What is the alternative to flying, if you want to heal the environment? See detail.

Walking.

The alternative to flying for me would be not seeing my grandchildren.

But for this movement, I think they are encouraging people to vacation near home.

Heal the environment by stopping all the dirty coal fired and dirty oil fired manufacturing facilities in China and okayed by Trump in the USA.

That is a bigger impact to clean air.

Heal the environment? Start by setting a good example: DON’T HAVE CHILDREN!

Virtual Reality. Upload your mind to the internet.

@ragingloli You mean we haven’t already?

Take a staycation instead of a world trip.

Some options, as may fit your situation:

Take a train.

Take fewer more extended trips rather than many short ones.

Explore places that are closer to you.

Did they make the solar plane more feasible yet?

The alternative to flying is wooden ships. Are we ready for that?

They want you to trade in your carbon footprint for a new footprint.

How about people who fly for work?

They can walk.

Take a boat with no engine over seas? like a canoe. Canoe all the way to Japan

The Vikings did it!

@SergeantQueen
There is this whacky sci-fi concept out there. You may have heard of it.
They call it a “sail”.

Yes but Canoes are more fun.

A catamaran is a canoe with a sail.

They were used a lot for whale hunting.
