I would say climate change. Though the sun is getting larger, therefore Earth is getting warmer, we can reduce greenhouse gases in the atmosphere in order to reduce Earth's temperature. I selected this issue because at one point, if we do not stop increasing the heat on Earth, it will eventually be so hot we cannot grow crops or plants, leading to Earth's oxygen levels to significantly drop. A way to reduce global warming is to stop burning fossil fuels. This would be a good solution because burning fossil fuels, like other gases, will heat up Earth's atmosphere.
If hills happen to be on your question....then that should be the answer....hopefully i helped kk....have a great christmas when it comes and plzz give brainliest answer (trust me i need it)....
To figure out just where that earthquake happened, you need to look at
your seismogram and you need to know what at least two other
seismographs recorded for the same earthquake. You will also need a map
of the world, a ruler, a pencil, and a compass for drawing circles on
the map.
