Is the solution to biodiversity loss to collect, preserve and catalgus seeds o Svalbard contains the seeds of over 400 000 plant species in a ‘Noah’s Arc’ of agrobiodiversity Ecomodernism - Continue to pursue intensification through breeding and genetic manipulation o while maintaining some ‘wild nature’ through conservation reserves o preserving biodiversity in storage - Is the best plan to put seeds in the freezer at Svalbard o Majorly expensive o As much as 75% of global crop diversity exists outside the main seed banks o And are used by some of the world’s smallholder farms 3 rd Global Biodiversity Outlook - Ecomodernist in outlook o Much greater efficiency in the use of land, energy, fresh water and materials to meet growing demand o Use of market incentives and avoidance of perverse subsidies to minimize unsustainable resource use and wasteful consumption o Strategic planning in the use of land, inland water and marine resource to reconcile development with conservation of biodiversity Resilience and Diversity - Redundancy o Where elements duplicate the same function in a system - They provide ‘backup’ or ‘insurance’ in case of the loss or failure of some system elements

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
