Carbon dioxide is making its way into Earth, or should I say, it's already in Earth. Carbon dioxide is released by the seconds. Even now.. as we respire.. The most ideal way is for us to stop breathing - that would certaintly be the best way to save the Earth. However, we would end up dying out of breathlessness.
Cars.. Is it really a neccessity for all? Think about the kms you travelled and link back to how much carbon dioxide was emitted. Feeling guilty? As much as possible, try to walk, or at least cycle. It does not hurt to exercise. Exercise is good for your health. We should all try to hitch a hike more often. What you can do to attract drivers is to put a big signboard infront of you stating where you are going. I am sure most of you have heard about the hydro-powered car. Even though it has a low horse power, you can save a lot of money and also contribute in saving the Earth. If not, public transports are always there for you.
Buses and trains are up to 5 times more energy efficient than the car. Using public transport also saves space on our streets. A double-decker bus carries the same number of people as 20 fully occupied cars but takes a seventh of the space. That helps to prevent traffic jams which are especially harmful on our environment. If the average speed decreases from 50 km/h to a walking level of 3.5 km/h , the car needs six times more petrol than normal. Cycling and walking are of course even cleaner and healthier!
