Chainsaws, bulldozers and oil rigs threaten to despoil these havens of biodiversity, regulators of climate and sanctuaries for recreation. NRDC's BioGems Initiative works with online activists and local partners to defend our hemisphere's most imperiled ecosystems.America's dependence on fossil fuels is a major contributor to global warming, toxic air pollution and dependence on some of the world's most oppressive regimes. By investing in renewable energy sources such as the sun, wind and biomass, we can help solve the energy and climate crises. Investing in energy efficiency can also stimulate the economy by creating millions of new green jobs, putting us squarely on the path toward repowering America with clean energy.Ninety percent of large fish such as tuna and swordfish are already gone.
