7. Mini-Hydel Plants Mountainous regions have streamsevery where. Most of such streams are
perennial. Mini-hydel plants use the energy of such streams to move small turbines which
generate electricity. Such power plants are more or less environment friendly.

8. Traditional Knowledge and Practices Traditionally, Indian people have been close to their
environment. If we look back at our agriculture system, healthcare system, housing, transport, etc
we find that all practices have been environment friendly. But in recent years, we have been
moving away from these practices. This has caused large scale damage to our environment.

During older times, we used Ayurveda, Unani, Tibetan and Folk systems for the treatments but
now we are ignoring the traditional system and we are moving towards the western system. Not
only these products were environment friendly but they are free from side effects too.

9. Biopest Control With the advent of Green Revolution, the country entered into the use of
chemical pesticides to produce more which laid the adverse impacts on soil, water bodies, milk,
meat and fishes. To meet this challenge, better methods of pest control should be brought. One
step is pesticides based on plants like neem. Even many animals also help in controlling pests
like snakes, peacocks, etc.
