und Tiere finden weniger Nahrung, bis sie sich schlie\u00dflich ganz zur\u00fcckziehen. (Dazu beu Urban Gardening mehr). \u00a0<\/span><\/p>\nZu dem werden Tiere und Pflanzen an immer mehr Orten durch Abgase, L\u00e4rm und Licht in ihrem Lebensraum gest\u00f6rt. W\u00e4hrend der L\u00e4rm die Nachtruhe mancher Tier st\u00f6rt, kann das Licht die Wahrnehmung von Insekten und Flederm\u00e4usen der-ma\u00dfen st\u00f6ren, dass sie auch daran sterben. Jeden Abend kann man Insekten bei ihrem letzten \u201cTodestanz\u201d um Laternen und andere Beleuchtung sehen, an dessen Ende sie ersch\u00f6pft zu Boden gehen und versterben. Mit der Earth Hour Ende M\u00e4rz soll auf die Lichtverschmutzung vor allem in der Nacht aufmerksam gemacht werden.<\/p>\n
Wichtig ist aber:<\/strong> nat\u00fcrlich hat sich das Klima schon immer ver\u00e4ndert und ist f\u00fcr Pflanzen und Tiere in dem Sinne nichts neues. Allerdings vollzog sich ein Klimawandel vermutlich noch nie so schnell, wodurch den Pflanzen und Tieren viel weniger Zeit bleibt sich den neuen Bedingungen anzupassen. Problem ist hier vor allem, dass auch noch viele andere Stressfaktoren in sehr kurzer Zeit aufeinander treffen, so dass den Pflanzen und Tieren kaum Zeit zur Anpassung bleibt, und sie drohen, auszusterben.<\/p>\nWhat is biodiversity and why is it important?<\/h1>\n

What is biodiversity and species protection?<\/h3>\n
According to the UN Convention on Biological Diversity, biodiversity is ‘biological diversity’ or ‘the variability among living organisms from all sources, including, inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species and of ecosystems’. Biodiversity is under threat due to various factors, which we explain in the same way. However, since it is important for the Earth’s habitat, a number of laws, guidelines and agreements have been passed at national, European and international level to protect biodiversity (e.g. the Federal Nature Conservation Act, the EU Species Protection Regulation or the Washington Convention on International Trade in Endangered Species of Wild Fauna and Flora). (cf. Federal Agency for Nature Conservation – BfN) This involves, for example, the conservation of natural habitats and wild bird species, plants and other animals as well as the protection of migratory species. (cf. BfN).<\/p>\n
Why is species protection important?<\/h3>\n
There can be several good reasons for wanting to protect species and preserve biodiversity. We have collected some of them for you here:<\/p>\n
\n- The Grundgesetz states that the natural foundations of life must also be preserved for future generations. We therefore have a responsibility towards future generations to preserve biodiversity. (cf. BfN)<\/li>\n
- Many animals and plants are part of an ecosystem from which people also draw their food and a whole range of raw materials. Without these ecosystems and their individual components, i.e. the various animals and plants, food and raw materials would also become scarce. (cf. BfN)<\/li>\n
- Many plants contribute to cleaner air and water.<\/li>\n
- The more species-rich an ecosystem is, the more flexible and healthy it is and the better it can react to change and stress. In particular, diseases spread much faster and more severely in monocultures, while biodiversity creates a certain robustness.<\/li>\n
- The different species interact with each other and are in a relatively stable balance with each other. Massive interventions endanger this balance and lead to permanent changes whose effects are uncertain.<\/li>\n<\/ul>\n
Was gef\u00e4hrdet die Biodiversit\u00e4t?<\/h3>\nClimate change<\/h4>\n
Depending on the scenario, 20-30% of animal and plant species are increasingly threatened with extinction due to climate change. But what exactly does warmer weather have to do with the loss of animal and plant species?<\/p>\n
Increasingly warmer weather changes ecosystems: some plants and animals move northwards and disappear from their original habitats, while other plants bloom earlier. Both of these factors lead to their disappearance as food or beneficial organisms for other animals and plants. As a result, some pests, such as the bark beetle, can spread more easily. Also, new, thermophilic plants settle in, which in turn can bring new pests and\/or diseases that are completely unknown to the native plants. If these new exotic plants then also spread widely, they can again be a danger for native plants, which in turn become scarcer as a source of food or use for other animals and plants. In short, warmer weather changes individual components of the ecosystem, but these changes have a major impact on the entire ecosystem.<\/p>\n
Pesticides, fertilizers and industrial agriculture<\/h4>\n
