Unfortunately it is political and there is money involved. Both to pockets and to taxes. We see this in California every day. People cannot, or do not, remove their personal brassiness and we are not ready to have adult conversations about it. That is just the fact and this thread is a prime example. People say denier when they have a different opinion or view. Easier to call a name than talk rationally. Even then usually you won't convince the other which gets back to personal bias.
Here is California for you. We continue to raise alarms about our water supply and future droughts yet we continue, year over year, let trillions (yes folks, that is trillion with a T) of rainfall flow into the ocean. Even though our snow pack this year is 161% as measured earlier this week we will see politicians and others spread the word to ration water, prepare for droughts, climate change impact, etc. Pretty ironic yeah? But here is where it gets better because us older folks (just using a term someone used earlier) know the history of water and California. We know we had to build reservoirs to collect the rain water back in the day. We planned or had at the time X population. Well, X population grew to Y and Z over the years and we produced more and more crops but failed to build more reservoirs to collect the water to meet the growing needs. Not only did we not build anymore we elected to not increase any of the existing damns (Shasta comes to mind being the last one denied). Math is fun, right? Population grows, grow more food, weather is cyclical, good years, bad years, everything grows but our storage does not. Not only that no projects to ferry more of the wasted runoff to Southern California or say to even Nevada where they need it in Vegas...
So many fronts on this topic. Populations grow. Third world countries need to eat. Eating takes priority over regulations. Not all countries have the same regulations. Tourism equals dollars and that will trump your reefs. Clean energy is great but take Solar the panels are not efficient. Electric cars are nice but you need to replace / dispose of the batteries and charge the car. Electricity to your home is still coming from coal, hydro, or other means. Nuclear power is the cleanest power on earth but people don't want it and the regulations are killing it. There are the fuel rods but that is still manageable but no one agrees so let us just ignore that. List goes on and on.
Here is my take and the TL;DR version. Everyone should try and do their part. We should recycle what we can. Watch our house for wasted energy sources. Use water responsibly. If home owner or small business can afford it, install solar (continue those tax breaks to owner, not company leasing). Companies that can should encourage the use of remote workers to reduce traffic. If we as a hobbyist and general population try to do these basic things than that alone will help our dear Mother Earth.
That is how I see it.
