If the Hindu idea that every part of the natural world is taken seriously and practiced by the majority of the people, then lot of environmental problems will be solved with relatively ease. If people stuck to this idea, the animals that are endangered will start to recuperate because the poaching will stop. The ecosystems will start to slowly reestablish themselves because they will not be destroyed. The pollution of the water, soil, atmosphere will be reduced significantly which will result in much healthier conditions for life.
Unfortunately, the main excuse against something like this is that it is not economically justifiable, and the majority of the people go along with it.