Pesticides are toxic to many insects and these toxins also enter our groundwater. In addition, nitrate pollution of water and soil is caused by over-fertilisation. What effects the poisons and nitrates have on human health is still uncertain today.<\/p>\n
The increased use of pesticides results mainly from industrial agriculture. Today, plants are increasingly grown in large monocultures – i.e. only one plant exists on large fields – so no ecosystem can be created. Pests gain the upper hand because they can spread more easily, and farmers are using more pesticides.\u00a0A similar game results for diseases, since monocultures often have a greatly reduced gene pool. This in turn leads to a reduced resistance of the plant population to disease.<\/p>\n
At the same time, industrialised agricultural land also offers less and less habitat and food for animals. If all plants in a large area bear flowers or fruit at the same time, there will be a significantly reduced food supply in the remaining months. And where should animals actually furnish their living rooms if the areas are regularly worked with heavy equipment?<\/p>\n
Surface sealing and noise, air and light pollution<\/h4>\n
Increasing urbanisation also means that there is less and less natural habitat for animals and plants. In many cities, for example, there are only a few plants, land is increasingly sealed and animals find less food until they finally withdraw completely. (We already talked about sealing and greening in cities two weeks ago during the Urban Gardening session).<\/p>\n
In addition, animals and plants in more and more places are disturbed by exhaust fumes, noise and light in their habitat. While noise disturbs the night’s rest of some animals, light can disturb the perception of insects and bats to such an extent that they die from it. Every evening insects can be seen dancing their last “dance of death” around lanterns and other lighting, at the end of which they go down to the ground exhausted and die. The Earth Hour at the end of March is intended to draw attention to light pollution, especially at night.<\/p>\n
However, it is important to note<\/strong> that the climate has of course always changed and is nothing new for plants and animals in this sense. However, climate change has probably never happened so quickly, leaving plants and animals much less time to adapt to the new conditions. The main problem here is that many other stress factors also come together in a very short time, leaving plants and animals hardly any time to adapt, and they are threatened with extinction.<\/p>\nTranslated with www.DeepL.com\/Translator (free version)<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"Weil Biodiversit\u00e4t wichtig ist f\u00fcr eine gesunde Umwelt, erkl\u00e4ren wir euch heute was Artenschutz ist, und warum Arten immer mehr bedroht werden. \/\/\/ As biodiversity is important for an healthy environment, we’ll explain to you what protection of species is and why species become more and more threatened.<\/p>\n","protected":false},"author":4,"featured_media":9788,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"neve_meta_sidebar":"","neve_meta_container":"","neve_meta_enable_content_width":"","neve_meta_content_width":0,"neve_meta_title_alignment":"","neve_meta_author_avatar":"","neve_post_elements_order":"","neve_meta_disable_header":"","neve_meta_disable_footer":"","neve_meta_disable_title":"","footnotes":""},"categories":[12,31],"tags":[],"class_list":["post-9787","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-nachhaltigkeit","category-themenwochen"],"translation":{"provider":"WPGlobus","version":"3.0.2","language":"gb","enabled_languages":["de","gb"],"languages":{"de":{"title":true,"content":true,"excerpt":true},"gb":{"title":false,"content":false,"excerpt":false}}},"_links":{"self":[{"href":"https:\/\/www.asta-trier.de\/gb\/wp-json\/wp\/v2\/posts\/9787","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.asta-trier.de\/gb\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.asta-trier.de\/gb\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.asta-trier.de\/gb\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/www.asta-trier.de\/gb\/wp-json\/wp\/v2\/comments?post=9787"}],"version-history":[{"count":1,"href":"https:\/\/www.asta-trier.de\/gb\/wp-json\/wp\/v2\/posts\/9787\/revisions"}],"predecessor-version":[{"id":11089,"href":"https:\/\/www.asta-trier.de\/gb\/wp-json\/wp\/v2\/posts\/9787\/revisions\/11089"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.asta-trier.de\/gb\/wp-json\/"}],"wp:attachment":[{"href":"https:\/\/www.asta-trier.de\/gb\/wp-json\/wp\/v2\/media?parent=9787"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.asta-trier.de\/gb\/wp-json\/wp\/v2\/categories?post=9787"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.asta-trier.de\/gb\/wp-json\/wp\/v2\/tags?post=9787"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
