Physical space could also be added to the long list of things that need to be utilized carefully. With a world population of 7 billion and growing, and a planet that is 72% water, living space could very well become a scarce comodity in the future. Building smart and building with the future in mind could not only save the habitats of animals, but of humans as well.
Natural resources are not unlimited and care must be exercised in their use. Biodiversity, Fossil fuels and freshwater are three extremely valuable resources that need to be conserved with utmost sincerity to make sure we have resources for ourselves and for the future generations i.e. to continue successfully as a species in this planet.
The world’s living natural resources are under increasing threat due to human activities. Loss of habitat due to human activities and over exploitation has led several species to total extinction and several others to its verge. Conservation and protection by development of more ecological parks, limited use or nonuse of certain products would eventually safeguard biodiversity that is so crucial to our existence and well being. Biodiversity conservation helps us eventually reap higher plant production, resist or minimize environmental perturbations like drought or flood cycles and fight pest or disease cycles.
Fossil fuels were created millions of years ago, under special conditions. Human civilization has been relying upon fossil fuels heavily since last 200 years. Continuing consumption at present rate, the entire deposit of world’s fossil fuel could be exhausted in next two to five hundred years. Whether we would be able to carry the beacon of civilization thus far or beyond, depends upon our present day activities. Better the methods of conservation today, farther is the hope.
Contrary to appearances, fresh water is not really as plentiful as it seems. Ninety seven percent of the water on this planet is actually salty, unsuitable for human use. Only one percent of the water on earth is available for all of our agricultural, manufacturing, sanitation and household needs. The freshwater reserves on earth are replenished by the rain cycle, powered by the energy from Sun and therefore, not exactly predictable. So it is extremely important for us to conserve water what we have now, for future generations to thrive on.
"We stand now where two roads diverge. But unlike the roads in Robert Frost’s familiar poem, they are not equally fair. The road we have long been travelling is deceptively easy, a smooth superhighway on which we progress with great speed, but at its end lies disaster. The other fork of the road - the one less traveled by - offers ours last, our only chance to reach a destination that assures the preservation of the earth." - Rachel Carson, Silent Spring
