Gợi ý đáp án

My ideal planet for humans to live on would provide a suitable amount of energy and heat for life to thrive. I suppose that we will be taller, stronger and more intelligent in our new life. The planet would have a diverse range of landscapes, which has a comfortable climate that was not too extreme, with plenty of freshwater sources and a variety of plant and animal species to support a healthy ecosystem. I expect that the inhabitants will have a strong sense of community and a deep connection to the natural environment, with a shared commitment to preserving the planet for future generations. In terms of technology, humans will invent advanced infrastructure to support modern living, including reliable communication networks, efficient transportation systems, and sustainable sources of energy.
