"An Inconvenient Truth"

         As stated by "Assault on clean air, science", the impact of greenhouse has concentrations on earth is uncertain. It is certain, however, that the more careless we are about greenhouse gases and the environment, the larger of an impact we are likely to have in the future. "We are certain about this: the more greenhouse gasses we put into the air, the more sever the impacts will be, and the greater the risk we run of triggering disruptive, even disastrous changes in climate." (Caldeira)
     A high concentration of greenhouse gases also promises serious threats to individuals. Excess amount of greenhouse gases is predicted to cause respiratory distress and premature death, especially in cities. The  rise in temperature will in addition cause an increase in the amount and severity of floods and droughts. Lives and the environment are not only at stake. Every time a natural catastrophes occurs, expenses have to be made in order to clean up the disasters. If more disasters take place, the US, and other economies, will be hurt. Therefore, it is in our best interest to help reduce the amount of greenhouse gasses in our atmosphere.
      In order for a significant change to occur in global warming, individuals, communities, and countries must take strides to help this serious issue. The Environmental Protection Agency must continue to enforce the reduction of greenhouse gasses. For example, alternative energy sources, like wind power and hydropower should continued to be used. More research on different energy sources should be made, as well as improvements on the efficiency of the already existent energy sources.
     Individuals are already making an effort to help the "Assault on clean air". For instance, already, thousands of people have invested in electric and gas powered cars. In fact, my family recently bought a hybrid car. This proves that individuals are not ignoring the issue, instead they are determined to tackle it. In the future, more efficient, fully electric cars will exist. Though we must push for a greener society, it is also important not to overwhelm society by making radical changes. Transitioning from fully powered gas cars, to half electric, half gas powered cars to finally fully electric cars is a smooth transition for society. Radical changes could cause controversy, and in addition radical changes would not give residents enough time to make the switch peacefully. Nevertheless, recycling and using greener vehicles, such as bikes, should be continued. These small tasks not only help solve the issue, but they also help bring light to the issue; which is what is needed if we to eliminate the world wide problem.
