Mangroves, salt marshes and sea grass lock away carbon at up to five times the rate of tropical forests.

Pollution from human activities is changing the Earth's climate. We see the damage that a disrupted climate can do: on our coasts, our farms, forests, mountains, and cities. Those impacts will grow more severe unless we start reducing global warming pollution now.

Wind and other clean, renewable energy will help end our reliance on fossil fuels and combat the severe threat that climate change poses to humans and wildlife alike.

When we go to the store, we bring home more than food - we bring home traces of broader environmental problems. But we can use our shopping carts and dinner plates to help solve some of those problems.

Shell has poured billions of dollars into offshore Arctic drilling, but no matter how much it spends, it cannot make the effort anything but a terrifying gamble. And if Shell, the most profitable company on Earth, can't buy its way to safety in Alaska, nobody can.

Opening up Atlantic and Arctic waters to drilling would lock the next generation into burning oil and gas in a way that only makes climate change that much worse, fueling ever rising seas, widening deserts, withering drought, blistering heat, raging storms, wildfires, floods and other hallmarks of climate chaos.

Carbon pollution contributes to climate change, which causes temperatures to rise. Hotter temperatures mean more smog in the air, and breathing smog can inflame deep lung tissue. Repeated inflammation over time can permanently scar lung tissue, even in low concentrations.

Safer chemicals and more energy-efficient technologies can provide cooling without severe climate implications. Shifting to these alternatives could avoid the equivalent of 12 times the current annual carbon pollution of the United States by 2050.

Mercury is most commonly recognized as a developmental toxin, threatening to young children and fetuses as they develop their nervous system. Prenatal exposure to even low levels of mercury can cause life-long problems with language skills, fine motor function, and the ability to pay attention.
