I usually don't go anywhere unless I have a critical mass of invitations in one place -- anywhere from three to four to sometimes even as many as 10 or 15 talks in a given place -- so I can minimize the impact of my carbon footprint as much as possible.
Saya biasanya tidak pergi kecuali ada banyak undangan di suatu tempat -- antara tiga atau empat kadang sampai 10-15 ceramah di satu tempat -- Jadi saya bisa meminimalisir jejak karbon saya sebanyak mungkin.
