Humans use the Earth's natural resources for a number of purposes, including: energy and fuels for warmth. building materials for shelter. fuels for transport. Earth is the home planet, right for life. But rights, a notable political category, is, unfortunately, a biologically awkward word. Humans, nonetheless, have rights to a natural environment with integrity. Humans have responsibilities to respect values in fauna and flora. Appropriate survival units include species populations and ecosystems. Increasingly the ultimate survival unit isgloba l; and humans have a responsibility to the planet Earth.

Hello! Polar climate is in North & South Poles, where the weather there is extremely cold. Just by looking at the answer choices alone, A and B are both eliminated, because it is not hot, warm, or humid. Plus, the weather described in those answer choices does not fit at all. D is out as well, because the weather does not vary in the poles. It is very cold year-round. The only answer choice that even makes sense in this problem is C. Therefore, the answer is C.
