India at 75 | Timeline: Environment



There have been innumerable hurdles, but the battle remains spirited.


Colonial era environment laws were oriented towards revenue gain or protecting upper-class interests. The first change came in 1972 when the Stockholm Conference swung the global approach towards conservation and protection. India created the administrative and legal structures that ensured forests,water and wildlife got a new lease of life. There have been innumerable hurdles since, but the battle remains spirited.
