Hey there! Today, we’re diving into a super important topic: climate change. Right now, our planet is going through some big changes because of climate change, mostly caused by humans releasing too much carbon into the air. To tackle this huge problem, we need different solutions, and one of them involves trees.
Trees have been around for about 370 million years, and they’re amazing at taking carbon out of the air and storing it. Along with green plants and algae, trees do this job better and cheaper than any technology humans have invented so far. But can trees really help us solve climate change?
Let’s look at three ways trees can make a difference: planting more trees, protecting the forests we already have, and using science to make trees even better at photosynthesis.
Have you heard of TeamTrees? It’s a project started by YouTubers MrBeast and Mark Rober. They wanted to raise $20 million to plant 20 million trees by 2020, and they actually raised over $21 million! That’s awesome, but planting millions of trees alone won’t solve climate change.
To understand why, think about this: 21 million trees can capture about 4 million tons of carbon dioxide over many years. But the world releases nearly 10 billion tons of carbon every year! So, we’d need to repeat the TeamTrees project thousands of times to make a big impact.
Felix Finkbeiner, a young tree-planting advocate, suggested planting a trillion trees worldwide. This idea came to him in fourth grade after learning about climate change. He started “Plant for the Planet,” which is now known globally.
Long ago, Earth had about six trillion trees, but deforestation has cut that number in half. While we can’t bring back all six trillion trees because we need land for homes and farms, we could add another trillion trees. This wouldn’t solve climate change completely, but it could help slow it down and capture a lot of carbon emissions.
Forests are super important because they absorb about a quarter of the CO2 humans release each year. Plus, tropical forests help control weather and keep global temperatures stable. So, saving the forests we have is crucial.
Scientists are exploring synthetic biology to make photosynthesis more efficient. The enzyme RuBisCO, which helps plants capture CO2, is a bit slow. By improving this enzyme, we could boost how much carbon plants can capture.
Even though these scientific advancements might take time, trees are a great tool we have right now for capturing carbon. But it’s important to remember that even if we save all our trees and plant new ones, we still won’t capture all the carbon we emit each year.
In the end, solving climate change needs a mix of strategies. Whether it’s planting trees, using renewable energy, or coming up with new ideas, we also need to focus on cutting down greenhouse gas emissions. It’s about what we do and what we avoid doing.
Thanks for reading! Keep exploring and stay curious about our planet.
Imagine you’re part of a global initiative to plant trees. Create a simulation where you decide how many trees to plant, where to plant them, and how to care for them. Use online tools or apps to visualize the impact of your tree-planting efforts on carbon reduction. Discuss with your classmates how different strategies can make a difference.
Join a debate on the importance of protecting existing forests versus planting new ones. Research the benefits of each approach and present your arguments. Consider factors like biodiversity, carbon capture, and land use. This will help you understand the complexities of forest conservation and its role in combating climate change.
Conduct a simple experiment to observe photosynthesis in action. Use leaves, water, and sunlight to see how plants produce oxygen. Document your observations and discuss how enhancing photosynthesis could help in capturing more carbon. This hands-on activity will deepen your understanding of the science behind trees’ role in climate change.
Participate in a role-play activity where you act as different stakeholders in the climate change debate, such as scientists, environmentalists, or policymakers. Discuss and negotiate solutions to reduce carbon emissions and enhance tree planting. This will help you appreciate the diverse perspectives involved in addressing climate change.
Write a short story from the perspective of a tree. Describe its daily activities, how it captures carbon, and its interactions with the environment. Share your story with the class to highlight the vital role trees play in our ecosystem and their contribution to fighting climate change.

Hello, everyone. Today, we will discuss an important topic: climate change. The Earth is currently experiencing climate change at an unprecedented scale and pace, primarily due to human activities that release excessive amounts of carbon into the atmosphere. Addressing this significant issue will require a variety of solutions, and many are considering the role of trees in this effort.
For approximately 370 million years, trees have been a crucial mechanism for removing excess carbon from the atmosphere and storing it. Along with green plants and algae, trees capture carbon more effectively and economically than any human-made technology available today. However, the question remains: Can trees make a substantial impact in mitigating climate change?
We will explore three approaches in which trees could contribute to solving climate change: planting more trees, conserving existing forests, and utilizing advancements in synthetic biology to enhance photosynthesis in trees.
One notable initiative is TeamTrees, a project initiated by MrBeast and Mark Rober, which aimed to raise $20 million to plant 20 million trees by 2020. They successfully raised over $21 million, which is commendable. However, it is important to note that planting millions of trees alone will not resolve climate change.
To put this into perspective, the area covered by 21 million trees is smaller than one might expect. Research indicates that such a forest can capture approximately 4 million tons of carbon dioxide over several decades. Given that the world emits nearly 10 billion tons of carbon annually, we would need to replicate the TeamTrees effort thousands of times to make a significant impact.
Felix Finkbeiner, a young advocate for tree planting, proposed the idea of planting a trillion trees globally, which is the estimated number of trees we can accommodate. This concept originated when he was in fourth grade, inspired by a presentation on climate change. His initiative led to the formation of “Plant for the Planet,” which has gained international recognition.
Historically, the Earth had around six trillion trees before significant deforestation occurred, leaving us with about three trillion today. While restoring the full six trillion may not be feasible due to land use for settlements and agriculture, we could potentially recover an additional trillion trees. Although this alone will not solve the climate crisis, it could help limit global temperature rise and capture a significant portion of human-made carbon emissions.
Forests play a vital role in carbon sequestration, absorbing about a quarter of the CO2 emitted by humans each year. Additionally, tropical forests regulate weather patterns and maintain global temperatures. Therefore, preserving existing forests is crucial in combating climate change.
To illustrate the urgency, consider that the Amazon wildfires in 2019 destroyed at least a billion trees, while the Australian bushfires this year may have consumed over 10 billion trees. Protecting our current forests is often more cost-effective than planting new ones.
Furthermore, natural processes like photosynthesis currently absorb only about half of the CO2 we emit. Experts suggest that both conserving existing trees and planting new ones are essential strategies.
An emerging area of research is synthetic biology, which aims to enhance the efficiency of photosynthesis. The enzyme RuBisCO, responsible for capturing CO2 in plants, is relatively slow and inefficient. Scientists are exploring ways to improve this enzyme, potentially increasing the carbon capture capabilities of plants.
While advancements in synthetic biology may take time, trees remain a readily available solution for carbon sequestration. However, it is crucial to recognize that even with all existing trees preserved and new ones planted, we would still not absorb all the carbon emissions produced each year.
In conclusion, addressing climate change requires a multifaceted approach. Whether through tree planting, renewable energy, or other innovations, we must also focus on reducing greenhouse gas emissions. Solving climate change involves both actions we take and those we refrain from.
Thank you for your attention. Stay curious.
