a The western area is rich in mineral(矿产) and energy resources(能源) (water, coal, sun energy, and wind power). It also has large grassland, ice and snow resources waiting to be developed. It is home to many wild animals and plants, and it gives us with important medicinal resource...
Well basically the world’s ice is slowly melting‚ so that also means our glaciers are melting (shrinking). This is a problem worldwide. The oil‚ coal‚ natural gases‚ and fossil fuels we burn affect our atmosphere and increase the temperatures that melt our glaciers. If the ...
