answer:The polar ice caps are melting primarily due to increasing temperatures caused by the natural phenomenon known as global warming. Global warming is caused by a combination of natural and human activities, with the burning of fossil fuels and deforestation being the main human contributors to this issue. The release of carbon dioxide and other greenhouse gases into the atmosphere traps heat, causing the Earth's temperature to steadily rise. This, in turn, causes the polar ice caps to melt, as the ice is unable to withstand the increasing temperatures. In addition, the loss of reflective ice causes more heat to be absorbed by the Earth's surface, further exacerbating the issue. Climate change is a complex issue, and while the polar ice caps are just one component of it, their melting serves as a stark reminder of the impact that human behavior is having on our planet.

answer:Here is a dance routine you can follow for "Just a Dream" by Nelly: Chorus: 1. Start by swaying side-to-side with the beat, while bringing your right hand up and down in sweeping motions, as if drawing the rhythm out of the air. 2. Now step forward with your right foot and pop your right hip, then repeat the same with your left foot and hip. 3. Cross your arms and snap your fingers, then roll your shoulders back with the beat. 4. Lastly, do a full turn on your left foot, with your arms stretched out, then come back to the center. Verses: 1. Take two steps to the right, while moving your arms up and down in fluid motions. 2. Now take two steps to the left, while circling your arms around, as if painting with them. 3. Drop to a crouched position and extend your arms forward, as if reaching for a dream, then bring them back towards you, as if grasping something. 4. Stand back up and take two hops backwards, then spin around and come back to the center. Bridge: 1. Take slow, dramatic steps forward, lifting your arms above your head and swaying to the beat. 2. Put your hands on your chest, and take a step back with each beat, tilting your head back in contemplation. 3. In the final line, do a pirouette turn, with your arms extended, then come back to the center. Repeat the choreography for each section until the song ends, and don't forget to add emotion and interpretation of the lyrics to your movements. Have fun dancing!
