Question What's environmental ethics?
A. A realization that humans are animals that are subject to the same environmental principles as other animals
B. A philosophy that believes all humans should behave ethically
C. A philosophy that studies the moral relationship between humans and the environment and between humans and all other living things
D. A way of understanding human behavior in the sciences

C.

Explanation:

I would probably say C because ethics in general are considered a philosophy, and environmental ethics is the part of environmental philosophy that considers extending the traditional boundaries of ethics from solely including humans to including the nonhuman world. Environmental ethics is about including the rights of nonhuman animals in our ethical and moral values.

two jet streams that directly affect the formation of weather in the continental part are a polar jet and a subtropical jet. they are responsible for the transportation of weather systems, which directly affect people. the polar front is the boundary between cold air from the north pole and warmer equatorial air. both the polar jet and the subtropical jet blow from the west to the east, and follow the boundary between cold and warm air.

the strongest jet streams are polar jets, while subtropical jets are somewhat weaker.

the right answer is c. the polar jet stream is generaly stronger than the subtropical jet stream.
