What are businsses responsibilities toward the environment?use less energy, less hurmful tools,

There is an ethical and moral responsibility businesses
have, but it is difficult to enforce.  There is also a practical
responsibility.

Businesses, especially those that consume
resources, have an ethical and moral responsibility to use those resources and to
dispose of wastes in a way that does not harm employees or the citizens that live where
that business does.

Businesses that do not do so are
fundamentally unsustainable.  These companies need clean air, clean water, and a healthy
workforce.  The environment affects all of those
things.

From a practical standpoint, businesses will be
more profitable in the long run if they are sustainable in terms of
resources.
