Nitrogen makes up 78% of Earth’s air and is vital for life, but too much reactive nitrogen harms the environment. While natural nitrogen is essential for plant growth and soil fertility, excess synthetic and industrial nitrogen creates serious ecological problems. [1, 2, 3, 4, 5]

Why Nitrogen is Good for Earth

• Life Foundation: Builds proteins, DNA, and amino acids for all living things.
• Plant Growth: Acts as a core component of chlorophyll for green, leafy growth.
• Soil Fertility: Natural cycles nourish crops and natural ecosystems when balanced. [1, 2, 3, 4, 5]

Why Excess Nitrogen is Harmful

• Water Pollution: Runoff causes massive algae blooms that suffocate fish in lakes and oceans.
• Climate Change: Releases nitrous oxide, a greenhouse gas much more potent than carbon dioxide.
• Soil and Biodiversity Damage: Acidifies soils and lets fast-growing plants kill off native species. [1, 2, 3, 4, 5]
