Space

Yes, it is still important for us to explore space and our solar system. As you know, Earth is now too compacted with people. There are 6,775,235,700 people currently on Earth and there will be not enough space for everyone to live in. Secondly, the amount of greenhouse gases release is much more than before due to the rising cost of living and the advance in technology. Climate model projections summarized in the 2007 IPCC report indicate that the global surface temperature is likely to rise a further 1.1 to 6.4 °C (2.0 to 11.5 °F) during the 21st century.

Thus, global warming increases which caused the iceberg to melt, thus, flooding Earth. Subsequently, many other harmful effects would surface and cause mankind to be extinct! Therefore, it is very important to explore space and solar system so as to find another planet that mankind can exist and live in, before Earth is "totally destroyed".
