This is a long post, the goal of it is to clarify what I mean, and why I think we should have hope for the future, not fear it, I hope I don't come off too annoying in this.
I am not suggesting that we use the energy itself of fossil fuels to bind carbon, I am not that silly
What I am suggesting is we use fossil fuels to manufacture things that aid plants in growing, such as plastics and refined metals and glass for solar panels, fertilizer for plants, concrete, steel, glass for green houses and hydroponics, to grow food, and glass, concrete, steel, to build multi level farmland that is encapsulated and efficient in land area use, where we can grow crops in just the nutrients and light it need, and recycle water and its nutrients so those do not run off into the rivers and oceans to cause algae blooms. Also indoor grassland for cows to graze, and methane catching air processing.
As for faring cows, grass that dies, and it does that without the cows too, releases just as much methane as the cow would, or actually a bit more, since the cow uses some of what would have become methane to make milk and meat.
I do not like that we are clear cutting forests though, that is why I want to make enhanced land of multiple levels where we can efficiently make heaps more food than we can on a flat single level ground thing.
So the idea is basically use fossil fuels to make more efficient structures to maintain human life, and to produce energy, bind carbon into life via solar energy (plants+water+CO2 = bound carbon/food, plants+animals= meat/bound carbon, meat+humans = more humans/bound carbon).
We should recycle water better than we do, but water never vanishes while on earth, it remains on earth, just not always where we want it or in usable form, we can use power/electricity to desalinate water and make salt too, that salt can be piled up somewhere or used, water can be used, power can come from solar panels that we make with help of fossil fuels to process raw materials into said solar panels. Solar energy can also be used to grow certain algae in vats to make a oil/gasoline/diesel substitute if needed to run old machines until we can replace them with new machines that use electricity, and also to get the oil for other chemicals we need.
We should also get solar satellites up into space so we can beam energy to the ground and also to harvest and refine materials in space, asteroid mining and such. Solar panels in space should be more efficient than on the ground since there is no atmosphere to deflect sunlight from them.
Also yes I am a bit radical in that I want to release all dead carbon from the earth and make it into life, it will take some engineering to do that, when it is all bound in life it is not going to be a problem anymore.
Also cows/cattle + humans moving them around + desert = grassland
I should find the video about that for this post
of course I do not agree with him about everything, but it really helps give hope, so watch the whole video:)
As for our own impact on the environment with water and energy consumption, most of us are not even a fraction of the problem, compared to much worse things going on in the world, sure we can lessen our impact some, get a heat pump that can act as AC in summer and heater in winter, rather than use other forms of heating, also insulate your home to improve the performance of that heat pump, it is much more efficient use of power to move heat from one place to another and recycle heat from all our other machines too, get more efficient freezer and refrigerator, modern ones draw a lot less power than old versions did. Make sure you have the old replaced units disposed of in a responsible way though. As for water, that is harder for us to individually fix, however it is better for the environment to get filters/reverse osmosis maybe, for tap water, than buy bottled water, as bottled water in plastic or glass bottles consume a lot of energy to make and ship, while tap water and the filters cost less, also there could be ways to upgrade homes so that water that is used for showers and dishes can be used to water the garden, and even sewage can potentially be processed into useful nutrients for plants, but one has to do that step very correctly. Those things are hard or impossible to do if one lives in a city in an apartment though.
Also if you live in a house you can get solar panels to offset some of the energy consumption, though they cost a lot of energy to make, and as said elsewhere toxic materials too, so the environmental impact of that may be sideways rather than pure good, or pure bad/evil.
Also if you eat meat, and you can afford it, guy grass fed meat from local farmers, at least then you offset your own impact quite a bit. If you eat plants, try to get them locally and in season, but don't feel high and mighty and good for eating only plants, tonnes of creatures get killed by farming too, and pesticides also really fuck with the environment, and not all green farming techniques are better, some use worse kinds of pesticides, but really it is hard for most people to know for sure, if you have land try to grow some plants yourself, if you are allowed to maybe get some chickens too, they produce fertilizer for your garden and eggs for eating, properly managed you will get a greener garden from chickens, I know not everyone can do that though.
Cities as they are currently set up are not sustainable, but I think we can build high rise farm towers, or under ground farms, as long as we have power for the led lights, and we can also build water and nutrient recycling, yes those use power, but again we should be shifting slowly to using more of the sun, and nuclear power, and use fossil fuels to get there, again fossil fuels are fine if we bind the released carbon in life, it stops doing harm then.
