Q & A

What is carbon and how does it relate to climate change?

Carbon is an element present throughout the ecosystem, constantly moving between air, plants, animals, and the atmosphere. It's a major component of carbon dioxide (CO2), a greenhouse gas that contributes to climate change by trapping heat in the atmosphere.

How do plants and animals interact with carbon in the ecosystem?

Plants absorb carbon from the atmosphere and store it in their bodies. When animals eat plants, they consume the carbon as well. This carbon continues to move through the ecosystem as animals eat other animals, die, or excrete waste.

What happens to carbon when animals die or excrete waste?

When animals die or excrete waste, carbon is released and moves back into the ecosystem. Some of it is held in the soil temporarily before eventually returning to the atmosphere.

How does carbon behave in the oceans?

In the oceans, carbon dioxide dissolves in the water. The oceans hold the majority of Earth's carbon dioxide, where similar processes of carbon cycling take place, just like on land.

What role do fossil fuels play in the carbon cycle?

Fossil fuels like coal, oil, and gas are made of carbon from dead plants and animals that were trapped underground for millions of years. When these fuels are burned, they release ancient carbon back into the atmosphere.

How have human activities altered the carbon cycle?

Humans have disrupted the natural carbon cycle by cutting down forests that absorb carbon and by burning fossil fuels, which releases large amounts of stored carbon into the atmosphere.

What is the effect of extra carbon in the atmosphere?

The excess carbon in the atmosphere acts like a blanket around the Earth, trapping more heat from the sun. This contributes to global warming and causes climate change.

How can we reduce the amount of carbon in the atmosphere?

We can reduce carbon in the atmosphere by protecting forests, planting more trees, using less energy, and switching to renewable energy sources that do not release ancient carbon into the atmosphere.

Why is it important to leave ancient carbon underground?

Leaving ancient carbon underground prevents it from re-entering the atmosphere, where it contributes to the greenhouse effect and accelerates global warming.

What steps can individuals take to help balance the carbon cycle?

Individuals can help by reducing energy consumption, supporting reforestation efforts, using alternative energy sources, and advocating for policies that keep carbon emissions in check.

🌍 Understanding Carbon and Its Role in the Ecosystem

The paragraph introduces the concept of carbon and its significance in the ecosystem. Carbon is everywhere—floating in the atmosphere, absorbed by plants, and passed on through animals. The carbon moves between the air, plants, animals, and the soil, continuously cycling through the environment. Some carbon, from dead plants and animals, has been trapped underground for millions of years, forming coal, oil, and gas.

🌊 The Carbon Cycle in Oceans

This paragraph highlights the role of oceans in the carbon cycle. A large amount of carbon dioxide is dissolved in ocean water, and the carbon cycle operates similarly in oceans as it does on land. The carbon from dead marine plants and animals becomes trapped and moves within the ecosystem, with some of it getting stored deep underground, while the rest circulates in the atmosphere.

🏭 Human Activities and Carbon Disruption

The paragraph explains how human activities, such as deforestation and burning fossil fuels, have disrupted the natural carbon cycle. Cutting down forests removes the natural absorbers of carbon, while burning fossil fuels releases stored carbon back into the atmosphere. This increase in atmospheric carbon is causing the system to shift, leading to global climate changes.

🌡️ The Impact of Excess Carbon on Global Warming

This section describes how the excess carbon in the atmosphere acts like a blanket, trapping heat from the Sun and causing the Earth’s temperature to rise. As a result, global changes are occurring. The paragraph underscores the idea that human actions are now altering the carbon cycle in significant ways.

🌳 Steps to Rebalance the Carbon Cycle

The final paragraph suggests solutions to rebalance the carbon cycle. It emphasizes that humans can make a positive impact by stopping deforestation, planting more trees, reducing energy consumption, and shifting to alternative energy sources. By leaving ancient carbon underground, we can help restore balance to the ecosystem and reduce the effects of global warming.

Transcripts

Lately we've been hearing a lot about global warming, and words like

carbon footprint, climate shift, carbon dioxide, and climate change.

But what is carbon, and what does it have to do with climate change?

Carbon is everywhere in the ecosystem, and it is always moving.

Some of it is floating in the atmosphere, plants absorb carbon from the air, and store in their bodies.

When animals eat plants, they eat carbon, and when something bigger eats those animals,

they're having a carbon snack too, but that carbon won't stay still for long.

When an animal poops, or something dies, carbon moves around again.

Some of it is held in the soil for a while, and eventually

most of it ends up back in the atmosphere.

The same type of process happens in the oceans too,

most of the carbon dioxide gas on earth is actually dissolved in ocean water.

Some of the carbon from dead plants and animals was trapped underground and over

millions and millions of years it turned into coal, oil and gas,

and that's pretty much how the system works.

Some carbon has stayed deep underground for millions of years,

but the rest moves around the ecosystem, from the air, to plants, to animals

and back into the atmosphere, and that's the story of the carbon cycle!

...well, it was, until we came along. We've been cutting down a lot of forests

that used to absorb carbon from the atmosphere, and we've been digging up

carbon from deep underground and burning it for energy.

Doing that pumps that old carbon back into the air.

By getting rid of plants, and burning lots of fossil fuels,

we've changed the system. The amosphere is filling up with carbon

faster than plants and oceans can absorb it.

All this extra carbon in the air is like a blanket round the earth that

traps in extra heat from the Sun.

And things are changing all over the globe.

But now that we know that we are part of the system, we can do things to keep in balance.

We can stop chopping down forests, and plant trees. We can use less energy.

Even better, we can find other sources of energy, and leave the

ancient carbon underground and out of the atmosphere.
