5 Easy Ways to Reduce Your Carbon Footprint As a Traveler - Travel and Leisure
Simple swaps can make a big difference.
Climate change. Just two simple words that somehow encompass an idea so big, most of us have no idea how to wrap our heads around it. But ignoring it could come with unfathomable consequences.
Here's what we know about climate change: It's happening very quickly. As NASA explained, the earth's climate has always fluctuated throughout history. Over the last 650,000 years, it notes, there have been "seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 11,700 years ago marking the beginning of the modern climate era — and of human civilization." Most of the climate changes to this point can be attributed to minute variations in the planet's orbit.
However, after humans came around, all bets were off.
"The current warming trend is of particular significance because it is unequivocally the result of human activity since the mid-20th century and proceeding at a rate that is unprecedented over millennia," NASA wrote. "It is undeniable that human activities have warmed the atmosphere, ocean, and land and that widespread and rapid changes in the atmosphere, ocean, cryosphere, and biosphere have occurred."
