We already referenced how nanotechnology could be used to assist in cleaning up the environment. Yet you should also be aware that our current renewable resources will likely be used more effectively due to nanotechnology. This is, ultimately good, which one shouldn’t complain about. However, by creating more powerful forms of renewable resources or extraction, nanotech could actually do more harm to the environment if it is not controlled properly. Heck, our current renewables like solar energy can be quite effective. Just imagine, however, if this became too powerful. We’d potentially get radiation poisoning ourselves and our environment could be horribly impacted. Therefore, nanotech could be great for renewables but also very harmful too.
