Replace old fossil fueled power plants? Slap massive import duty on products from countries who are major polluters to pay for the damage their total lack of regard for the rest of the planet causes? Buy more electric cars and put some effort into making them affordable? Expand Economic Exclusion Zones, set up an international naval task-force and crack down on pirate fishing fleets? Try to situate food production facilities as close to the consumer as possible to cut down on carbon emissions? Promote energy efficiency? Provide incentives for people to upgrade old buildings to reduce their energy consumption? Try to plan cities and infrastructure to create continuous habitat for wildlife and modify existing infrastructure similarly? Stop listing to ignorant and corrupt politicians who label common sense stuff like this as communism?
