happens. This rapid greening of the planet may cause a lot of negative effects than positive ones to our planet. The main impact of this is more extreme weather occurrences worldwide due to the worsening case of climate change. We may experience intense droughts, severe flooding in low-lying areas, the melting of the polar ice caps – which is the biggest freshwater reservoir of our planet. Harsh storms in areas of the world where storms seldomly occur. And bizarre weather patterns that may result to food shortages and the extinction of a lot of species of animals.
The earth turning greening has before been just one of the signs that our environment is suffering from all those years of human’s negligent actions. And abuse without thinking about the consequences of their action. Planet earth went through a million of years of extreme changes. Extinctions and events create a perfect environment for us humans, but just around a hundred years of human activity is all it needs to jeopardize the planet’s ecosystem. Let us remember that since it is our fault why this is happening, it is also our obligation to fix this and maintain the balance of our planet.
