Solutions of the problem of gGlobal Warming
...e effect, which in turn is caused by carbon dioxide emissions. Petroleum and coal are major sources of carbon-dioxide emissions. What would happen if we conserved these energy sources? The volume of carbon-dioxide emissions surely would decrease. But how? In summer and winter, we use electricity to cool our houses or provide heat. Turn down the temperature in winter and turn up the temperature in summer. Do you drive? Why not use the existing public transportation? These subtle things will reduce the use of fossil fuels. In reality, we already experienced a reduction in the use of fossil fuels during the so-called gOil Crisish in the early 1970s. (2) Find alternative energy resources I cannot recommend nuclear power as an alternative energy resource because Japanese people have experienced accidents and atomic bombs. However, there are other alternatives such as wind power, tidal power, and solar power. Many people believe that these are expensive. Why not calculate the cost of global warming into the expense of using fossil fuels? Which is cheaper? In some industrialized countries, those experimental power sources have succeeded as profitable solutions. If we impose taxes on fossil fuels that will match the expenses we are going to pay to restore our planet, people will be eager to change their use of fossil fuels to new alternative energy resources. (3) Recycle usable resources When I lived in Japan, we did not collect bottles, cans and newspapers for the purpose of recycling. However I saw people collecting them in the U.S. Why not do the same thing in Japan or other industrialized nations? In some states of the U.S., people pay five-cent deposit when they buy beer and other beverages. In order to get the money back, people collect cans and bottles. Human beings are egoistic: we have to give ourselves some kind of monetary incentive. And it works. (4) Planting ...
