We are not here by random chance, look at the numbers and see the REAL ODDS calculated by REAL SCIENTISTS and you will see that it is impossible. Open your eyes and let the truth set you free.
Care to post these odds and the credentials of the scientists involved in these calculations?
The proponents of tallow-based fuel admit that raising livestock in order to burn their corpses for energy would be a very carbon-intensive way of making biofuel. Rearing cattle or pigs involves the emission of lots of greenhouse gases. But that's not the idea: rather, the thinking goes, people will raise livestock anyway in order to eat it. Thus it makes sense to use the waste products for energy.
The point is you're not raising cattle or pigs in order to make the oil you're using an otherwise wasted by-product. Take for instance an old dairy cow that has lived past their efficient milking years or fat byproducts stripped for otherwise useless butchers waste. Also I would imagine turning sick animals into usable oil would be a better alternative to just burning them.
Usually these sort of "and then they came to earth..." plotlines are cost-cutting measures (so they can shoot in "regular" locations instead of on elaborate sets).
Not sure this really matters. Red Dwarf has always been low budget, and the later series (7+8 and to a lesser extent 6) where more money was thrown at it also corresponded with a huge dip in funniness. Generally speaking the same few rooms are used on the ship or often just Starbug. Growing up in the UK you get used to low budget comedies and high budget stuff just doesn't have quite the right feel; Red Dwarf always used to be perfect, incredibly low budget and relying just on script and actors to make it enjoyable. My favourite Red Dwarf episode ever was Marooned and that's just Lister and Rimmer in a single part of Starbug for the whole episode (with a Thunderbirds style crash at the beginning).
If children aren't allowed to experience the world, then as adults they will walk blindly into it and wither.
When I first went to University (UK) the people who got into the worst scrapes (drinking too much to the point of being taken home by strangers and not remembering, having unprotected sex whilst drunk and not remembering) were usually from single-sex catholic schools who had been kept on a tight leash. Their first experience of the adult world was from the perpspective of someone who'd been sheltered from it.
To do nothing is to be nothing.
