There are several measures that have already proven to have a positive effect on the environment and which, if we redoubled our efforts, could help reverse the situation. I believe that, while it is true that there is a lot of negative news about this situation, there are many positive and effective actions that can be taken to restore much of what we have lost, or are at risk of losing. As a result, a number of achievable measures can be implemented that will go a long way towards slowing, stopping and, over time, reversing some of the damage caused. Initially, and perhaps most importantly, we need to address the issue of carbon in our atmosphere. As a result, if CO2 emissions are cut or drastically reduced, this will in turn help reduce the level of greenhouse gases, meaning further global warming will decrease. (Climate Change Evidence and causes, 2013:33) This can be done in several ways. By continuing to develop new, greener technologies, cars and traffic in general will become cleaner, emitting fewer exhaust fumes and releasing less carbon into the air. This has already been done. At the recent United Nations climate change conference in Doha, some 37 countries agreed to comply with legally binding emissions reduction measures. (Figure C, 2012) We have seen the development of more efficient engines and hybrid models that use both gasoline and electricity. Purely electric vehicles are also becoming more popular, and new models powered by solar energy are coming onto the market. The industry is also looking at ways to exploit biomass and the possibility of hydrogen engines. In many cases these measures have already had notable effects on quality of life
