Clean energy vs. dirty energy. Renewable energy.The biggest challenge faced by America in 2016 is that of moving our energy use away from fossil fuels in order to address climate change.There is overwhelming scientific consensus that the increase in atmospheric greenhouse gases due to use of fossil fuels is warming earth’s climate, and will result in sea level rise, loss of agricultural areas and increasingly severe weather events. The challenge is to create the political will to take aggressive action consistent with this knowledge by reducing our reliance on fossil fuels.
<span>The EPA’s Clean Power Plan, and recent Paris agreement are steps in the right direction, but aren’t sufficient to put us on a safe path. We can achieve a greater reduction of carbon emissions by creating incentives which work throughout the economy to encourage conservation and a shift to low-carbon energy. Incentives such as a tax on fossil carbon can accomplish this without damaging the economy, if carbon-tax revenues are returned to households, for example as a dividend similar to a tax refund.</span>Look for plenty of myth-busting and interesting news to come, as well as practical tips to reduce your own energy dependence. Though no single energy source is going to be the solution, positive developments toward a cleaner future are happening every single day.<span>. Waste
Also...maybe Climate Change, Waste, Water, Food, </span>Ecosystems and Endangered Species, The Science of Public Health Issues. All of these are environmental problems we face. But Ya!!!! I hope this helps!!! This is all I know about this topic!!! Good Luck! :)
