They say that this global warming will have dreadful consequences forour environment, such as drought and flooding.Wha

5、t should governments do to help prevent global warming? Give reasons foryour suggestions.The earth s temperature is rapidly changing. As a result there has been alot of climate change such as heat waves, droughts and floods. Scientistsbelieve that this is the result of human activity, which is pollu

6、ting theEarth s atmosphere. This could become a disaster if governments do not act tohelp prevent global warming. They can act in three ways; by supporting research, by making laws and by keeping the general public informed.Firstly, governments can support research. For e_ample, they shouldencourage

7、 companies to develop vehicles that cause less pollution. They shouldalso support alternative sources of electricity from wind and water rather thanfrom oil and coal. As well, they should sponsor conferences to discuss theeffects of greenhouse gas emissions and possible solutions to the problem.Seco

8、ndly, they should make laws that limit the amount of greenhouse gasesthat companies can emit. Private companies should be rewarded for followingthese laws. They should also be punished for creating pollution.Finally, everybody is affected by global warming. Therefore, it is important that government

9、s involve individuals in the problem solving process.For e_ample they should encourage households to save as much energy aspossible by using more efficient light bulbs or less hot water. They should also encourage the public to recycle, and this should be compulsory for everyone.Another way of savin

10、g energy is by public transport systems. Governments shouldspend money on public transport to make it as easy as possible for the public tosave energy.In summary, it is clear that there are a lot of things that governments cando to prevent global warming. They should involve companies, support scien

Atmospheric co2 concentration increased there aretwo main reasons: first, the dramatic increase in population and the developmentof industrialization, human society, consumption of fossil fuels has increas

13、eddramatically, combustion produces a large amount of carbon dio_ide into theatmosphere, increase the concentration of carbon dio_ide in the atmosphere:second forest reduces the amount of carbon dio_ide absorbed by plants use, aspeed reduction in carbon dio_ide is consumed, also leading to highercon

14、centration of carbon dio_ide in the atmosphere. Greenhouse gases than carbondio_ide, such as methane, CFCS (freon), nitrogen o_ide and so on also need toincrease a different level.Although there are many uncertainties, it is clear that global warming onclimate, rainfall, and the influence of sea lev

Such as temperature height, deputy polar regions may be more suitable for human habitation, under appropriateconditions, higher co2 conc

17、entration can promote the photosynthesis, which plants have ahigher rate of carbon sequestration, lead to the increase of plant growth,namely the stimulation effect of carbon dio_ide, which is the positive impact ofglobal warming. But compared with the positive impact, the negative impact ofglobal w

18、arming on human activity will be more vast and far-reaching.氣候變暖的英文演講稿4There is little doubt that the planet is warming.

If the ice caps melt, a vast majority of our countries borders will be under water. Monum
