A private American rganisatin called Ppulatin Actin Internatinal (PAI) did the new study. It says mre than three hundred and thirty-five millin peple lack enugh water nw. The peple live in twenty-eight cuntries. Mst f the cuntries are in Africa r the Middle East.
PAI researcher Rbert Engelman says by the year 2025, abut three thusand millin peple are shrt f water. Eighteen mre cuntries are expected t have serius water prblems. The demand fr water keeps increasing. Yet the amunt f water n the earth stays the same.
Mr Engelman says the ppulatin in cuntries that lack water is grwing faster than in ther parts f the wrld. He says ppulatin grwth in these cuntries will cntinue t increase.
The reprt says lack f water in the future may result in several prblems. It may increase health prblems. Lack f water ften means drinking water is nt safe. Mr Engelman says there are prblems all ver the wrld because f diseases like chlera that are carried in water.
Lack f water may als lead t mre internatinal cnflicts. Cuntries may have t fight fr water in the future. Sme cuntries nw get sixty percent f their fresh water frm ther cuntries. This is true f Egypt, the Netherlands, Cambdia, Syria, Sudan and Iraq. And the reprt says lack f water wuld affect the ability t imprve their ecnmies. This is because new industries ften need large amunts f water when they are beginning.
The Ppulatin Actin Internatinal study gives several slutins t the water prblem. One way, it says, is t find ways t use water fr mre than ne purpse. Anther way is t teach peple t be careful nt t waste water. A third way is t use less water f agriculture.
The reprt als says lng-term slutins t the water prblem must include cntrls n ppulatin grwth. It says cuntries cannt prvide clean water unless they slw ppulatin grwth by limiting the number f children peple have.

Research shws that abut thirty percent f the wrld ’s peple may suffer frm the shrtage f water by 2025. Nw ver 335 millin peple in 28 cuntries lack enugh water. (要点1) It is expected that 18 mre cuntries will lack water in the years t cme, while the amunt f water remains the same and the ppulatin is grwing faster. (要点2) The shrtage f water will cause health prblems and internatinal cnflicts. (要点3) But frtunately, ways are fund t settle the prblem. (要点4)
