Q1.
How can we stop damaging forests, rivers, and wetlands? Think about what actions you and your community can take to protect these important places.
Answer

Start from what is doing the damage. The chapter names it: deforestation, overuse of natural resources, the spread of invasive species, unsustainable land use, and pollution. Each has a matching action.

The damageWhat a community can do
Trees cut for fuelwoodUse fuel-efficient stoves and biogas; plant a woodlot of fast-growing local trees so the natural forest is not cut
Untreated sewage and industrial waste in riversInsist that village and town waste water be treated before it reaches the river; keep solid waste out of drains
Wetlands filled in or built overKeep village ponds and tanks de-silted and in use — a pond that a village needs is a pond a village protects
Overuse of forest resources and illegal huntingSupport protected areas — national parks, wildlife sanctuaries, biosphere reserves and community conserved areas
Invasive speciesRemove them from ponds and roadsides and plant native species instead
Litter and plasticSegregate waste, refuse single-use plastic, hold clean-up days
Why it happens: most of these places are damaged not by one big act but by many small ones, so they are also repaired by many small ones. And it is worth doing: these ecosystems give us fresh air, fertile soil, food, fibres, timber, medicines and water, and they protect us in storms — benefits that are crucial for human survival and well-being.
