There is great interest in the topic of how long humanity will be able to exist on the Earth. For many years people have contemplated the apocalyptic visions of the world, with ancient civilizations such as the Mayans attempting to estimate when it would be. Nowadays however, science provides a more reasonable approach. Renowned astrophysicist Stephen Hawking and other Nasa affiliated scientists have studied such chances and risks, mentioning climate change and resource scarcity as two important ones.
Stephen Hawking sounds the alarm: Humans may not be able to replicate naturally existing Earth environments until 2600
Among the many elites exceptionally skilled in modeling the future of the Earth, Stephen Hawking stood out as a singular authority. The Search for a New Earth Dawkins documentary scandalous stated that things might take another hundred years or so before the life on earth could be sustained, probably about till the year 2600.
He even imagined a future where looking at the planet he would just see a big ball of fire. This fear was rooted in problems such as, global warming, and the perils of climate change in general, a strong greenhouse effect. He warned that there were these environmental problems that could turn the Earth into a desert in the future if not tackled. Back to the recalibration of water. His warning sounds emphatic of what got African period the said urban level it to extreme management of humans’ footprint on the Earth’s efficient level.
Is climate change something to be afraid of? Stephen Hawking’s perspective on the changes in the world
While NASA upholds some facets of Hawking’s concept, it refrains from narrowing down on any time figure. The space organization rather stresses the need for caution against the full exploitation of the resources of the earth’s crust instead, saying that the world at the present pace is likely to tear the planet apart within a very short time.
Exhausting sources such as crude oil and natural vegetation territories increases the pressure on an already vulnerable environment, causing more risk to the continuation of life on mother nature. Regarding this, flare programs have been set up by NASA aimed at reducing the threats to the environment that include observation of climate change as well as encouraging initiatives to minimize the effects of human activities. To save Earth, as understood by NASA, one must first study the Earth in much depth and trying to do that involves a lot of sciences.
NASA’s emphasis on planetary defense: Shielding the Earth from celestial threats
Besides exploring how uniform climate is waning, NASA also investigates threats coming from space. Planetary Defense Coordination office of NASA, in this case works, to save the Earth from, say asteroid hits, which are hazards among others that may cause destruction on earth.
Keeping the worrisome through supervision of these objects is what NASA intends. Alongside, NASA also spends a lot of its finances in Earth observation including changes in atmospheric factors, oceans and polar regions that contribute to global warming trends among others. These activities show how active this strategy is, as it incorporates both approaches in its efforts towards protection of the planet.
From the warnings issued by Stephen Hawking and the research carried out by the NASA, there is no time to waste and hence solution must be pursued with urgency. For instance, Hawking’s forecast tells of what may happen if nothing is done, averaging in the fact that NASA proposes what can be done to avert the calamity.
Solutions for which environmental sustainability is
called for, climate change crisis mitigated, and biodiversity preserved are all
critical in ensuring that there is life maintained on the surface of the
planet. The future of the Earth therefore lies on the ability of the people to
compromise and do the restoration of the harm that has been inflicted on the
planet. There are straightforward warnings from science and so it is either
humanity will act, or the world will be no more like it is today.
