Chronic exposure to soot is associated with shorter life expectancies, lung cancer, diabetes and low birth weight and can exacerbate respiratory and cardiovascular illnesses.

Refineries and chemical plants are major emitters of not only nitrogen oxide, but sulfur dioxide, which also contributes to smog and haze.

Now California is crafting a similar policy for trucks. State regulators are expected to vote on rules in June that would require truck manufacturers to sell all-electric or fuel-cell trucks in the state

Some truck manufacturers have pushed back against the proposal, saying the market for selling electric trucks hasn't developed yet.

California also has an ambitious target for putting 5 million electric cars on the road by 2030. That could help lower emissions because instead of burning gasoline, those cars would run on electricity, largely generated by solar, wind and hydropower in the state.

Pollution from burning coal also affects a larger area than vehicle emissions, which means modest air pollution reductions in East Coast states may partly be because of their location downwind of coal-fired facilities.

Emissions from those sources, combined with hot and stagnant weather, cause air pollution to hit dangerous levels during the summer, which puts the region out of compliance with federal air standards

Climate change is making people sick and leading to premature death, according to a pair of influential reports on the connections between global warming and health.

Longer, more intense heat waves are a particularly deadly effect of global warming around the world, and older people are most at risk.

A New Mexico state law requires killing any wild animal who has attacked a human, then testing that animal for rabies; the bear was killed the day after Williams was injured.

Many states on the East Coast allow wildlife officers to consider the circumstances that led to an attack when deciding whether a bear should live or die."

If we use common sense and take precautions we may save animals' lives, as well as our own

Even if there was a change in administration that wanted more environmental regulations, every day that we don't reduce carbon emissions is a problem,” she says. “Every additional unit of carbon that's emitted into the atmosphere is a problem.”

The review process makes agencies consider alternatives that reduce the negative impacts of the original plan, such as building a highway around a protected habitat instead of through it, she says. Now, even fewer projects will go through this process.

The Trump administration has been busy during the pandemic, reshaping and rolling back long-standing environmental regulations on water, air and climate change.
