Looks beautiful and it is nice of you to think also about future that might not look so beautiful due to environmental issues we Earthlings have and humans cause... Not to spoil your blog or anything, but I would like to add that probably single and relatively simple thing everybody can do to help reduce global warming and it is not so commonly known. It is becoming vegan or at least eating significantly less meat and dairy products... It would contribute much more than all of the listed combined... Read here and here.
Thanks, you'r right, but I always have reservations about getting enough of other nutrients that the body needs. I know there are plenty of substitutes now, but I believe in moderation and that is what the world needs to learn as well. If everyone would reduce their intake to what they needed and not to what they like ... that would already bring a huge change.
Yes, already reducing our demand for products of animal agriculture can help much more than we think. It was joy observing the photos and descriptions from your beautiful vacation!
