Climate Change: The Good And The Bad

Climate change. The bringer of death. The one who creates extreme weather, floods and droughts. All these devastating things from just a few degrees of change, and its primary cause: us. All the excess pollution we emit, mainly in the form of carbon dioxide and methane, harm us and the environment in the long-term. It seems as if there is no positive side to this. But is there?

Cause

The main cause of climate change are the greenhouse gases we emit, which in turn results in the greenhouse effect, where sun rays like inside a greenhouse are trapped and so heat is trapped, which heats up the overall global environment. But this is not the only reason. There are also natural causes which gradually heat the earth although very minute. This includes volcanic eruptions which release high amounts of greenhouse gases and fluctuations in solar radiation.

Food security

Firstly, global warming aids agriculture. This is as higher temperature in the north lead to longer growing seasons and so greater productivity and so food security. This can reduce starvation and help with SDG 2. Moreover, studies prove that certain plants have a greater growth rate due to better photosynthesis in a high carbon dioxide level environment. However, other factors like water shortage and growth of invasive species must also be considered and accommodated to.

Bringer of life?

Secondly, due to shifting climate patterns, there may be bigger habitats for certain species, as they are more suited to live there rather than their previous location. This can increase the biodiversity of an area but may result in being a host of invasive species, bad for the food web in the area.

Are greenhouse gases really that bad?

Thirdly, the greenhouse effect is not as bad as it seems, to a moderate level. This is as without the greenhouse effect life as we see it would cease to exist and Earth itself would be a cold, barren planet. Without minimal heating caused due to the greenhouse effect, life cannot be sustained.

However, if the greenhouse effect is in excess, this is when it gets bad, really bad. The disasters we face now like extreme weather, forest fires, habitat loss are all caused by this excess.

Overall, climate change is deemed bad due to its vast consequences. If we do not stop emitting or reduce emitting greenhouse gases soon, this planet will be a hellscape.

Earth or Space?

Space. A beautiful concoction of stars, galaxies and nebulae. And to think we have only explored a crumble of this colossal cookie. However, exploration requires investment, large amounts of investment and this comes with an opportunity cost of reducing and mainly solving global problems. Space exploration can lead to the development of new technology as to improve efficiency and aid exploration. This technology can then be developed for common use. One such technology is the water purification system developed by NASA, used to purify water supplies in a spacecraft . These things can reduce global water sanitation issues and reduce disease spread as well. Overall, these technologies can reduce global issues and help in the long-term. Giant Impact Hypothesis Moreover, space exploration can help prove multiple different theories and hypotheses set by scientists. An example of this is the hypothesis Giant Impact hypothesis, which is widely accepted due to its proof  which laid in moon...

Is AI really going to take all our jobs?

AI otherwise known as artificial intelligence is the ability of a computational system to perform tasks associated with human intelligence like learning, reasoning, problem-solving, perception and decision-making. It is common knowledge that AI models are slowly improving, giving more accurate answers. Does this pose a threat to jobs? Safe jobs (For now) Well, not really. As of now, most jobs are secure, from business management to healthcare to sports to other creative fields.  And these will be there for quite a long time due to the physical presence required to do some jobs and the thinking of a human brain along with its emotional intelligence and creativity, which, as of now has not been achieved by AI. The risky side However, it is uncertain to say that no jobs will be replaced. It is predicted that in 2025 alone some portion of jobs like manufacturing, commerce, translators, etc, would be replaced by AI . And this is already being implemented with a 42% decrease in employme...
