The environment, and how it benefits people, can be justified from four major perspectives. Match these justifications with the appropriate definition: A. The belief that various aspects of the environment have a right to exist and that it is our moral obligation to allow them to continue or help them persist. B. Protecting species that are beneficial to others and acknowledging the many ecosystem services we derive from healthy ecosystems. C. Acknowledges that many people enjoy the outdoors and do not want to live in a world without wilderness. D. Protection of the environment because doing so provides a direct economic benefit to people.

The correct answer is option "D'"

Explanation: The environment benefits us in many ways, it is the environment that gives us the air we breath in, and sends our emitted carbondioxide CO2 to plants and makes it available for plant to use, when plant converts the Co2 they get oxygen and energy which they use to grow food for us to eat. It is this same plant that emits the oxygen and makes it abundantly available for living things to breathe in a process called photosynthesis.

Taking care and protecting our environment will provide economic benefits to people. A congested and polluted environment is harmful to the economy and the people living in it at large.
