Impact of CO2 on Environment

The video explains climate change, focusing on how fossil fuels formed millions of years ago are extracted and used by humans, leading to increased CO2 emissions and global warming. It highlights the role of trees in absorbing CO2 and the challenges they face in offsetting human emissions. The video concludes with a look at scientific tools used to study CO2 movement between Earth's surface and the atmosphere.

What is the primary focus of environmental science as introduced in the video?

• Understanding climate change and human impact

• Studying the history of dinosaurs

• Exploring the depths of the ocean

• Analyzing the structure of atoms

How were fossil fuels like coal, oil, and natural gas formed?

• Through volcanic eruptions

• From ancient swamps under heat and pressure

• By the collision of tectonic plates

• From the evaporation of oceans

What is a significant consequence of burning fossil fuels?

• Decreased oxygen levels

• Increased CO2 levels in the atmosphere

• Formation of new landmasses

• Reduction in global temperatures

What is the main problem caused by rising CO2 levels?

• Increased volcanic activity

• Global cooling

• Decreased plant growth

• Rapid climate change

What is a greenhouse gas and its effect on the planet?

• A gas that causes acid rain

• A gas that depletes the ozone layer

• A gas that traps heat, warming the planet

• A gas that cools the planet

Why is human breath not a major contributor to atmospheric CO2 levels?

• Humans do not exhale CO2

• Human breath contains negligible CO2 compared to fossil fuels

• Human breath is absorbed by oceans

• Human breath is converted into oxygen by plants

What role do trees play in the carbon cycle?

• They increase atmospheric temperatures

• They produce fossil fuels

• They absorb CO2 and release oxygen

• They exhale CO2 into the atmosphere

What is the limitation of trees in combating CO2 levels?

• They can absorb all CO2 produced by humans

• They release more CO2 than they absorb

• They can only absorb a fraction of human-produced CO2

• They do not interact with CO2 at all

How do scientists study the movement of CO2 between the Earth's surface and the atmosphere?

• By observing animal behavior

• Using specialized tools and techniques

• By measuring ocean currents

• Through ancient fossil records

What is the primary goal of scientists studying CO2 levels?

• To increase CO2 emissions

• To find ways to reduce CO2 emissions

• To stop all plant growth

• To eliminate all fossil fuels
