What to do against planet's warming up and energies depletion ?

That's a good question. It's a pity that, just as travel has become cheap and affordable, which allows us to travel around the world, it turns out that the fuel from all that travel is damaging the very world that we were hoping to visit. If only we could invent a solar-powered aeroplane.

personally i like it when its getting warm in the summer but i don't like the planet to warm up. We don't know what the effect is on the longer term and we can't have a trial.
