1) Crop diversity is the basis for our food security. From today's perspective, we can only estimate which “genetic resources” will be "valuable" or vital in the future. Therefore, it is careless to discard or destroy the diversity of old and rare local crops.

2) Diversity strengthens nature’s defensive forces. It helps in the mitigation of disturbances in agro-ecosystems. The more diversity, the more stability. This yield security also serves people.

3) Diversity means pleasure and quality of life! Anyone who has ever bitten into a juicy and aromatic rare variety of tomato from a farmer’s market, has savoured the flavour of an obscure variety of apple, or enjoyed the unique taste of home-grown vegetables knows the difference, and therefore knows what is at stake.

4) Crop-diversity is part of our culture. The history of crops is a common story of mankind and plants. The plants which feed us also form us. Typical dishes, customs, festivals, traditions and local knowledge will be lost forever if the plants disappear.

5) Diversity helps save money. According to calculations by the United Nations, by 2050 the loss of species will cost Europeans more than $1.1 trillion Euros per year. The loss of species will reduce the global Gross Domestic Product (GDP) by three percent annually.

6) Diversity supports adaptation to extreme weather conditions. Under today’s pervasive and perennial threat of climate change, locally adapted plants are an important resource of different biological characteristics which could help to sustain crop yields in the future.

7) Diversity contributes to food sovereignty. Today, ten agrochemical corporations dominate the global seed market, creating a substantial dependence among farmers. Countries that promote regional crop varieties and allow seed exchange with their policies will in turn foster greater independence from these corporations.

8) Diversity reduces the necessity of pesticides. Monocultures and toxic pesticides go hand in hand. In a sustainable, diverse agriculture with robust plant varieties, pesticides become dispensable.

9) Diversity helps people with allergies. Among the thousands of (still) existing crop varieties, alternatives can be found for people who suffer from allergies. By the way: today, 90 percent of the global food harvest comes from approximately 100 different species, even though it is possible to utilise more than 4,800.

10) Preserving diversity is also a moral obligation. The diversity of life is a value in itself and is thus worthy of protection. We cannot assess the impact of our interventions on nature’s complex relationship structure. Therefore, it is our duty to take precautionary measures.
