yeah, it won't be that hard to develop gills through evolution. only shortsighted silly trump voters believe we can not slow down to a crawl the rapid growth of climate change which all the actual federal agencies who have done studies have concluded is a very real, very close to becoming reality fact, a threat to the whole world's economy and well-being without harming our economy in any real way right now. here is one idea that will do the most good, the fastest...instead of giving huge tax cuts and subsidies to gigantically rich big oil and chemical companies to keep spewing out oil and chemicals for most energy usage, transfer it to green renewable sources, that will actually stimulate job growth and the economy, and will more quickly end the world's use of carbon energy for most of our needs. win/win.
