Motion detectors make sense in all rooms including outdoor areas, where we potentially let the light burn for too long, for example in the hallway, basement, garage, etc. Of course, it is important that the light does not stay on for too long.

Modern lamps require little electricity, and yet it is worthwhile not to let them burn unnecessarily, for example when we are not in the room for a long time. Corridors, toilet rooms, cellars often have the light burning unnecessarily. In some indoor and outdoor areas, companies also sometimes have the light on too long or too early.

We can use rainwater at least for garden irrigation in the case of unproblematic materials of the roof. With significantly more effort also for washing machine and toilet flushing. Even if it takes quite a long time economically before it's worth it, it's a good thing.

Air conditioning systems are also gaining in importance in temperate latitudes. Intelligent construction and ventilation and the use of thermal protection roller blinds can avoid these power guzzlers. In warm regions, a corresponding education of the guests can take place. Often a fan is also useful.

Vegan means refraining from fish, meat, milk, cheese and other animal foods. Unthinkable for many people, on the one hand because of the taste, and on the other hand because they consider it unhealthy. To the taste, it can be said: Among the extremely diverse vegan alternatives, something certainly tastes just as good or even better. We just have to try it - from vegan cheese to egg salad to burgers. Many celebrities and athletes are vegan. Vegan is booming. Regarding health, it must be said: Our early ancestors ate healthier than we eat today. There was mixed food with only little meat and fish and also little grain and instead more legumes. If you eat a vegan diet, you have to pay attention to two nutrients: vitamin B12 and unsaturated omega 3 fatty acids. B12 can be bought for sucking (or as an additive in foods that are no longer called organic). Omega 3 fatty acids are available in linseed and algae oil. After a few months vegan, a blood test can show whether there are deficiency symptoms. As a rule, vegans eat healthier and are fitter than others. What else does it bring: In addition to ethical reasons (keeping and killing animals), vegans help to prevent the deforestation of forests, because most areas in the world need the feed. In fact, we will not be able to feed the growing world population in the way we Germans. Vegans also prevent greenhouse gases from the methane emissions of cows, save enormous amounts of drinking water and prevent the pollution of soils, groundwater and waters.

Unlike the vegan diet, a vegetarian diet can also include milk, cheese or eggs. Vegetarian days are healthy, mean less animal husbandry and thus less consumption of land and water. People in the industrialized world consume more than three times more animal products, which according to the EAT-Lancet Commission would be healthy for us and the planet. We don't have to become vegans or vegetarians right away, but maybe just flexitarians.

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.

Organic is extremely important for biodiversity. We have the greatest species extinction since the extinction of the dinosaurs and the consequences are greater than those of climate change. Pesticides and mineral fertilizers endanger our future. In addition, soils from organic farming usually store more carbon and thus help against the climate catastrophe. The counter-argument is often that the yields in organic farming are lower than in industrial agriculture and therefore more forests have to be cut down. This is true, for example, with cereals that are not unrestrictedly healthy. But if we eat less meat, waste less food and eat more healthy legumes, we have plenty of additional space available and can feed the entire world organically and even plant a little more forest. Organic in the canteen or at the kiosk or at company events is of course more expensive - but if it is not exemplified somewhere, what do we expect in the private sector.

Which is better - the organic apple from New Zealand or the sprayed apple from the region? Answer: both wrong. Organic food from the region means less transport and is therefore even better than organic food with wide transport. Organic in the canteen or at the kiosk or at events is of course more expensive - but if it is not exemplified somewhere, what do we expect in the private sector. Sometimes a direct delivery from providers from the region is a way to save costs.

Seasonal organic products in addition to regional organic products also have less energy expenditure for storage. In the respective months, other products are available seasonally, so that we can eat healthy and tasty all year round with little transport and storage effort with regard to a seasonal calendar.

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. Canteens and kiosks and also events can query the demand in advance and thus prevent food from being thrown away. A dish can also be deliberately offered the next day, which advertises the utilization of the leftovers from the previous day.

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.

Many things are actually thrown away, although others could still do something with it. It is more convenient for us not to repair it than to have a stand at the flea market or to have to send it for little money. But the good feeling of doing the right thing motivates. A company can avoid garbage here - even if throwing it away probably meant little effort.

Insect hotels or just old, higher tree stumps and dead wood on the ground, nesting boxes and, if useful, bat boxes are great ways to maximize biodiversity in your own environment. School classes can also participate here.

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.

Do we harm the regional organic farmers when crops, such as orchards, grow on public land? No, because hardly anyone will be able to take care of it themselves. Rather, the main problem is the use of land. English lawns, ornamental plants, weed destruction, etc. harm the soil and biodiversity. Instead, nature-friendly crops are needed. If a company shies away from the maintenance effort, permaculture and the cultivation of perennial plants may make sense. Also, the cooperation with beekeepers and school classes, the possibility of public gardening and sponsorships are great measures for a better world. Urban gardening is also popular when companies have raised beds on their roofs and offer employees something to relax and have a bite.

Road salt is convenient and safe, but a considerable burden for pets, the trees and the surface water. Replacing this with split means more effort, but it's worth it.

This is about living and working in the region, about strengthening the community. The birdhouse from a social workshop or the PV system from the electrician on site (if he has further training). The award criteria of the municipalities must of course be legally secure. If the work is good, a discreet advertising sign can also draw attention to the craft business in return.

At Fair-Trade, we usually think of the label of the same name - which is no longer in disrepute. But there are also other labels - some rather greenwashing, some quite trying to do better. Fair is not always the same as organic and organic is not always fair (but some labels combine both). The importance is immense: fair working conditions in the world ensure less migration, more climate protection and a more peaceful world. Extremely remarkable is the background of chocolate and the connection between child slavery (!) And the common products from Nutella to children's chocolate to the Mars bar: https://edition.cnn.com/world/freedom-project Companies and events can therefore be pioneers for a better world themselves here in the food or in the work clothes or the hand-sewn football.

This is about workwear or, for example, in the tourism sector clothing with advertising. Vegan shoes and belts are no longer distinguishable from their leather variants. And who pays attention to the fact that the tanning processes do not allow heavy metals to enter the environment or that the leather is certified accordingly? We should be careful with some plastics, such as PVC with plasticizers, which are also not good for the environment.

Leaf vacuums and blowsers are even worse than the idea of mowing small lawns with a large lawn mowing tractor at all and then for hours. Boys with toys. The leaf vacuums and blowers emit noise and ultrafine particles and harm the soil organisms more than rakes or brooms.

Unfortunately, many devices can no longer be repaired at all, for example if the control unit breaks down from the washing machine and costs more than a new washing machine. And yet there are workshops that also repair mobile phones, washing machines, lawn mowers, etc. - and even if it is as expensive as a new device, it is the good feeling of having done something for a better world again.
