It is also easy to overlook the services that ecosystems provide humanity. they enrich the soil and create the very air we breathe. without these amenities, the remaining tenure of the human race would be nasty and brief. the life-sustaining matrix is built of green plants with legions of microorganisms and mostly small, obscure animals—in other words, weeds and bugs. such organisms support the world with efficiency because they are so diverse, allowing them to divide labor and swarm over every square meter of the earth’s surface. they run the world precisely as we would wish it to be run, because humanity evolved within living communities and our bodily functions are finely adjusted to the idiosyncratic environment already created. the author tries to persuade the reader to agree with his claim about the importance of ecosystems by

Illustrating the significance and role of green plants and diverse idiosyncratic organisms to support human life.

Explanation:

The author aims to exemplify the significance of the ecosystem and the assets that it provides to humans as he feels these services are often overlooked by humans. The author elaborates on the major idea by exemplifying the basis of human life consisting of green plants along with the flock of organisms and their efficient labor. He established the message that humanity emerged and responded to the pre-established idiosyncratic environment and it is they who pace the world not the humans as without them human life would be awful and concise. They provide diversity and beauty to the environment and thus, these services should be valued for.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
