Climate change is one of the most devastating problems that humanity has ever faced—and the clock is running out.
For over 200 years, humanity has powered itself with fossil fuels like oil and coal. We’ve seen an enormous amount of development and progress—but at an incredible cost.

Raising livestock accounts for roughly 15 percent of global greenhouse gases. 牛尤其有害, 因为它们的消化系统会释放甲烷, 一种强大的吸热气体.
以避免617888九五至尊娱乐变化的最坏影响, we need strong leadership and nationwide policy changes. Write and call your elected officials, participate in local meetings, and, above all, vote.
