Water being pumped into Tampa Bay could cause a massive algae bloom, putting fragile manatee and fish habitats at risk

Harmful algae blooms are an increasing problem in Florida. Once nutrients are in the water to fuel them, little can be done to stop the growth, and the results can be devastating for marine life.

New research: nitrous oxide emissions 300 times more powerful than CO₂ are jeopardising Earth’s future

Agriculture is the dominant cause for the increasing N₂O concentrations. Emissions must be reduced if we hope to stabilise Earth’s climate.
