  • Yes - we will inevitably need it

    First off, we're already changing the planet whether we want to or not. Focusing on conservation and naturalism is good, but on a planet with 7 billion people and growing, where 25% of plant species are human-grown crops, it won't be enough to halt detrimental effects. We don't even have the political will to hold carbon emissions at current levels, let along reduce them enough to halt global warming.

    Beyond that, there is always the possibility that natural disasters could ruin the environment for us. The last 10,000 years, during which time human civilization arose, has been a stable time for the planet. The last 150 years of the modern era has been particularly stable. But it hasn't always been that way. The geological record shows that harsh environmental swings occur normally, whether driven cycles in Earth's orbital variation or axial tilt, or by discrete events such as massive volcanic outbursts. Even if we can reduce humanity's impact on the planet to something negligible, eventually we will still face natural disasters with the ability to throw the environment into chaos.

    Geo-engineering is a tool we need, whether to counteract human effects or to mitigate the damage caused by natural disasters. And there are already proposals being discussed: https://en.Wikipedia.Org/wiki/Geoengineering

  • Yes, it can happen!

    It may not be something that we are capable of doing now at the level that we would like to do it, but it is not at all out of the realm of possibility. We can debate the potential positives and negatives of it, but that doesn't mean that it can't be done.

  • It Already Has!

    Scientific evidence is pretty clear that industrialization has made major changes in the earth's atmosphere. Even if our intent was not to damage the ozone layer, change the pH of the oceans, or raise the global temperature, our actions have altered the planet. Now that we know these things, industrializing nations are surely geo-engineering in that negative direction.

    Efforts to shift power generation away from CO2 generating sources and toward things like hydroelectric, solar, and wind power are geo-engineering attempts currently undertaken, as are efforts to make electric cars and even self-driving cars, which would optimize emissions and resources through speed management and road safety.

  • It Will At This Rate

    Geo-engineering is not a solution to global warming/ climate change, but is more of a life support system for the planet earth. Harmful greenhouse gases has not even came close to being reduced and the earth continues to warm up. At this rate, devastating damage may occur and the only solution then would be to alter the earth so that it can sustain life for us again
