Today, I’m thrilled to announce I am launching the Bezos Earth Fund.⁣⁣⁣ ⁣⁣⁣ Climate change is the biggest threat to our planet. I want to work alongside others both to amplify known ways and to explore new ways of fighting the devastating impact of climate change on this planet we all share. This global initiative will fund scientists, activists, NGOs — any effort that offers a real possibility to help preserve and protect the natural world. We can save Earth. It’s going to take collective action from big companies, small companies, nation states, global organizations, and individuals. ⁣⁣⁣ ⁣⁣⁣ I’m committing $10 billion to start and will begin issuing grants this summer. Earth is the one thing we all have in common — let’s protect it, together.⁣⁣⁣ ⁣⁣⁣ – Jeff

This comes after Amazon has come under scrutiny for their carbon footprint made by the convenience of the company’s 2-day and overnight shipping. Bezos himself also faced criticism for giving $690,000 to Australian wildlife relief following the devastating brushfires, which many felt was low for Bezos, who is worth an estimated $130 billion. ⁣⁣
