Global CO2 emissions need to drop to net zero by 2050 to limit the temperature rise to 1.5 degree Celsius above pre-industrial levels. Since fossil fuels account for 80% of global energy consumption and 75% of greenhouse gas emissions, countries are transitioning to cleaner energy systems like renewables and promoting energy efficiency...

Wetlands purify water through natural processes where aquatic plants act as bio-filters. Plants absorb phosphates and nitrates from the water and roots help to put back oxygen into the water. Constructed wetlands are a cost-effective method of treating wastewater and polluted water bodies. These are low cost solutions and can be easily made or replicated.

Millions of years of evolution . . . replicated in an instant!
