Call for Change
What can government and community leaders do to help with climate change and other environmental problems? Here are some plans to propose.
Create Local "No-Fish Zones"
Anyone who has done research on climate change and pollution can trace a lot of it to Co2 increase. Many people know that trees help to absorb this Co2 making them vital to the cycle of nature. However, another vital natural source of Co2 absorption is the ocean. What allows this Co2 to be absorbed is the photosynthesis in plankton and algae. These mechanisms of absorption rely heavily on the biodiversity of the ocean. This means that when humans overfish and destroy ecosystems, this cycle derails. So what can we do to help make this fishing more sustainable? A new idea called "No-Fish Zones" could be the answer. This would mean areas of gross ecosystem damage would become zones where fishing isn't allowed. As seen in trials of this solution, these areas increase in vitality so much, that the marine life started to flood into fishing zones. This supplied fishermen with more healthy fish while also helping to preserve the ocean. David Attenborough says that "estimates suggest that “no fish” zones over a third of our coastal seas would be sufficient to provide us with all the fish we will ever need."  More biodiversity means more stability which means more Co2 that can be absorbed by the ocean.

Make Renewable Energy Affordable
Over and over, we hear everyone telling us to use renewable energy and get solar panels. The truth is, it is expensive. Despite solar panel costs slowly decreasing, many households cannot spare the money to contribute to helping the environment in this way. Here are some plans that can be proposed to local government and groups to help out those who can't afford renewable energy sources and to encourage more people to get them.
Propose a tax credit for people who invest in and develop renewable energy sources. This would give incentive for people and developers to participate in sustainable energy projects.  In addition, it will overtime save some money which might make renewable energy a more attainable option for more households.
Federal Assistance funds in low income communities can be used to invest in renewable energy sources. There are many of these federal assistance programs such as the Department of Health and Human Services’ Low Income Home Energy Assistance Program.

Invest in community solar gardens. This means that a collection of solar panels feed energy into multiple houses. This energy can be used to power electricity, water, etc. and the people in the community can share the cost. 
Any of these solutions can be implemented by local and federal government. Some of these solutions could be do-able inside of specific communities or neighborhoods.
