The area that we need to live means the area that is sealed, the building material that is needed, and the space that needs to be heated - and all this against the background of social justice. If you offer an apartment, a holiday house, or a hotel room and additional rooms smaller versions can be a smart choice.

Food from the region, from the weekly market and from the farm shop have not been transported far (there are of course also exceptions there) and strengthen the local economy. However, there are also inefficient short transport routes when vehicles with little load drive to the points of sale. E-mobility and cargo bikes can help here. Unfortunately, the regional is often also played out against the organic offer: regional, sprayed with pesticides food is not as good as regional organic food, and regional meat is not as good for the environment as the renunciation of meat.

Fortunately, tap water has long been a trend. There are drinking water dispensers in schools and the students have their drinking bottles with them, and managers also bring their drinking bottles to workshops. Many children do not even get used to the unhealthy sugar drinks. Tap water is more strictly controlled than bottled drinks and saves a lot of energy and packaging. Even with motorhomes or boats or in places with the smell of chlorine in the water, we can save a lot of money, energy and packaging through good and regularly exchanged filters.

Food is wasted from the field to the factories and transport routes to the throw away by us, the restaurants and the supermarkets. This ultimately means that more areas are needed for cultivation and thus forests are cut down and biodiversity is endangered with sprays and fertilizers. We can shop more specifically, throw away goods not only because of the best before date, save food in the household (e.g. freeze bananas or make durable spreads and soups from leftover vegetables yourself), save specifically rescued food (e.g. too small or wrinkled goods) and also donate leftover food in many places, e.g. to the food banks.

We are used to the fact that everything is packed and we don't care much about the packaging. For some foods, the packaging is more expensive in the production than the content. Paying attention to the packaging sends a signal to manufacturers and retailers. Refills are an option as well. For food, there are so-called unpackaged shops or at least the possibility of using deposit containers (own step) or cotton bags brought along for loose vegetables and fruit. In basically all markets, we should have our own bags with us.

Consistently separating waste, including green waste, glass and paper, is not as self-evident as can be assumed. Many make little effort here and don't really know what belongs in which bin. The residual waste bin also costs the public sector a lot of money, while the recyclable and green waste bin are free of charge. But also special waste, such as batteries, incandescent lamps, electrical appliances, etc. must be disposed of properly. Hospitality businesses and events can place separating waste bins with information signs everywhere. In general, it is also possible that a sign indicates that the cleaners take over the separation for the guests. But better, the guests can do that.

Non-recycled paper is often cheaper, but means cutting of forests, contamination of water during production and a high energy requirement. Recycled paper for toilet paper, writing paper, packaging, envelopes, wrapping paper, etc. should be a matter of course today. But we have to pay attention to it and choose it. Recycled paper is also snow-white, but it should then not be bleached with chlorine but oxygen. A note on the menu can make you proud and contribute to corporate identity.

Garbage collection as an event also for the clubs with subsequent meeting, possibly sponsored by the local economy, helps to get nature clean and to raise awareness. Tourism companies can be organizers, sponsor or participate as a team. Plogging is also very popular - the combination of jogging and garbage collection.

Surface sealing is a problem not only in growing civilizations, but also in Germany. We live on too much living space, are still building new streets and courtyard driveways and our terraces are also getting bigger and bigger. To specifically dispense with area, to build in height, water-permeable paving, green roofs (own point) and, weighing up all the advantages and disadvantages, to expand one's own house to the height in order to enable more people to live on the same sealed area, are valuable steps. By the way, an English lawn is ecologically not very valuable, for example, compared to a flower or clover meadow or a vegetable garden. Guest companies can systematically look at which areas do not have to be sealed and may be provided with flower meadows. An info sign can then make you proud.

In the past, it was considered controversial whether birds should be fed, or whether they forget to find food themselves and instead promote the concentration of many birds in one place diseases. Today it is clear that with our well-kept gardens, leaf vacuum cleaners and perfect combine harvesters, we leave too little for the birds and they have to be fed. Many argue that we should even feed them in the summer.

It is hard to believe that the future of our diet depends on the use of pesticides and their influence on insects that have to pollinate our plants. Many pollinators are threatened with extinction and in addition to the purchase of organic, we can offer these insects flowers on our areas. In fact, some plants are neither bee-nor bird-friendly. On the other hand, fruit trees and most vegetables are already great opportunities to promote bees, bumblebees, etc. At the flower meadows there are one- and multi-year-olds.
