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.
Can leaves be a better alternative to plastic plates that are non-biodegradable? Read on to find what lesson the character learnt in the story!

As we gear up for winter, we cannot ignore that this is the time when we experience the worst of air quality across cities and towns. The air we breathe is filled with toxic pollutants like nitrogen dioxide (NO2), sulphur dioxide (SO2), carbon monoxide (CO), particulate matter (PM 2.5, PM 10), lead (Pb), ozone (O3), among others, arising from multiple sources such as vehicles, industries and power plants.

In the guise of development, what allows us to be callous with earth's resources? A study conducted by Indian Institute of Soil Science shows that majority of the soil in India is deficient in secondary nutrients, such as sulphur, and micronutrients, such as zinc, boron, iron, copper and manganese. The question then is how nutritious can our food be if it is grown on malnourished land? Many other villages are suffering, like Jaduguda and Kolaghat, because the polluter does not take the responsibility of the waste, burdening locals with unseen consequences...
