We need to encourage large multinational companies, not just governments, to do more to prevent biodiversity loss. The only way to do this is to stop buying their products. If enough people do this they will have to switch to more sustainable raw materials and production. The problem is how do we know? Maybe this is something the government can help with.
The demand for resources by human society is a key factor in biodiversity loss, and 'encouraging' companies to assess the impact of their activities is a crucial factor. What is the cost to species on the methods of production of suppliers - do companies audit their supply chains to see? Do companies audit their own production methods - cradle to grave - for biodiversity impacts, alongside energy use and materials recycling? Consumers should be demanding more, industries should be developing better and transparent accreditation systems alongside fairtrade marks and other ethical investment devices. Customers, shareholders and others should be able to see environmental statements as a part of legally required company accounts - including biodiversity impact, alongside other aspects of the company's performance.
The good news is that this is being seen by some enlightened companies who are taking a more environmentally aware line, so use your green pound to support those trying to make a difference. Also ask questions and 'lobby organisations' about how they take biodiversity preservation into account. Two American monsters - MacDonalds and Walmart have dramatically changed their practice because of consumer pressure, moving their supply away from 'rain-forest beef' and only purchasing sustainable timber supplies. Enlightened consumers are an important part of the answer - rewarding companies who make a difference, and pressuring those which don't through our purchasing is a powerful tool. Governments also need to be involved in how they subsidise and tax business, so that Government supports a green, biodiversity-aware industry and penalises business which does not attend to their environmental impact.
