Thank you for all those informations, Environmental Conservation is important because when we protect the environment, we are not protecting some distinct, distant entity but ourselves.
Right to Life and Right against Exploitation are Fundamental Rights of all organisms dwelling on Earth. We (all organism, us included) have the right to demand protection when threatened by any other organism.
If a terrorist threatens to disrupt social order, demand protection. If a virus threatens to infect you, demand protection (vaccination).
This right also comes with an inherent duty to protect other organisms, that we know are being exploited. If a militant extremist tries to kill a human friend demand protection. If a multinational corporation tries raze down a forest, Demand protection.
If you have understood this simple principle, then you have Understood the importance of Environmental Conservation.
We are the Environment.
