Top Environmental Issues & Local Efforts


What are the top environmental concerns of 2022 and the work being done to fix them? Below are five global concerns. Each week during April, we will feature one of the issues and share the work that the County is doing to help, and introduce you to a local organization focused on the same topic. 


Climate Change From Fossil Fuels

Increased emissions of greenhouse gases have caused temperatures to rise, which are causing catastrophic events all over the world. The global climate is changing, and we directly feel and see the effects of that change locally in our communities. This includes a higher frequency and intensity of extreme heat events, droughts, wildfires, storms and sea-level rise. Furthermore, a changing climate is causing immediate and long-term damage to our ecosystem, food production, health, safety, jobs, businesses, and our overall quality of life in the San Diego region. We need a coordinated response in our region to climate change. See what’s being done to help.


Food waste

A third of the food intended for human consumption – around 1.3 billion tons – is wasted or lost. This is enough to feed 3 billion people. Food waste and loss accounts for 4.4 gigatons of greenhouse gas emissions annually; if it was a country, food waste would be the third highest emitter of  greenhouse gases, behind China and the U.S. 

Food waste and loss occurs at different stages in developing and developed countries; in developing countries, 40% of food waste occurs at the post-harvest and processing levels, while in developed countries, 40% of food waste occurs at the retail and consumer levels. (source www.Earth.org)  See what's being done to help. 



Species and habitats are becoming extinct due to human activity. This causes an imbalance in natural processes like pollination and poses a threat to ecosystems – coral reef destruction is particularly affected.

The past 50 years have seen a rapid growth of human consumption, population, global trade and urbanization, resulting in humanity using more of the Earth’s resources than it can replenish naturally. (source:www.earth.org)  See what's being done to help



Watershed/Stormwater Pollution

The San Diego region is home to 11 watersheds that all drain westward to the Pacific Ocean. As water moves through a watershed, it can pick up pollutants such as trash, chemicals, auto fluids, and bacteria, and transport them directly into streams, creeks, and rivers, and ultimately to the ocean. Preventing pollutants from contaminating our water sources is important for everyone’s health and the environment.  See what's being done to help.


Plastic Pollution

In 1950, the world produced more than 2 million tons of plastic per year. By 2015, this annual production swelled to 419 million tons and exacerbating plastic waste in the environment. 

A report by science journal, Nature, determined that currently, roughly 11 million tons of plastic make its way into the oceans every year, harming wildlife habitats and the animals that live in them. The research found that if no action is taken, the plastic crisis will grow to 29 million metric tons per year by 2040.  (Source: Earth.org)  See what's being done to help.
