Buy and eat from local, sustainable farms. Consider broader impact when "upgrading". Donate used electronics to organizations that refurbish and reuse them. Donate to organizations that plant trees with minimal overhead.

Step outside the surface level boxes that have people protesting over straws and consider your larger usage. Stop buying products from countries that have horrible track records for environmental waste and pollution. Inform those politicians that represent you that you want a higher level of accountability.

To the aoc/green-new-deal supporters, drop the socialist and identity politics and push legislation centered on specific issues that can be implemented independently.
