How To Reduce Carbon Dioxide In The Air

The video discusses the increase in atmospheric carbon dioxide due to fossil fuel use, leading to climate change. It explores two methods to reduce carbon dioxide: enhancing plant growth and carbon capture. Plants capture carbon dioxide through photosynthesis, but the carbon is often recycled back into the atmosphere. Iron fertilization in oceans can boost algae growth, capturing carbon, but half of it is recycled. Carbon capture involves storing carbon dioxide in old gas wells, but challenges include separating it from other exhaust gases. Solutions focus on capturing carbon from large engines and considering energy costs.
