Earth as an ecosystem stands out in the all of the universe. There's no place that we know about that can support life as we know it, not even our sister planet, Mars, where we might set up housekeeping someday, but at great effort and trouble we have to recreate the things we take for granted here.
For any sport to be sustainable, it cannot survive on government or corporate grants alone. The sporting ecosystem needs more investments from businesses, and businesses need to see the returns from their investment in sport. Cricket has achieved that distinction, but I feel a country of a billion-plus people cannot remain captive to one sport.
By the time we see that climate change is really bad, your ability to fix it is extremely limited... The carbon gets up there, but the heating effect is delayed. And then the effect of that heat on the species and ecosystem is delayed. That means that even when you turn virtuous, things are actually going to get worse for quite a while.
