3 (Actually Safe) Ways to Fight Climate Change

The video discusses climate change and potential solutions through geoengineering. It explores seaweed farms, artificial trees, and freezing CO2 as methods to capture carbon. Each method has its challenges, such as cost and scalability, but they offer less risky alternatives to large-scale geoengineering projects.

What is one of the main reasons scientists are considering geoengineering?

• To enhance agricultural productivity

• To reduce the amount of sunlight reaching Earth

• To find a backup plan for climate change

• To increase global temperatures

Why is seaweed considered a viable option for carbon capture?

• It grows slower than land plants

• It is difficult to cultivate in oceans

• It grows much faster than land plants

• It requires a lot of space to grow

What is a major challenge of implementing large-scale seaweed farms?

• Difficulty in capturing carbon emissions efficiently

• Lack of ocean space

• High cost of seaweed seeds

• Seaweed's slow growth rate

What is a significant drawback of current direct air capture technology?

• It is too inexpensive

• It is highly efficient

• It is too costly

• It produces harmful byproducts

What is a unique feature of the CO2 freezing proposal?

• It turns CO2 into liquid

• It requires tropical climates

• It uses monoethanolamine to bind CO2

• It relies on high temperatures
